Stock Selloff Ends 50-Day Calm Streak, Sends Investors Into Gold and Bonds

The S&P 500 had gone more than 50 trading days without a single-day drop of 1% or more, a stretch of calm by historical standards. That streak ended in the session on October 15, 2026, and the reaction elsewhere in markets showed investors moving toward safety. Gold held near $4,160 an ounce as the stock selloff drove a rally in bonds, pushing Treasury yields lower. The dollar also weakened, giving the euro what one wire report called a 'much-needed reprieve' as worries about AI spending shook currency markets too. Nasdaq futures slipped heading into the next session, with traders citing both the scale of AI-related capital spending and renewed concern about the Federal Reserve's rate path as the twin pressures weighing on tech shares. The pattern is a classic one: when a long calm period breaks, money often rotates out of the assets that led the rally and into traditional havens like gold and Treasurys. What remains unresolved is whether this is a single volatile session or the start of a longer repricing of AI-related stocks. Since 1950, 54 similar calm streaks have preceded a full year of further market activity, but outcomes in those cases varied widely, so this single session does not settle the question either way.
