Over $249 million in single-leg call premium was purchased across the seven largest cap stocks (Apple, Microsoft, Nvidia, Tesla, Alphabet, Meta, Amazon) in a single session. Nvidia, Tesla, and Apple accounted for 46% of this flow, suggesting concentrated bullish bets on the three most volatile names in the group.
