强调投资应追求收益与权重的双重最大化。
@RJCcapital 正确的座右铭是： 最大化收益，最大化收益。 （市场，权重） https://t.co/e5oKDsYcz7

承认短期回撤，强调选股能力与避免高位追涨的重要性。
@soulbiri1 是的，我也亏损不少。即使是最好的投资者，短期内也会出现这样的回撤（Drawdown），但如果他们懂得如何挑选个股，且不在此类价位做多 $RGTI $OKLO 这类股票，长期来看应该能跑赢市场。
英文原文
@soulbiri1 Yep I’m down a lot too, even the best investors have drawdowns like these short term but should outperform longer term if they know how to pick individual stocks + not long $RGTI $OKLO type stocks at these levels.

期权到期引发波动，短期看算法，中长期看基本面。
明天有很多期权到期（如果你看 $NBIS 到 $META 等）。未平仓合约链(open interest chains)将被清洗。我想说从周一开始到1-2月，或者12月初会有复苏，但由于这是由算法驱动的，基本面没有太多实质性内容，不确定伟大的算法之神(algo gods)短期内会怎么做。中长期基本面更重要。
英文原文
lot of option expiration tomorrow (if you look at $NBIS to $META, etc). and open interest chains will get flushed. I want to say starting Monday into Jan-Feb, or maybe recovery in early December but since it's algorithmic driven with nothing too material to fundamentals, not sure what the great algo gods will do short term. Medium-long term fundamentals matter more.

鲍威尔讲话料重申NBIS优于IREN，建议关注个股基本面而非宏观大盘。
杰罗姆（鲍威尔）大概会上台，宣称 $NBIS > $IREN，然后在他走向由悉尼·斯威尼（Sydney Sweeney）坐在副驾的新兰博基尼时潇洒离场（mic drop）。 市场会鼓掌欢呼，因为他说的不过是众所周知的事实。 但除此之外，我们可能会获得更多关于12月降息以及政府停摆后经济前景的见解。大盘随后的走势可谓五五开，因此除非你交易短期指数或更依赖宏观的资产，否则关注个股基本面更为重要。
英文原文
Jerome will probably go on stage, say $NBIS > $IREN, and micdrop after walking offstage to his new lambo that Sydney Sweeney is riding shotgun in. Markets will clap and cheer knowing he said something everyone knows as a fact. But that aside, we’ll probably get more insights into Dec rate cut and a view of the economy after gov blackout. It’s a coin flip direction the general markets go after, so more important to look at individual stock fundamentals unless you trade short term indexes or more macro dependent assets

解析高波动股因机械对冲导致的剧烈震荡及反转机制。
Nebius [$NBIS] 在一个月内经历了从 $140 -> $94 -> $130 -> $83 的剧烈波动。对于波动性股票，如果一周内能下跌 25%，那么一周内反弹 33% 也是可能的。机械对冲（Mechanical hedging）会导致股价剧烈下跌，但当风向转变时，反向情况同样会发生。
英文原文
Nebius [ $NBIS ] went from $140 -> $94 -> $130 -> $83 in the span of 1 month. With volatile stocks, if something can drop 25% in a week, it can also back up 33% in a week. Mechanical hedging brings a stock down violently, but when the switch flips, the same happens in reverse. https://t.co/YmzL7OqeWw

建议无视短期噪音持有AI股，等待剧烈反弹。
🎯. 我们以前见过类似的情况，比如 $NBIS 从 $140 跌至 $94，然后在两周内暴力反弹至 $130。这次似乎更广泛且回撤时间更长，大多数高贝塔股票从 $SMCI 到 $RDDT 都在下跌，其中 AI 板块集中度最高。正如你所说，任何反弹可能都会很剧烈，因此最好在这些波动时期持有，以免错过 1-2 个最大的反弹日。显然，当前的市场下跌是多方面的，包括散户投降、保证金清算、宏观因素，以及对 GPU 过时/AI 交易信贷收紧的一些合理担忧。然而，最重要的是关注基本面而非短期噪音（目前恐惧与贪婪指数处于 9/100 的极度恐惧状态）。
英文原文
🎯. We've seen this before with stocks like $NBIS on the drop from $140 -> $94 and then the violent recovery to $130 all in the span of 2 weeks. This time it seems broader + longer drawdown with most high-beta stocks dropping from $SMCI to $RDDT with highest concentration of AI sector. As you mentioned, any recovery will likely be violent, which is why it's better to hold through these volatile times, than missing out 1-2 of the biggest recovery days. Obviously the current market drop multi-facted with retail capitulation, margin liquidation, macro, and some valid concerns over GPU deprecation/credit tightening of the AI trade added on top. However, the most important thing is to look at fundamentals over short term noise (with fear and greed being extreme fear right now at 9/100).

高贝塔资产遭抛售属市场重置，基本面改善应耐心持有。
从 $RKLB、$HOOD、$BTC（现89k）、$HIMS 等所有高贝塔/“风险”/成长型资产都在被无情抛售。尽管基本面全面改善，但这源于连环保证金清算和投降式抛售（基于部分合理的担忧）后的良好重置。以 $IREN 为例，散户仅因 Robinhood 数据就在股价创新低时抛售。但散户通常是在 $MSFT 交易后 $80 高点买入，而在崩盘后 $45 低位最后卖出。此时只需关注新周期、降息、期权到期，并耐心等待，因为基本面正在全面改善。如果盈利和远期收入放缓，我会大幅减仓（但事实并非如此，我们看到的是创纪录的增长）。
英文原文
Every high beta/“risk”/growth asset from $RKLB, $HOOD, $BTC (89k now), $HIMS is being obliterated. It’s a great reset from cascading margin liquidations and capitulation (based on semi-valid concerns) despite seeing improving fundamentals across the board. $IREN retail is selling off for example just based on Robinhood data even while stock is at new lows. But retail is typically the one to buy at the highest point $80 post $MSFT deal and and last to sell eg. $45 post crash. At this point it’s just new cycles, rate cut, option expirations, and waiting since fundamentals are improving across the board. If earnings were slowing and forward revenue was slowing, I would be selling well (but it’s not, we’re seeing record growth)

澄清研究框架，强调信贷与债务风险对板块的影响。
两件事： - 阅读时最好越过第一句继续往下看 - 隔一个交易日再看帖子，百分比数据会发生变化。 我尊重你的专注，但你正在聚焦于一个无人进行的直接对比。这确实是一篇长文，大多数人可能会跳过正文直接看评论，但文中所做的唯一直接对比是： - NeoClouds（新云厂商）与Mag7（科技七巨头）的合同 - NeoClouds与资产负债表健康的公司 - 未与OpenAI直接签约的NeoClouds 所以再次帮你梳理一下，整篇文章的核心是关于信贷市场、债务结构、OpenAI资本支出悬顶，以及影响整个板块的生态系统风险。 使用1周到1个月的时间框架是为了展示NeoClouds从何处下跌（例如$IREN在微软交易后），以反映板块在盘前的整体下跌。使用隔一个交易日NeoClouds从盘前跌幅中恢复后的不同价格，并不会改变或有利于该论点。 阅读时最好越过第一句（我也持有$IREN）
英文原文
So two things: - It helps to read past the first sentence - percentages change when you look at a post a trading day later. I respect your dedication, but you’re zeroing in on a direct comparison nobody is making. It’s a long post for sure and most would just skip it and go to comments but the only direct comparisons made were - neoclouds with mag7 contracts - neoclouds with healthy balance sheets - neoclouds that don’t directly have contracts with OpenAI. So just to help you again, the whole post was about credit markets, debt structure, OpenAI capex overhang, and ecosystem risk affecting the whole sector. Using 1W to 1M timeframe is to show levels neoclouds dropped from (eg. $IREN after MSFT deal) for a sector wide drop from premarket. Using different prices a trading fay later when neoclouds recovered from premarket doesn’t change or favor the thesis. It helps to read past the first sentence (I own $IREN too)

指出AI处理海量13F文件存在局限，曾尝试但结果出错。
@number1invest_ @grok 让 Grok 处理通过审查每一份 13F 文件(13F Filing)来进行的大量数据计算(13F filing)可能太多了。我记得在另一个帖子中要求它只输出一个结果，但它搞错了。 https://t.co/rP8XZNQMpX

13F多为噪音，短期下跌属宏观无差别抛售。
不，13F 文件（13F filings）很多时候只是噪音，除非是伯克希尔（Berkshire）在买入。而这些评分只是判断某只股票是否适合长期持有（例如：是否有大量长期被动基金投资者做多该股票）这一多维方法中的一个小信号。 短期内，像 $CIFR 或 $CORZ 这样的下跌是宏观因素导致的，因此这是全市场的无差别抛售。
英文原文
No, 13F filings a lot of time is just noise unless you have Berkshire buying in. And these scores are just one small signal of a multifaceted way to determine if something is a good long (eg. Do you have lots of long-passive fund investors going long on a stock) Short term on stuff like $CIFR or $CORZ drops were macro, so it’s an indiscriminate selloff across the board.

建议现金党通过卖出CSP期权以低价获取权利金。
@rioferdy838 @Mattyice112233 @Docofgothm 对于 $NBIS 和矿企，如果你是现金党，是的，请卖出接近当前行权价（如 $105）的云服务提供商(CSP)期权，因为你的目标是以最低价格被指派并获取权利金。
英文原文

投资无绝对优劣，需基于当前市值权衡风险与回报。
@Antonzeehow 其实并没有绝对的从优到劣排名。更多是基于当前信息，在风险与回报之间的权衡取舍。 别太当真，这只是我基于当前市值(Market Cap)的个人直觉。 https://t.co/RiCqPEOANm
英文原文
@Antonzeehow There's not really a best to worst. It's more of trade-offs from risk vs. reward given current information. Don't take this too seriously, but this is just my personal feeling right now given current MC's. https://t.co/RiCqPEOANm

AI工具在分析Neoclouds时存在缺陷，作者更倾向手动整合信息并采用估值建模。
我发现像 @AskPerplexity、Grok 等 AI 工具在研究 Neoclouds（新型云服务商）和每日新闻频发的板块时，结果往往极不准确。它们会遗漏大量细节，例如 $NBIS 的白皮书中有关于与 $CRWV 等对比的利用率信息，这些数据对 AI 不可见（暗示了 GPU 利用率带来的毛利率增长）。当 Meta 与 $CRWV 达成 140 亿美元交易，且上周 $AMZN、$MSFT 等发布财报显示 AI 资本支出增加时，AI 可能会忽略那些未直接提及 $NBIS 但暗示超大规模云厂商交易增加的顺风因素。或者几天前的额外降息提振了涉及债务的 Neoclouds 的前瞻性盈利。亦或是关于 Clickhouse 等子公司或投资组合公司的新信息，AI 可能无法将其串联起来。FinX 散户在将这些信息拼凑成前瞻性增长方面做得更好，鉴于 AI/Neocloud 的总可寻址市场(TAM)具有高度投机性和快速增长，很难建模。这也是我采用估值方法的原因（在我之前关于 $NBIS 如何达到 1000 亿美元市值的帖子中），但如果看 $UPWK 等更标准的业务，我的估值建模方式则不同。
英文原文
I've actually found AI tools like @AskPerplexity, Grok and others to be extremely off when looking at Neoclouds and sectors with new news every day. They miss a lot of details, eg. with $NBIS you have utilization information from Whitepapers comparing Nebius to $CRWV and others that aren't publicly viewable to AI (which insinuated growing gross margins from GPU utilization). When Meta struck a $14B deal with $CRWV and you have earnings report last week from $AMZN, $MSFT, and others you have increased capex spend into AI, and they might miss tailwinds that don't mention $NBIS directly with increased changes of more hyperscaler deals. Or when there's an additional rate cut a few days ago that boosts forward earnings especially with Neoclouds that involve debt. Or when there's new information about subsidiaries or portfolio companies like Clickhouse that AI might put 1+1 together with. FinX retail does a lot better job with piecing all this information together into forward growth and AI/Neocloud TAM is really hard to model given how speculative and rapidly growing it is. That's kinda why I go with valuation approaches (in my previous post on how you get to $100B MC for $NBIS), but if you look at $UPWK and more standard businesses. I do valuation modelling differently

批评盲目跟风，强调投资需基于实质性估值分析。
谢谢，我快速浏览了一下（未做事实核查），这是一篇关于 $NVO 的很棒的文章。 我不指望原帖作者（OP）能达到你这样的尽职调查(DD)水平，但当 OP 不断发帖称其“便宜”时，至少应给出一些实质性的解释。 4%的股息率和双位数的销售额增长，对于任何进行估值的人来说都毫无意义。 但粉丝可能只是盲目跟随，而不是基于有信息量的信息做出自己的选择。
英文原文
Thanks did a quick skim (didn’t fact check tho), that’s a great write up for $NVO. I don’t expect your level of DD from OP but at least when OP keeps posting“cheap”, at least give some substance in an explanation. 4% dividend and double digit sales growth just means absolutely jack to anyone doing valuations. But followers might just blindly follow rather than making their own choices based on informative info.

批评仅凭“便宜”而无实质分析的帖子误导粉丝。
@dividenddude 恕我直言，这类帖子基本上没有任何实质内容或分析。你昨天对 $FI 说“便宜”，现在又对 $NVO 这么说。用毫无用处的解释声称某物“便宜”，只会让粉丝盲目亏钱。
英文原文
@dividenddude With all due respect, there’s basically zero substance or analysis from these types of posts. You’ve done this with $FI yesterday saying “CHEAP” then this again with $NVO. Saying something is cheap with useless explanations is how followers end up blindly losing money.

持有ETF和LEAPS是安全的上行策略，需匹配个人风险偏好。
@WZRDtheWise @blu400_ 持有像 $META 这样的 ETF 和长期期权(LEAPS) 并没有错。这大概是最安全的上行策略，而且每个人的风险偏好都不同。

@WZRDtheWise @blu400_ There’s nothing wrong with holding ETFs and Leaps on stuff like $META. That is probably the safest upside thing to do, and everyone has different risk profiles.

博主分享通过评论和私信挖掘小盘股的研究方法。
@cmachdop 我基本上会去查评论区提到的每一个股票代码，比如 $ABAT，或者人们@我的那些。很多人也会私信我询问关于小盘股的事，我从中学到了很多。虽然不完全是那种极小盘股，但我目前正在关注 $LGN，因为它是“七巨头”（Mag7）的客户。
英文原文
@cmachdop I kind of just look up every ticker that gets mentioned on comments $ABAT or what people tag me in. Many people DM me too asking about small caps and I learn a lot there. It's not quite your extremely small cap but I'm looking at $LGN right now because of mag7 clients.

强调投资需基于可扩展基本面，建议投资者独立研究决策。
是的，你提出的观点很棒。我以量子计算股票如 $RGTI 为例，提醒在整合仓位时需谨慎，但你提到了 $FLNC。经验法则是，重要的是要知道股票定价何时由可扩展的基本面支撑。但我在此帖中并非要为任何个股树立观点，只是举例。人们应自行研究并做出自己的选择。
英文原文
Yep that's a great point you made. I gave quantum stocks like $RGTI as an example of caution if you're consolidating, but you mentioned $FLNC. Rule of thumb is that it's important to know when the pricing of a stock is backed up by scaling fundamentals. But I'm not here to make a point with any individual stocks in this post, just gave examples. People should do their research and make their own choices.

建议对$FLY进行税务亏损收割并一月后重买，以优化税务并降低杠杆风险。
所以 $FLY 在这里挺有意思，因为它处于税务亏损收割(tax harvesting)的范围内，毕竟年初至今(YTD)已下跌57%。 我喜欢它，因为它是针对2026年中型起降(medium-lift)市场的布局，并非短期持有标的。 但既然你使用了过多的杠杆(margin)，那么现在进行税务亏损收割，然后在一个月后重新买入(re-rebuy)可能是一个好主意，这样你可以在一个月后以可能相似的成本持有相同头寸，同时降低应税收益(taxable gains)。 是的，正如你所说，在更好的时机进行税务亏损收割比在下跌6.3%后立即操作更好，虽然感觉不太好，但年底(EOY)很难逆着税务亏损收割的潮流而行，我个人在交易像 $SNAP 或 $ETOR 这类股票时也总是低估这一点。
英文原文
So $FLY is a interesting one here because it's in the tax harvesting lot since it's down 57% YTD. I like it because it's a 2026 play for medium-lift, not exactly a short term hold. But since you're using too much margin, then it might be a good idea to tax harvest now then re-rebuy 1 month later, so you can lower any taxable gains while having the same position 1 month later at possibly similar costs. Yeah as you mentioned better to tax harvest on a better time rather than right after a 6.3% drop, feels bad but it's hard to go against the tax-harvesting flow EOY and I always underestimate it too personally when trading stuff like $SNAP or $ETOR.

宏观视角下，利用年底季节性、降息预期及机构资金流向，激进配置新云与AI赢家股。
宏观分析： 关注领域：资金流向 · 代理指标 · 季节性 · 仓位配置 布局： _ 新云(Neocloud)：$NBIS · $IREN · $CIFR · $DGXX 连接性(Connectivity)：$ALAB · $CRDO · $CLS 机器人(Robotics)：$KRKNF · $ONDS · $RR 国家安全(National Security)：$RKLB · $MP · $KTOS · $CCCX 能源(Energy)：$FLNC · $EOSE · $TE · $SEI 半导体(Semi)：$TSM · $AMD · $NVDA · $MU _ 第一部分 - 机构资金流向 进入10-11月，对冲基金卖出表现不佳的股票以锁定税务亏损并重新平衡仓位。 这造成了由税务亏损收割(tax-loss harvesting)带来的机械性下行压力，即轮动年内亏损股并轮动至赢家股。一旦这种抛售结束且洗售(wash sale)窗口期过期，机构和量化基金通常在12月中下旬或1月初回购这些超跌股。 上述布局展示了所有年内上涨的股票，通常你希望在年底通过收割亏损股并加仓赢家股来激进配置。 像$SNAP、$ETOR、$DRFT等可能在基本面被低估的股票，很大程度上受机构仓位配置影响。除非你想等待2-3个月并在此期间积累筹码（这也是有效策略），否则顺势而为更好。 第二部分 - 代理指标(Proxies) 新云 - 我们看到了$META与$CRWV的交易，$WULF与$GOOGL及Fluidstack的合资企业，$MSFT对OpenAI的计算需求增加等，这对整个新云板块极其看涨。因此该板块可能继续跑赢大盘。 国家安全 - 我们看到特朗普持有$MP等关键材料公司的股份，并开始关注支持更多国家安全风险，如量子计算公司$RGTI、$IONQ等。这对$RKLB等其他国家安全建设板块总体利好。 半导体 - $TSM是半导体建设和需求的最佳代理指标，其远期营收预测令人难以置信。人们常犯的错误是看$ASML的晶圆厂周期，但这并非正确的代理指标。 我们可以用$CLS作为连接性的代理指标，或用$BE的财报作为能源的代理指标等。 但通常，你可以通过该领域的其他公司很好地判断哪个板块正在跑赢或可能表现良好。 第三部分 - 季节性 11月和12月是股市表现最强的月份。 这更多是心理层面的，因为情绪因素。但也部分出于机械性原因，因为基金在10月进行税务亏损收割重新部署现金后，“追逐业绩”以锁定年度收益。 第四部分 - 仓位配置 这完全取决于你自身的风险水平。例如，对于较小的$10万投资组合，你可以像这样激进配置： 25% $NBIS, 10% $IREN, 10% $ALAB, 10% $CRDO, 5% $KRKNF, 5% $FLNC, 5% $TSM看涨期权, 20% 杂项或低贝塔(如$HOOD), 10% 现金。 如果你想做“赌徒”(degen)，现在可能是最好的时机。我之前举过一个ETF的例子说明如何配置，但我通常不建议将整个投资组合集中在单只股票上。 还有其他未提及的板块如金融科技/电商($HOOD, $SOFI, $DLO, $SEA)等，你可以自行替换。 第五部分 - 宏观 人们担心AI泡沫，但泡沫通常在美联储收紧时破裂，我们最近已在许多泡沫股中看到修正。但现在我们将迎来另外两次降息和政府重新开放（这是一个奇怪的催化剂，但确实存在）。 根据Polymarket，有86%的概率再降息两次，这很疯狂。随着三次降息，成长股和小盘股往往因廉价资金和债务缓解激发风险偏好而飙升。大量流动性最终将流入成长股和小盘股。 _ 这只是总体趋势，你可以选择自己的股票篮子，或任何你认为不错的。我个人对新云、AI建设最看涨，并更倾向于非对称(asymmetrical)选择，但各凭喜好（例如人们在能源/机器人或金融科技上有大量仓位）。 另需注意，即使某只股票如$RGTI上涨500%，也要确保其上涨有基本面支撑（如新云、远期营收）。 但总体而言，如果你只能记住一点，那就是在两次降息、年底季节性和向赢家股集中配置时激进出击，这是前所未有的最佳时机。
英文原文
Macro Analysis: Focus Areas: Flows · Proxies · Seasonality · Positioning Setup : _ Neocloud: $NBIS · $IREN · $CIFR · $DGXX Connectivity: $ALAB · $CRDO · $CLS Robotics: $KRKNF · $ONDS · $RR National Security: $RKLB · $MP · $KTOS · $CCCX Energy: $FLNC · $EOSE · $TE · $SEI Semi: $TSM · $AMD · $NVDA · $MU _ Part 1 - Institutional Flows Into October–November, hedge funds sell underperformers to lock in tax losses and rebalance positions. This creates mechanical downside pressure from tax-loss harvesting by rotating losers YTD and rotating into winners. Once this selling ends and wash sale windows expire, institutions and quants often buy back these oversold names in uually mid tolate Dec or early January. The setup above shows every stock that up YTD, usually you want to position aggressively into these EOY by tax-harvesting losers and scaling into positions that win. Stocks like $SNAP, $ETOR, $DRFT, and others that might be undervalued fundamentally is largely affected by institutional positioning. It's better to go with the flow rather than fight against it unless you want to wait out 2-3 months and accumulate during this time (which is a valid strategy as well). Part 2 - Proxies Neocloud - We've seen $META x $CRWV deal, $WULF x $GOOGL x Fluidstack JV, $MSFT having more compute demand from OpenAI, and others, which is extremely bullish for the whole Neocloud sector. So sector will likely continue to outperform. National Security - We've seen Trump take stakes into critical material companies like $MP and start looking into backing more national security risks such as quantum names like $RGTI, $IONQ, and others. This is generally positive for other names like $RKLB or other national security buildout across the board. Semi - $TSM is the best proxy for semiconductor buildout and demand and their forward revenue projections are absolutely insane. People make the mistake of looking at Fab cycles from $ASML but it's not the right proxy. We can go on with $CLS as a proxy for connectivity or $BE earnings for energy, etc. But generally, you can get a good idea on what sector is outperforming or is likely to do well based on other companies in the area. Part 3- Seasonality November and December are the strongest months for equities. This one is more psychological because of sentiment. But also partly mechanical because funds “chase performance” to lock in annual gains after they redeploy cash from tax loss harvesting in October. Part 4 - Positioning This is purely based on your own risk level. For example, with a smaller $100k portfolio you can be fine positioning aggressively like: 25% $NBIS, 10% $IREN, 10% $ALAB, 10% $CRDO 5% KRKNF, 5% FLNC, 5% TSM calls, 20% misc or low beta (eg. $HOOD), 10% cash. If you want to be a degen, now is probably the best time to do so though. I gave an example ETF earlier on how you can position but I typically don't recommend concentrating your whole portfolio into single stocks. There are other segments I didn't mention like Fintech/Commerce ( $HOOD, $SOFI, $DLO, $SEA) and so on but you can plug and play. Part 5 - Macro People worry about AI bubbles, but bubbles pop when Federal Reserve tightens, and we recently got a correction in a lot of bubbly names. But now we're going into 2 more rate cuts and government re-opening (which is such a weird catalyst but it is one). We have a 86% chance of 2 more rate cuts which is insane (as per Polymarket). And, with a triple rate cut, growth and small caps tend to surge as cheaper money and debt easing spark risk appetite. Floods of liquidity will eventually flow into growth stocks and small caps. _ This is just the general trend, you can pick your own basket of stocks, or whatever you feel is great. I'm personally the most bullish on Neoclouds, AI buildout and positioned more heavily toward asymmetrical picks but to each their own (eg. people have large positioning in energy/robotics, or fintech) Also something to note is that even if something goes up 500% like $RGTI, make sure the rise backed by fundamentals (eg. Neoclouds, forward revenue) But generally if you had to take one piece away, being aggressive into two more rate cuts, end of year seasonality, and consolidating into winners is the best time ever for it.

根据交易策略和标的波动性选择券商平台
我在盈透证券(IBKR)之外也使用Robinhood和Charles Schwab。使用多个平台没问题。 但如果你大量交易期权，建议转向$IBKR或Fidelity，因为两者的执行质量极佳。在波动性更高的情况下，$IBKR可能略胜Fidelity。 不过情况很微妙。如果买卖价差很低（如$MSFT或$SPY），$HOOD优于其他平台，你实际上能省钱。 如果你在$CIFR或高隐含波动率(IV)股票上卖出期权，价差通常大得多，仅因糟糕的成交执行（例如交易6万美元期权）就可能损失数千美元，此时你最好从$HOOD转移。 如果是长期投资且不加杠杆，平台选择其实无所谓。如果是长期投资且使用股票保证金，$IBKR或Robinhood很棒，因为保证金利率较低，而Schwab/Fidelity较高。 总之，这取决于你的具体目标和持仓股票，情况相当微妙。
英文原文
I use Robinhood and Charles Schwab too on top of IBKR. It's fine to use multiple. But if you're doing a ton of options it's worth going to $IBKR or Fidelity since both of them have great execution. IBKR probably tops out Fidelity when it comes to more volatility. It's nuanced though. $HOOD beats other platforms if the spread is low like $MSFT or $SPY and you'll actually save money. If you're selling options on $CIFR or higher IV stocks, the spread is likely to be much much higher and you can lose thousands of dollars (if you trade with $60k in options for example) just based on bad fills and completely you're better off moving from $HOOD. If you're long term investing, no margin, doesn't really matter what platform you go. If you're long term investing margin with shares, IBKR or Robinhood are great cause margin rates are low, while Schwab/Fidelity are higher. Again it's kinda nuanced depending on what exactly you're aiming to do, what stocks you have.

博主澄清其AI、半导体及金融背景，强调论点应独立于身份。
我本不打算回复，但鉴于其他评论试图用“年初至今(YTD)表现”这种诉诸权威的方式来否定我的论点。我曾是AI领域的研究科学家，在《自然》等期刊发表过几篇论文。我在半导体领域也拥有专利。我现在经营一家金融科技(fintech)公司，所以很擅长数据计算。顺便提一下 @mithrilcompute，前几天我和他们的CEO喝咖啡聊过，所以与业内人士的日常交流也很有帮助。这三个不同领域的背景有助于我理解数据中心(data center)领域。如果你看过我的其他评论，我会始终承认自己缺乏领域知识，并避免给出方向性观点。此外，论点应独立成立，而非基于发言人的身份。
英文原文
I wasn’t going to reply to this but just because other comments tried appealing to authority like YTD performance to invalidate the thesis. I was a research scientist in AI with a few published papers in journals like Nature. I also have patents in the semiconductor space. I now run a fintech company, so im decent with number crunching. Just a quick shoutout to @mithrilcompute, talked with their CEO the other day over coffee, so just daily chats with people in the space help a lot too. So all three different domains helps a bit with understanding data center space. If you read my other comments, I’ll always acknowledge if I don’t have domain knowledge and refrain from giving directional posts. Also arguments should stand on their own, not based on who it came from.

提醒市场通常提前两周半将事件预期计入价格。
@basanthgowda @DeepValueBagger 我并不是在建议采取任何行动，只是发出一个警告信息。 但通常情况下，市场会在事件发生前约两周半开始更多地将其计入价格（priced in）。

@basanthgowda @DeepValueBagger I’m not saying to do anything, just giving a warning message. But generally it starts getting priced in more 2 1/2 weekish before the event

演示极度保守的估值方法，通过大幅折价计算持仓净值。
$58.8亿（现金）+ $26.8亿（投资组合公司股权，但我认为被低估了）+ 实物资产：约$20亿 = 105.6亿。 然后你对实物资产/投资组合股权打约6折，因为公司交易价格并不真的与净资产值(NAV) 1:1挂钩 = 持仓价值28.08亿 然后对现金打一些折扣，但幅度小得多，因为现金就是现金 = $58.8亿中的约43亿 28 + 43 = ~71（在极度保守的一端）
英文原文
$5.88B (cash) + $2.68B (equity in portfolio companies, but undervalued it) + Physical Assets: ~$2B = 10.56B. Then you slash ~40% off physical assets/portfolio equity because companies don't really trade 1:1 with NAV = 2.808B in holdings Then discount some cash but a lot less since cash is just cash = 4.3b-ish of $5.88B 2.8 + 4.3 = ~7.1 (on the hyper conservative end)

公开披露往往伴随股价高估，非买入信号，应提前独立决策。
@jeanli28 @itsthesquonky 当像 $OPEN 这样被披露时，股价可能已经涨得太多了。这并不是一个好的买入信号，人们应该在任何大幅上涨之前做出自己的决定，所以这没什么值得庆祝的，尤其是 Jane Street 哈哈。
英文原文
@jeanli28 @itsthesquonky The moment it’s disclosed like $OPEN it’s probably run up too much. Its not a good buy signal, people should be making their own decisions before any major run up, so its not something to be celebrating, especially Jane street lol

反驳“当前价格已充分反映”观点，强调市场低效带来的套利机会。
他们什么都没搞对。“当前价格已充分反映。”这完全是错的。 他在寻找超额收益的方向上是对的，但想用一些Instagram风格的励志语录。 如果当前价格总是被正确定价，就没人能通过利用市场低效来赚钱了。 不久前，由于市场未能正确定价，套利 $BULL 股票与认股权证就是白捡的钱。或者像 $UPWK 这样大量被错估的股票，以低于6.5倍的市盈率交易，却拥有庞大的现金资产负债表和增长。
英文原文
They didn't nail anything. "The present is already priced." This is literally wrong. He's correct directionally finding alpha, but wanted to use some Instagram style inspirational quote. If the present were always correctly priced, nobody would make money exploiting market inefficiencies. It was free money arbitraging $BULL shares vs. warrants not too long ago due to markets not pricing things in correctly. Or tons of misvalued equities like $UPWK trading way trading under 6.5 P/E with large cash balance sheets and growth.

AI非泡沫因有收入支撑，量子核能属投机，降息后或现狂热。
@accounting_ds @soulbiri1 目前肯定还不是人工智能(AI)的狂热(euphoria)或泡沫，因为大多数公司都有远期收入支撑。量子/核能目前是一个投机性泡沫，关键矿产(critical minerals)可能也是。我们可能在三次降息后才会看到狂热的真正含义。
英文原文
@accounting_ds @soulbiri1 It’s definitely not euphoria in AI or a bubble yet since most are backed by forward revenue. Quantum/nuclear is a speculative bubble to right now, possibly critical minerals. We might see the true meaning of euphoria after triple rate cut

建议优先使用融资而非2倍杠杆ETF，因后者存在波动率损耗。
不，如果你可以使用融资(Margin)或期权(Options)，使用2倍杠杆ETF几乎没有任何好处。如果你想要相同的敞口，直接使用融资买入普通股即可。2倍杠杆ETF存在波动率损耗(Volatility Decay)，因此不适合长期持有。 也许如果你无法在IRA中使用融资，或者你的维持保证金要求(Margin Maintenance)极高（例如80%），那么使用它是可以理解的。
英文原文
No, there's almost no benefit for 2x leveraged etfs if you have margin or options. Just go with common stock on margin if you want the same exposure. 2x leveraged ETFs have volatility decay so it's not good to hold. Maybe if you cant have margin in an ira or something and have super high margin maintenance like 80% it's understandable.
