Lululemon’s North American sales, margins and legging demand are falling as Alo and Vuori gain share, leaving its brand moat and depressed valuation in question.

I privately told a few fund managers I respect these investing themes/theses privately: "AI is going to drive far more medical/biotech research in pursuit of age reversal technologies than we had before. In fact, at least a couple of these are reasonably likely to be the most valuable companies on the planet in 10-20 years." and related, "Many of the old medical research companies are dinosaurs, since their tech will not keep up with the new age of AI driven medical research." I told them this at the start of 2025, and for example mentioned they avoid shorting $ARKG type stocks. I could tell they thought I was completely retarded, out of my mind, etc. A couple thoughts: 1. I bet those people don't think the idea is stupid at all today. and 2. Having a thesis that seems insane but is often wrong is *awesome*. It's a heads you win, tails you lose nothing situation. Besides $MEDP long, I didn't really know how to play the idea other than avoiding a bunch of shorts. These are theses I still very much believe today, and still today I don't see people talking about them.
