This 17-year bull market is up 1,073% — I/O Fund expects a correction first
Beth_Kindig · x · 2026-10-15
I/O Fund compares the current bull market to secular bull markets since 1880: the historical average lasts 11.2 years with a +675% gain, while the current one — running since March 2009 — is 17.4 years old and up 1,073%, an extreme outlier. The report argues the secular trend matters more than stock picking, that five 20%+ S&P 500 drawdowns since 2009 reinforced buy-the-dip habits within a larger uptrend, and that AI stocks still have room to run — but only after a notable correction first shakes out many investors.
