Harvard needs 8% return every year just to keep the lights on. 5% spending plus 3% inflation. Miss that number and buildings stop, professors leave, research dies.

40% of the operating budget comes from one portfolio. Not tuition. Not grants. One fund.

Jake Xia manages that fund's public markets. He also teaches the math behind it at MIT for free. One of the top five most-watched courses on OpenCourseWare. Millions of views. Almost nobody changed how they invest.

Every year he hands students a blank page. Build a portfolio. No rules. Someone writes 100% Apple. Someone writes rare coins. Confident picks. Same blind spot, every time.

Not one student asks the only question that matters: how much goes in each position. They all pick what to buy. Nobody sizes it.

Sizing is the entire job. The answer won the Nobel Prize. It's called the efficient frontier. Xia draws it on the board in under a minute.

Five equations sit underneath it. Compound growth. Present value. The geometric mean. The Rule of 72. Real return. All older than any bank on earth. All fit on a napkin. None behind a paywall.

A "guaranteed 5% bond" during 4% inflation is a 1% return. The industry doesn't hide this. It just hopes you never run the equation yourself.

The lecture is free. The napkin is free. The only thing that costs anything is not knowing.

@DavidSacks Amen.

[Bill Ackman @BillAckman]

I am going to formally endorse @realDonaldTrump. I came to this decision some time ago as many @X followers have already understood from my supportive posts of Trump and my criticisms of @POTUS Biden.

The reason why I have not yet formally done so is that I want to explain my thinking in detail and address the arguments put forth by others against Trump. I want to make the case thoughtfully and convincingly.

Today, when one announces an intention to support Trump, Biden supporters who know me tend to assume that I have lost it. I assure you that I have made this decision carefully, rationally, and by relying on as much empirical data as possible.

It will take a long-form post to explain my thinking. I might even break my own record. I just haven’t had the time nor felt the urgency to write the post as we are still a few months from the election.

I am explaining my conclusion now in response to many questions I have received on the topic so that I am formally on the record.

You of course don’t need to care about my opinion so feel free not to read my post when it appears. That said, I believe the upcoming presidential election is one of the most consequential elections in my lifetime so I am taking the proper time to articulate observations that I will share widely and for which I assume an important responsibility.

I have had the benefit of spending a few hours recently with President Trump so I will have some first hand observations to share.

As always, I respect everyone’s right to form and share their own views on this important topic.

Please keep an open mind on the upcoming presidential election. Bear in mind that your views on Trump have likely been dramatically affected if you have sourced your info on Trump from mainstream media or friends or family who have relied on mainstream media as a source of knowledge.

We have all recently learned in the starkest manner (the debate) how we cannot rely on the MSM as our source of truth on the ultimate political question.

Remember, media organizations are like sports teams that run plays chosen by their owners and executed by the coaches they hire. They are not unbiased arbiters of the truth.

I fully endorse President Trump and hope for his rapid recovery

[Charlie Kirk @charliekirk11]

As blood drips off his face after what appears to be an assassination attempt, President Trump pumps his fist defiantly in the air as Secret Service escorts him off stage.
