The U.S. and Iran have tentatively agreed to extend their ceasefire by 60 days, which could signal the three-month conflict is winding down. Stocks rallied on the news, and separately, a rare contrarian buy signal just flashed as market-timers panicked — historically a sign that stocks tend to climb higher.

## Idea

A tentative U.S.-Iran truce deal is the biggest geopolitical de-escalation signal in months, and it's already lifting stocks as investors price in lower war risk. At the same time, MarketWatch reports that market-timers bailed on stocks at a near-unprecedented pace — historically, when everyone suddenly turns bearish and a positive catalyst arrives, stocks tend to grind higher as the skeptics are forced back in. Citadel Securities' Scott Rubner also flagged that the 'pain trade' is for stocks to keep rising. Together, these create a classic setup: a big macro relief catalyst arriving while skeptics are underinvested, which often fuels a multi-week rally.
