Meta still ranks at the top on profitability (A), but its 1-year return of -18.0% is the only clear decliner among the megacaps in this batch. Core advertising cash generation remains solid, but heavy AI infrastructure capex has raised near-term margin concerns and driven the pullback.

Worth noting: after the drop, valuation (C, ~23x P/E) now sits in a less demanding range than most other megacaps here. Until it's clearer whether AI investment is translating into better ad efficiency or new revenue streams, the stock warrants a volatility-aware approach.
