S&P 500 Hits Record $7,165 on AI Surge Despite 154-Year Valuation Peak

The S&P 500 soared to a record $7,165.08, up 0.80% (+$56.68), propelled by AI giants like Nvidia (+4.3%) and Alphabet, plus an Iran ceasefire easing tensions, targeting over 3% YTD gains. This caps an ~8% April rally and ~300% decade-long returns, but follows a February Shiller CAPE peak at 40.1—the highest in 154 years since dot-com. Invesco research warns high CAPE levels historically precede weak or negative 10-year returns, balancing bullish tech momentum with long-term caution.
