Top 20 Stocks Are Now Over 50% of the S&P 500. Should You Be Worried? + $CRWD $NU $CIFR $ASTS (E153)

9 Oct 2026 · 58 min · Episode 153

Badger calls in from Crete after a week in which he trimmed $CRWD to 3% of his retirement portfolio and nearly sold $NU on a Monzo rumor. Monkey read a bear essay on AI spending and started talking himself out of $CIFR. The top 20 stocks were 38% of the S&P 500 at the dot-com peak and are over 50% now; Badger's argument, after ten bull and bear cycles, is that it may not matter which one we're in. With three weeks left in year three of King of the Jungle, the co-hosts are within 2% of each other (and kicking the market's butt).
