Palo Alto Networks' shares experienced significant volatility following the release of its Q3 earnings report. Despite beating expectations on both top and bottom lines, the company's stock fell 8% in late trading due to a disappointing sales forecast and billings outlook. The cybersecurity firm projected Q4 billings between $3.43 billion and $3.48 billion, and revenue between $2.15 billion and $2.17 billion. This marks the third consecutive quarter where Palo Alto's stock has dropped more than 5% post-earnings. Analysts noted that while the company met its guidance, the market's high expectations contributed to the negative reaction. Options were pricing about a 9% expected move, with implied volatility (IV) for options expiring this week at 120. The company's RPO held around 23%, and DRs ticked down to 26%. The stock fell 10% after hours.
