Options Buying Amplifies the Stock Market's Four-Day Rally

A swift four-session surge in equity markets has triggered a familiar dynamic on Wall Street: traders scrambling to catch up are turning to options markets, where leveraged bullish bets can generate outsized gains quickly.

Analysts watching dealer positioning and open interest will be the first to detect when the tide is turning. For now, momentum and derivatives flows remain aligned, giving the rally additional runway even as valuation concerns linger in the background.
