· 方法论
如果你想找多头想法，2026年下半年有四个关键主题： 1. CPO，我最喜欢的主题，没有之一。我无法强调市场对它有多误解。 我在硅谷聊过的每个人现在都在私下资助光学初创公司，这是未来的重大信号。 2. 800VDC 功率半导体。我认为其他分析师某种程度上说服了我。 我曾小仓位持有 $NVTS，但令我惊讶的是它几乎翻倍了。进一步研究后，这在“哪些玩家变重要”上是一次相当剧烈的转变。 3. 物理 AI、人形机器人/机器人。你知道 $VPG 基本涨了三倍，我一直在找其他可做多玩家。 最有意思的下游多在私营部门，然后零部件主要在中国/日本。 4. 也许玻璃基板/先进封装仍然有机会，例如 $LPK。由于很多存储玩家最近已经重估，存储在列表中往后排了，不过小众 HBM4 玩家仍有很多机会。
Four critical themes for h2 2026 if you want long ideas: 1. CPO, #1 #1 #1 #1 favorite theme. I cannot stress how much markets misunderstand this. Everyone I've talked in SV are privately funding optical startups right now and it's a big signal of what's to come. 2. 800 VDC power semis. I think other analysts kinda convinced me on this. I was in $NVTS for a tiny bit, low concentration. But this almost doubled to my surprise. But after doing more research, it's a pretty seismic shift in terms of what players become important 3. Physical AI Humanoids/Robotics. As you know $VPG basically tripled, and there's a lot of other players I've been trying to find longs on. Most downstream of interest are private sector... Then components are mainly in China/Japan. 4. Maybe Glass Substrate / advanced packaging stuff still eg. $LPK. Memory got pushed down on the list given how much players have re-rated recently, lot of opportunity still with niche hbm4 players.
