@_gg_23 Tight stop losses, some use of technicals, and picking extremes; I have never been blown up in a short. Tesla I shorted for a long time as it went up a ton, but I did not lose money on it. Not a big winner but not a loser.

This is how most people misunderstand bears. They forget that I used the internet from its inception, launched my business from a web site in 1996, was one of the early Amazon resellers, and still called out the internet bubble publicly and shorted Amazon. Most people think in three dimensions or less. Bears think in six.

“Cheap land and cheap power put data centers in the high water-stress areas,” says Matthew Pine, chief executive of U.S. water-technology giant Xylem, which supplies utilities across the country. Unfortunately, most existing data centers use evaporative cooling systems that are energy-efficient but water-hungry, according to data from the 2024 Lawrence Berkeley report. Experts say retrofitting those could be prohibitively expensive.

Wrong direction. This is like Nordstrom’s opening up Nordstrom’s Rack. But Neiman Marcus opens up Neiman Marcus Rack, Bloomingdale’s opens up Bloomingdale’s Rack, Dillard’s opened up Dillard’s rack. In the end all it proves is there are too many clothes for sale. Meta pops 9% as company makes cloud push to sell excess AI compute power capacity https://t.co/GlHKTs0QN5

UAA was never a good business. They had some marketing success early but never could really translate to a good business. LULU has been riding leggings for literally 2 decades, across many generations of young ones. The stock is the best performing clothing stock of the last 15 years even after the drop

A stock falls from 100 to 10. That's a 90% decline. The investor buys in at 10 because it is indeed worth 30. But it has fallen so much it has become detached from the underlying business and so falls to 5.. The value investor is down 50%. Which isn't as bad as 90%, but is still 50 effing percent. The value investor could have sold at 8, and limited the loss. 10 years later the stock is at $30. While said nvestor gies to medical school and finsihes residency to become a surgeon. That's a six times return in 10 years. About 20% per year. Wait, is it not only a triple? No, because the investor could have sold at 5 like just about everyone else did, but did not. What I describe here is almost exactly WBD. And it didn't take 10 years, because it usually doesn't.
