Market looks strong but is it basically just NVDA and friends carrying everything?

Serious question. Index keeps grinding up, AI narrative everywhere, but when you actually look under the surface, a few mega caps doing all the heavy lifting, everything else either chops or fades. This doesn’t feel like past cycles where leadership rotated and you had multiple ways to win. Right now it’s more like, AI runs = capital piles in = everything else lags = repeat Mid caps? inconsistent. Small caps? mostly noise unless you catch a clean move early. So yeah, market looks strong but it’s narrow. I was messing around with GetAgent earlier just to break down sector contribution and scenario outcomes, and it basically reinforced the same thing, if the top names stall, the whole “strength” story starts looking fragile pretty fast. Not calling a top or anything, just feels like we’re way more dependent on a few names than people want to admit. So what’s the play here, ride the leaders and ignore everything else or start looking for rotation that hasn’t shown up yet?
