IS $SPX RE-RUNNING 1999? BofA WARNS OF AI BUBBLE DEJA VU 🧠📉

Bank of America just flashed a chilling déjà vu signal — current index structure echoes the 1999 bubble top. S&P 500 concentration sits at historic extremes, active stock selection at record lows, and passive money keeps crowding into a few AI winners. That's the classic pre-bubble-unwind footprint. 📉

The $500B Nvidia-backed AI infrastructure push adds another layer. Bulls see a long-term funding pipeline for chips and data centers. Bears smell vendor financing — capex morphing into leverage, not genuine industrial investment. 🏗️

The real question: when AI revenue lags capex, does index volatility amplify? Are we watching a rotation or a top forming? Drop your read below. 👇
