UnitedHealth (UNH) shares have plummeted to the downside in a strong downtrend thus far in 2025. Tom White looks at the healthcare company and discusses its weight on the Dow Jones Industrial Avg. ($DJI), potentially hampering the index from hitting all-time highs alongside the S&P 500 (SPX). Tom calls the steep pullback a "falling knife" and illustrates a duration-based example options trade. He composes a call vertical with a bullish tilt using October expiry strikes to give the trade time.
