Mag 7 Call Premium Surges $249M; NVDA, TSLA, AAPL Account for Nearly Half of All Single-Leg Call Buying

A massive $249M in bullish single-leg call option premium flooded into the Mag 7 tech complex in one session, with NVDA, TSLA, and AAPL absorbing nearly half of the total buying interest. This concentration of call buying in three names, all of which have benefited from AI narratives and the Trump-Xi summit optimism, signals that institutional traders are loading up for further upside and willing to pay for convexityThe curvature of a bond's price-yield relationship..

As the market rallies and these calls move into the money, dealers must buy more shares to remain hedged, creating a feedback loop that can accelerate moves higher. The risk of this dynamic is that it becomes self-reinforcing until a trigger event (economic data, geopolitical shock) forces a reversal and unwinding.
