Having tactically traded through the 1998 Russian crisis and LTCM collapse, the dot-com bubble and crash, the 2007–09 financial crisis, the COVID shock, and everything since—I can’t stress this enough:
The best countertrend setups don’t come from just buying dips. They come after failed breakdowns or clear bullish divergences. Without those signals, you’re simply buying weakness and hoping for a bounce.

The most exciting time to be alive in human history.
AI-driven progress is convex, not linear, and healthcare is next.
The edge: stay healthy. Stay alive. Longevity is about to expand.
Investors have heard the advice so often it sounds like common sense: start with a small position, see if you’re right, and add once the trade proves itself. It feels careful, but gets the order wrong.

If true, some computer systems that plan things (delivery routes, factory schedules, chip designs, certain AI searches) might eventually get a little faster than experts thought possible. That could mean slightly better logistics, cheaper computing for hard problems, or new algorithms showing up in software years from now. Probably won’t change your phone, Netflix, or everyday apps anytime soon, and it doesn’t give anyone a magic button to solve hard problems instantly.

The $80B headline is mostly accounting noise. The real question is why investors are willing to mark Anthropic dramatically higher while the business is still losing money. That says far more about what the market is willing to pay for future AI dominance than it does about today’s economics.
Amazing that you can lose $80B in 6 months and see your valuation triple
