Trump's Iran Strikes Are Fueling Monday Stock Rallies This Quarter

A striking trend has taken shape in U.S. equity markets during the second quarter: stocks have been rising more sharply on Mondays than they have in recent years, and analysts are pointing to a clear culprit — weekend developments tied to Trump administration strikes on Iran. The pattern is drawing enough attention that traders are already giving it a nickname: the "Axios put," a nod to how breaking weekend news drives Monday morning moves.

The data shows that average Monday gains in Q2 have outpaced comparable periods in recent years, suggesting that geopolitical headlines delivered over the weekend — particularly those signaling military action or diplomatic escalation with Iran — are functioning as a market catalyst rather than a drag.
