I/O Fund: the 17-year bull market has room to run, but a ~20% correction comes first

Beth_Kindig · x · 2026-10-16

I/O Fund argues the current bull market, running since March 2009, is now 17 years old — an extreme outlier versus 150+ years of secular trends.

Key points: the AI bull market has considerably more room to run, but a notable correction will shake investors out before the next leg higher; the S&P 500 has seen five 20%+ declines since 2009, mostly quickly recovered. Understanding the secular trend matters more than stock picking, and the AI proxy $SMH appears to confirm the correction-first thesis.
