Heard from LPs this week: The past 9 months have felt like groundhog's day - a very small set of deals dominating all LP convos. The fever pitch to access rounds of OpenAI and Anthropic by LPs (and even GPs calling us) at times - has reached levels I've never seen...

Joel Greenblatt compounded at 49% (!) from 1985 to 2005. And the best thing, he taught a Columbia Class on how to do it. Here are 6 Investing Gems from his Columbia Classnotes (+Free PDF)👇🏼 1. Don‘t do Portfolio Management If you think like a portfolio manager, you cannot simultaneously behave like an owner. But portfolio managers research stocks. Owners research businesses. And that’s what we try to do. Research and buy businesses. 2. Management vs. Incentives For 90% of investors, getting a genuine and honest picture of the management is impossible. Instead, look at the incentive structure for the management. Are they incentivized to add value to the company? If so, they will. If not, they won’t… 3. All about Valuation In the end, it’s all about valuation. Do good valuation work, and you’ll make good investments. There’s lots of noise in finance and investing. But that’s not what causes superior returns. Find the context/story others cannot see, and you’ll do good. 4. Leverage & Patience If you own a concentrated portfolio, leverage is far more dangerous. It’ll wipe you out in downturns that ALWAYS occur sooner or later. Have patience and trust in your decisions, and there’s no need for leverage. 5. What’s your limit? Most investors fail to see their boundaries. There are so many names and “opportunities” thrown at you that it’s tempting to fall for them. But what companies do you actually understand? For most of us, that will be a very limited amount. 6. What’s a good Business It’s always: “Buy a good business at a fair price.” But what is a good business? This is Greenblatt’s criteria: You can get the PDF of all Class Notes here: https://t.co/ccHq7Eo4Bz Before you go there, please Like and Retweet this Thread. Thanks a lot!
