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. The stock opened at $21.51 and reached a high of $24.59 before settling near $22.85. With 4.7 million shares traded so far, the volume is 0.7 times the 3-month average. The stock has been the subject of four news stories from two sources in the past 36 hours.

What Happened

The Fly reported that Fastly's CEO, Charles Lacey Compton, sold 2,436 shares of stock. This follows recent insider transactions, including sales by the CTO and the CEO on three separate dates in late August and early September. The Fly also noted that call volume has exceeded normal levels and is directionally bullish. The stock opened lower but reversed sharply higher, reaching a session high just after 10:00 AM ET. 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.

What The Data Shows

Fastly has a market cap of $3.3 billion and remains unprofitable with a trailing twelve-month EPS of -0.53. Revenue is growing at 20.4% TTM, but the company's net margin remains negative at -11.8%. The stock is currently trading within its 52-week range of $7.29 to $34.82. Unusual options activity included two notable prints, with $484,000 in call premiums compared to $0 in put premiums.
