FASTLY INC A (FSLY) rose 6.24% to $22.83 in intraday trading on Tuesday, driven by unusual call options activity and elevated trading volume.

What Happened

The Fly reported that Fastly's CEO, Charles Lacey Compton, sold 2,436 shares of stock.

No earnings report or corporate action was announced, but the stock's movement suggests a combination of speculative options activity and retail or institutional buying.
