Why TEM stock is down today
Tempus AI Inc A stock fell 5.35% to $60.62 in early trading on Monday. The decline followed a recent round of selling by top insiders and a shift in position by a major investor. The stock opened with a small gap lower and continued to drift down through the session.
What Happened
Ark Invest, the investment firm led by Cathie Wood, reduced its position in Tempus AI as part of its latest portfolio adjustments. The firm cut its stake in Tempus AI along with AMD and Twist, while increasing holdings in AI infrastructure and biotech stocks. This move signals a reallocation of capital away from Tempus AI at a time when the stock had been rising in recent sessions. Additionally, the CEO of Tempus AI, Eric Lefkofsky, executed two separate sales of shares on August 25, adding to the bearish sentiment. Another top executive, Thomas Schoenherr, also sold shares earlier in August.
What The Data Shows
The stock has been volatile over the past 52 weeks, trading between $40.77 and $104.32. Despite a recent 4.6% rise over the last eight sessions, the stock has struggled to maintain momentum. The intraday session showed a sharp decline from the open, with the stock falling from $63.53 to a low of $60.58. Volume was light at 0.9 million shares, which is only one-tenth of the 3-month average. Over the past 90 days, insiders have sold a total of $58 million in shares, with no insider purchases reported. The stock also printed a fresh 52-week low on August 31.
