Why TENB stock is down today

Tenable Holdings Inc (TENB) fell 6.64% to $35.25 in morning trading on the back of a downgrade from Truist. The firm adjusted its rating to Hold from a prior position, citing a more balanced risk-reward profile and limited upside potential. The stock opened with a 3% gap down and has continued to trend lower throughout the session.

What Happened

Truist downgraded TENB to Hold, raising the price target to $40. The move reflects concerns over valuation despite the company's 10.7% year-to-date revenue growth. The stock is currently trading below its 52-week high of $43.67 and is now valued at a market cap of $4.4 billion. Tenable remains unprofitable with an earnings per share of -0.10 for the trailing twelve months and a net margin of -1.2%. The downgrade has triggered a sharp intraday selloff, with the stock hitting a low of $34.67 shortly after the market opened.

What The Data Shows

The session has seen a volume of 0.6 million shares, which is 0.2 times the 3-month daily average. The stock opened at $36.61 and has since fallen to $35.25, with a high of $37.23 and a low of $34.67. The 30-day average sentiment score has declined from 62 to 40 in the last seven days, reflecting a deteriorating outlook among investors. The stock's beta of 0.93 indicates it is slightly less volatile than the broader market.
