说人们买苹果设备是为了工作和学校，但对方看的是三星衬底良率如何支撑 capex。
@jukan05 大多数人买苹果设备是为了日常工作或者上学。 @jukan05 买它，是因为三星 8.6G 衬底的良率足以支撑他们的 CapEx。
英文原文
@jukan05 Most people are buying Apple devices for daily work or school. @jukan05 is buying it because Samsung 8.6G substrate yields justifies their capex.

列出 AI Displacement 等权组合年初至今回报，认为自己无意中做出了一个很强的 ETF。
我看了一下书签数量，才意识到： 我低调地搞出了一个很能打的 ETF？ AI Displacement 等权组合年初至今： $AXTI：+191.53% $AAOI：+144.47% $SNDK：+140.38% $SOI：+114.3% $LITE：+61.22% $AEHR：+60.97% $BE：+56.56% $VRT：+47.42% Samsung：+42.8% $TER：+37.99% $MU：+35.1% SK 海力士：+34.42% $NBIS：+25.57% $COHR：+24.92% Mediatek：+17.01% $INTC：+16.23% $ASML：+15.63% Advantest：+11.78% $TSM：+5.85% $COPX：+4.56% $TSEM：+2.44% $MRVL：-1.71% $NVDA：-4.55% $AVGO：-7.32% 这只是我脑子里第一时间想到的名字。 我个人持有其中很多，也没持有另外一些，比如 $NVDA 或 $BE，但我还是把它们放进来了。 不过老实说，如果我现在不是在主动管理仓位集中度，我会很愿意把这些名字等权配置。 我预计 AI Displacement ETF 还会继续上涨： 因为这些公司都是人工智能扩展算力和推理最主要的受益者。

I realized by the amount of bookmarks. I lowkey dropped a banger ETF? AI Displacement Equal Weighted YTD: $AXTI: +191.53% $AAOI: +144.47% $SNDK: +140.38% $SOI: +114.3% $LITE: +61.22% $AEHR: +60.97% $BE: +56.56% $VRT: +47.42% Samsung: +42.8% $TER: +37.99% $MU: +35.1% Sk Hynix: +34.42% $NBIS: +25.57% $COHR: +24.92% Mediatek: +17.01% $INTC: +16.23% $ASML: +15.63% Advantest: +11.78% $TSM: +5.85% $COPX: +4.56% $TSEM: +2.44% $MRVL: -1.71% $NVDA: -4.55% $AVGO: -7.32% These are just the first names that came to my head. I own a lot of these personally (and don't own others like $NVDA or $BE ) but included them anyway. But honestly, I'd be happy to equal weight all these names if I weren't actively managing my portfolio concentrations. I expect the AI Displacement ETF to keep rising: As they're the largest beneficiaries of scaling compute and inference for artificial intelligence.

EWY 的 IV 交易成功后，自己转而看多韩国内存股，认为利润会压过宏观恐慌。
EWY 的 IV 交易是成功的。韩国指数的隐含波动率从 32% IV 上升到了 46-48%。 现在它更像是对 SK 海力士 / 三星内存的方向性做多。 Q1 NAND 价格上调了 100%+，三星据说 Q2 又再提了 100%+。DRAM 价格也远远超出预期。 氦气 / 石油 / LNG 的担忧目前被夸大了，所以我还会继续看多韩国内存板块。 经营利润最终会压过任何宏观恐慌。
英文原文
IV $EWY trade was successful. Volatility of the Korean Index went from 32% IV -> 46-48%. Now it's more of a directional long on memory from SK Hynix/Sasmung. NAND prices hiked up 100%+ Q1 and Samsung reportedly jacked up 100%+ again Q2. DRAM prices also hiked way past expectations. Helium/Oil/LNG fears are overblown currently so I'm staying long on Korean memory sector. Operational income should blow away any macro fears.
