Why China will win AI in one chart. Power hungry Nvidia chips are not the way forward for the U.S. It is not just the total power advantage. It is the slope.

In 2000, I was short Amazon and called the top in the market, as well as the coming rally in Old Economy stocks. I believed in that so much I left medicine July of 2020 and went long 13 Old Economy stocks such as Paccar, Ross Stores, and Clayton Homes when Scion Capital launched October 2000.

I gave an interview to Barron’s in late June, 2021 honestly trying to warn people about an imminent meme stock collapse. Barron’s published the interview July 2021, near the top for AMC. Within a month or two all were crashing and by year end 2023, they had all collapsed.

@Ricardo_Celini I believe Buffett was also responding to the valuation of Microsoft and other big tech of the time. He was getting beaten up in the press about not being in this stuff. ANd he gave a very nuanced answer that was not anti-tech at all.

The first half of 2021, I made some noise and news on a number of bearish callls - TSLA, GME, Bitcoin, Robinhood, the Nasdaq 100. MANY, including journalists like Jonathan Levin and Shuli Ren @Bloomberg cite these specific examples of how wrong I have been again and again to invalidate what I am saying today, but history proves differently. This is roughly what they did from that early 2021 time to early 2023, when in the middle of the banking crisis I said I was not seeing true danger and it could resolve quickly. To look back at those calls 5, 10, years later - any short call - is ridiculous. You really think any short seller holds those positions for 5, 10 years?

Everyone that knows anything knows this. OpenAI is the next Netscape, doomed and hemorrhaging cash, Microsoft is trying to keep it afloat while keeping it off balance sheet and sucking out the IP. So why do they keep getting funded? The whole industry NEEDS a 500 billion IPO ASAP.

I never said I was short $TSLA in my SS post. @fortune @bloomberg The article also reports on an older $500 million bet. No, it was $5 million. 13Fs and journalists… The full text of what I wrote: β€œOutgrowing dilution, for purposes of achieving maximum present value for an enterprise, is not easy. Tesla dilutes its shareholders at about 3.6% per year, with no buybacks. The chart above shows the kind of present value destruction that this level of dilution can impart. With recent news of Elon Musk’s $1 trillion dollar pay package, dilution is certain to continue. Tesla’s market capitalization is ridiculously overvalued today and has been for a good long time. [As an aside, the Elon cult was all-in on electric cars until competition showed up, then all-in on autonomous driving until competition showed up, and now is all-in on robots – until competition shows up.] Another beauty is Palantir, which has been diluting shareholders at about a 4.6% annual rate despite buybacks. Palantir has no earnings after adjusting for stock-based compensation. Palantir has the distinction of being the first billionaire:revenue ratio greater than one that I have seen. Five billionaires due to stock ownership, and less than four billion in annual revenue.”

Since the beginning of 2018, NVDA earned about $205B net income and $188B free cash flow, assuming all cap ex was growth cap ex. SBC amounted to $20.5B. But it bought back $112.5B worth of stock and there are 47 million MORE shares outstanding. The true cost of that SBC dilution was $112.5B, reducing owner's earnings by 50%. /rant
