不到 1000 万美金，你根本不需要选股 散户有一个挺普遍的误区：账户里有几万几十万美金，就开始琢磨怎么在二十只股票之间做配置。 我的看法很直接。1000万美金以内，选股这件事对你没有价值。要么全买指数ETF，要么就买当下最主流、流动性最好的那几只。中间那些花大量时间挖出来的「性价比标的」，反而是最没必要的部分。 因为分散持仓从来不是一个赚钱手段，它是机构的合规产物。 基金有受托责任，有单一持仓上限，有风控条款，有季度赎回压力。一只票拿到组合的15%，风控就该找你谈话了。它们不是不想集中，是不被允许集中。而你没有出资人，没有合规部，没有人在季度末拿回撤考核你。把机构的约束条件当成投资智慧抄过来，等于自愿戴上一副别人被迫戴的镣铐。 规模这一层更实际。 机构真正的难处是建仓本身就在推价格，清仓本身就在砸坑。几百亿的基金想买一只中盘股，得分几周慢慢吸，卖的时候还要担心那根大阴线是自己画出来的。所以它必须把钱摊到几十上百个标的上。 1000万美金放在主流大票里是什么概念？开盘一分钟进出，盘口不会有任何反应。冲击成本这个问题对你不存在。既然约束不存在，为这个约束设计的解决方案自然也不需要。 最后一点是最多人栽的地方：一个人管不了那么多仓位。 持仓超过十只，你不可能对每只都保持真实认知。财报看不完，消息跟不上，某只跌了20%你不知道该加还是该砍，涨上去也说不清该不该走。手里握的最后是一堆自己不了解的代码。 而且这种分散往往是假的。二十只票里可能十八只跑的是同一个beta，你以为在对冲风险，其实只是把同一个赌注拆成二十份下，还多付了二十倍的注意力。 所以要么承认自己不做研究，SPY、QQQ买了躺着；要么就集中在你真看得懂、成交量足够大的少数几只上。 稀缺的从来不是标的，是你能持续跟踪的注意力。 #美股# #投资理财# #ETF# #指数基金# #仓位管理#

Andrew Ross Sorkin today on his @Starlink experience on United Airlines: "Amazing. I wonder what it's going to mean for other airlines . If you were traveling from NY to LA for the next couple years, if you had a choice between Starlink and no Starlink, you'd choose Starlink. I think this is going to be huge for them."

Standing in front of the Burj Khalifa again. Goosebumps. Around three years ago I was here talking to a crypto bro based in the UAE. He told me most of his friends use @TrustWallet. I said that was impossible. It lacked this feature, that chain, that polish. He just smiled and said, “That’s what I see people using.” Coming back to the same place, I can only laugh at my own naivety. Trust Wallet is more performant now. The UX is better. We support more chains and features than ever. But that’s not why people stay. They stay because they trust. They trust the brand. They trust self-custody. They trust that the team will do right by them. Features can be copied. Performance can be improved. Trust takes years to build. We’re nine years in. Still early. Still entrusted by millions. What we carry forward isn’t just a product. It’s the trust of the people who chose us. It’s always Day 1. Thank you for your trust.

Sam Altman asked Elon Musk what he'd do if he were 22 again. Not "build Tesla." Not "start a rocket company." Two words: be useful That's the whole framework. It sits on two questions almost nobody asks themselves. How much better is your solution than what already exists? How many people can it actually help? Multiply the two. That's your real impact. Every company that has ever changed the planet started by solving a useful problem for a specific group. Nobody who set out to "change the world" ever did. The companies that transformed anything started by making one boring, useful thing 10x better. 22-year-olds looking for a moonshot miss the actual moonshot sitting in the boring problem next to them. Be useful. Ship it to a small group. See if they can't live without it. Repeat. What's the most important problem you think still doesn't have a real solution? Drop it in the replies.
