SEI Investments Short Interest Climbs to Year High as Analysts Push Targets Up

SEIC is the least crowded name among its closest asset-management peers, yet it now carries more short interest than at any point in at least a year, a divergence that sits oddly against a wave of analyst upgrades landing in the same week as its Q3 results.

Among close peers, BLK ended the week up nearly 6% and LSEG gained close to 5%, while the median move across the group was roughly flat at +0.2%. SEIC added 1.6% to close at $107.15, a respectable outperformance but modest against the backdrop of its own analyst story. Short interest at 2.6% of free float is low in absolute terms, but that reading is the highest in over a year: from around 1.9 million shares in early September, the borrowed position has expanded to 3.24 million, a 47% rise over 30 days. The bulk of that move happened in a single step around October 9, when borrowed shares jumped by roughly 600,000 in a day. Borrow availability remains extremely loose at over 2,190%, meaning there are far more shares available to lend than are currently out on loan, so the building short position is a matter of conviction, not a squeeze setup. Cost to borrow at 0.49% is negligible.

The options picture is calmer than short interest alone would suggest. The put/call ratio has dropped to 1.20, well below its 20-day average of 3.71 and now sitting near the lower end of its year-long range. That average is skewed by a September spike above 8.75 that has since fully unwound. The current reading implies options traders are no longer paying up for downside protection. Taken together, the positioning picture is one of modest and methodical short-building in the stock market, alongside normalising hedging demand in the options market.

The Street has moved firmly in one direction. Piper Sandler lifted its target to $127 on October 19, keeping an Overweight rating. Wells Fargo initiated at Overweight with a $129 target on October 2. Morgan Stanley, Keefe Bruyette, and Raymond James all raised targets after the Q2 print in late July. The consensus mean now stands at $118.38, about 10% above the current price. The analyst recommendation differential ranks in the 89th percentile across the ORTEX universe, a strong positioning signal. EPS surprise history also ranks in the 78th percentile, and 90-day earnings momentum sits in the 76th percentile, reflecting consistent positive revisions. The debate is largely about margin durability: bulls point to a 32% core operating margin in Q2 2026, the highest since 2009, while bears question whether the improvement is broad enough across segments to sustain itself.

Insider activity over the past 90 days has run net negative, with the 90-day net position at roughly minus 226,000 shares and net value of about minus $23.9 million. The largest individual move was CEO Ryan Hicke exercising options and then selling 37,500 shares at $110.71 on September 3, generating proceeds of around $4.2 million. Founder Alfred West sold nearly 34,000 shares across two days in late September at prices just above $103. None of these sales were filed under a pre-arranged 10b5-1 plan, though at these volumes for a founder holding over 16 million shares, the context matters: West retains a 13.4% stake, the single largest on the register. BlackRock added over 590,000 shares in the most recent reported quarter, and FMR added nearly 443,000. Retail attention has spiked notably, with the Wikipedia views signal running a z-score of 3.8 against its own 90-day history, the kind of attention typically associated with an earnings event rather than an organic information cycle.

The Q3 results landed on October 21. The prior quarter's earnings day produced a modest one-day decline of 0.9%, followed by a five-day gain of 5.4%. The next scheduled event is now set for late January 2027. What changes the current picture most directly is whether the short position that built so sharply through October now unwinds, holds, or extends from here.
