AI Security Stocks Enter Oversold Zone, $800 Million Market Cap Vanishes in a Day
By ATTN Desk · Editorial oversight: Sean Han
Rubrik Inc. (NASDAQ: RBRK), a U.S. cloud data security firm, plunged 8.85% on the New York Stock Exchange on the 27th, closing at $62.26 with a trading volume of 6.48 million shares. Its market capitalization declined by roughly $780 million—almost KRW 1 trillion—in a single day, leaving its current valuation at about $9.5 billion (around KRW 12 trillion).
According to a Nasdaq analysis, Rubrik’s share price fell as low as $62.60 intraday, pushing its Relative Strength Index (RSI) to 29.2 and entering technically “oversold” territory. This adjustment comes despite the company’s Q3 results announced in December 2025, which significantly beat revenue and earnings estimates, and an upwardly revised fiscal 2026 guidance. (nasdaq.com)
Rubrik offers cloud data security and recovery solutions, including ransomware protection and data backup. Riding on expanding demand for AI-driven security and data protection, the stock jumped about 90% above its IPO price from its April 2024 listing through early 2025, marking it as a standout growth name.
