📈 Index Investing & Position Sizing

S&P 500 and Nasdaq can compound long term because they are built from a broad basket of quality U.S. companies. That is why they work as high-conviction, low-maintenance DCA vehicles rather than short-term trading chips. 1
TSLA: heavy position does not mean all-in. If the stock really runs several-fold, the overweight slice is enough to capture meaningful upside. No need to max out risk just to avoid FOMO. 2

opus 4.8 felt explosive in the first half hour after release, with writing, coding, and critical thinking close to the 4.6 experience. But quality faded hard over the weekend: Saturday started showing ChatGPT-style canned language, and by Sunday it was missing basic questions. The instability itself is the red flag. 3

Micron: the whole bull/bear setup is pinned to one number — Wall Street expects 2028 EPS to decline 8%. That is why, even after the stock has gone 10x, forward PE still sits in single digits. If the late-June earnings report proves 2028 is not the cycle peak, even with only mild growth, the “cyclical discount” can break. A re-rate to 15x PE or even 20x+ becomes possible, leaving room for another double from what already looks like an elevated price. 4
NVDA: flat price action is not the same as no progress. The stock was around 210 last October and is still around 210, but valuation compressed from 55x PE to 22x PE. Complaining about “no gains” after chasing the prior top is an emotion problem, not a stock problem. 5
MRVL: insider buying near the lows matters. Insiders sell for many reasons, but they buy for one reason — they expect upside. That makes the low-area buy signal worth tracking. 6

PANW: the CEO appears to have nailed the lows. That kind of insider timing is a useful tell when price action is trying to carve out a base. 7

Doing the actual work remains underrated. In markets, edge usually comes from reps, prep, and process — not from headline-chasing. 8
