The guy I used to work with (I’ll call him “Q”) who shorted $TSLA at $600 in Dec called me today:

Q: Why is $TSLA up 6% on no news?

GB: Because it was down 8% yesterday on no news - unless you call a 10 bp rise in treasury yields and $BTC collapsing news. You still short?


2/ Q: Of course I’m still short. It’s up another 30% since we talked two weeks ago. It’s all mo’.

GB: $TSLA MIC Y has a 4 mo wait. It’s entering India. Analysts are playing leapfrog raising PTs. Active mgrs have to own it or get fired. It’s cheap at 80x 2022 EPS vs 55% growth.

3/ Q: Your earnings estimates are like twice consensus.

GB: The Street’s been wrong on $TSLA forever. Why do you listen to them? You really shouldn’t be short going into Biden’s inaugural speech and the FY’21 volume guide at the end of Jan. You’re going to get run over.

4/ Q: Whatever.

GB: Did you rent a Tesla for a week like I told you?

Q: No. You know I don’t drive.

GB: Did you build a $TSLA 5-yr volume, earnings, cash flow model?

Q: No. No one can forecast out 5 years.

GB: Did you talk to any Audi or BMW dealers? Or Tesla owners?

5/ Q: I don’t have time for that.

GB: Q, you haven’t done any real research. $TSLA ‘s up 40% since you shorted it. Maybe you should figure out why it keeps going up.

Q: It keeps going up because people like you are pumping it.

GB: You’re giving people like me too much credit.

This is personal for a lot of people. We've never seen anything like this.

These aren't just random comments on the internet, community is meaningful, this is a person standing up in a stadium of millions of people they consider allies/friends/confidants speaking their painful truth and getting a a roar of applause and cheers and support.


This is going to be in textbooks one day
1/ I love learning about the markets. There are some brilliant people I’ve found on Twitter who have provided great insights (among others):

@JeffSnider_AIP
@LynAldenContact
@LukeGromen

But this thread is (mostly) about @profplum99

2/ Mike has an encyclopedic knowledge of market history. This interview by @DiMartinoBooth (who I also have a lot of respect for) puts that on clear display.

Mike’s explanation of passive investing and its effects on the markets was eye-opening.

3/ According to research conducted by Anadu et al for the Federal Reserve Bank of Boston, passive funds made up 48% of US equity assets under management in March 2020. That number was just 14% in 2005. Meaning 8.6% annualized growth over 15

4/ Per Mike, “passive funds have this really simple algorithm: if you give me cash, I buy.” No fundamental valuation, just buying the current market-weighted index, which means a stock gets greater representation in your fund the higher its current market value.

5/ Employers and pension fund managers are predictably contributing to IRAs through fixed salary percentages on a monthly basis. And passive funds typically hold tens of basis points of cash on the sidelines because, per Mike, “it’s toxic to their business model.”
