SEI stock rose 8.40% to $69.54 on Tuesday, driven by a combination of a significant insider purchase, a recent acquisition, and upward revisions to earnings guidance. The stock’s sharp intraday move followed a strong opening and continued momentum throughout the session.
What Happened
The stock opened with a 1.4% gap up from the prior close and climbed steadily throughout the day, reaching a high of $70.33 at 11:30 AM ET. The rally was fueled by a major insider transaction: director Teague Aj purchased nearly 8,000 shares for $501,000, increasing their stake to $8.4 million. This purchase occurred just one day before the company announced a $101 million acquisition of Omega Foundation Services, a move expected to bolster SEI’s infrastructure capabilities. Additionally, the firm raised its Q3 and Q4 adjusted EBITDA guidance by 23% and 48% respectively, with initial Q1 2027 EBITDA guidance also raised significantly. These developments, along with a recent price target increase from Piper Sandler to $82, contributed to the stock’s upward trajectory.
What The Data Shows
The stock has surged 146% over the past year and is currently trading near its 52-week high of $86.19. Over the last eight sessions, it has gained 40.2%, rising from $49.86 to $69.90. The recent session saw volume of 0.9 million shares, or 0.3 times the 3-month average. The stock has printed 18 fresh 52-week highs on Tuesday, indicating strong retail and institutional interest. With a market cap of $4.5 billion, a P/E ratio of 73.8, and trailing 12-month revenue growth of 70.5%, the company is trading at a premium to earnings but is showing strong top-line expansion.
What To Watch
The company has not scheduled earnings in the near term, but coverage breadth remains a key factor to monitor. Analysts from Needham and Piper Sandler have maintained positive outlooks, and any further guidance updates or strategic moves could influence the stock’s direction.
