An end-of-week feeding frenzy in options of the world’s biggest companies has emerged as two of the hottest trends on Wall Street collide.

Rampant demand for Big Tech exposure is combining with the boom in fast-expiring options to fuel an explosion in bullish bets in the first few minutes of Friday trading.
