Why Rocket Lab Stock Dropped Today

Rocket Lab (RKLB) shares fell 12.2% on Nov. 5 amid a broader tech sell-off, despite no direct ties to AI. The decline was part of a wider market downturn, with the S&P 500 and Nasdaq dropping 4.4% and 5.6%, respectively. Investors are concerned about potential scrutiny of data center construction. Rocket Lab's high P/S ratio of 40 contributed to its classification as a speculative stock. The company is set to report Q3 earnings on Monday, which could impact investor sentiment.
