SEI Investments Company (SEIC) Stock Price & How to Invest

SEI Investments Company (Nasdaq: SEIC) provides technology, outsourced operations, and asset-management services to the wealth and investment industry through four segments: Investment Managers, Private Banks, Investment Advisors, and Institutional Investors. It runs platforms and back-office administration for asset managers, banks, and financial advisors, and it also manages and distributes its own investment products. As of March 2026 the company managed, advised, or administered roughly $1.9 trillion in assets, split between about $554 billion of assets under management and roughly $1.29 trillion of assets under administration. Much of the revenue is recurring, tied to asset levels and long-term processing contracts, which gives the business a sticky, fee-based profile.

The investment picture is one of a mature, profitable operator rather than a high-growth disruptor. In Q1 2026 revenue rose about 13% year over year to roughly $622 million, operating margin expanded to around 30%, and diluted EPS grew to about $1.40 (adjusted near $1.44). The company generates strong free cash flow, buys back stock consistently, and has raised its dividend for more than a decade. The trade-off is that growth is moderate and cyclically sensitive to markets and client flows, so the stock tends to be valued as a quality compounder at a mid-teens earnings multiple.

SEI's fee revenue is tied to asset values, so a sustained market downturn or client outflows would pressure results. Competition is intense and consolidating, with SS&C (which acquired Envestnet), FIS, FNZ, and the large custody banks all vying for the same outsourcing and platform mandates. Large platform-conversion projects can face delays or cost overruns, and the Institutional Investors segment faces secular pressure as defined-benefit pension assets shrink. The business is also exposed to regulatory change, cybersecurity and operational risk given the scale of assets it administers. Finally, as a mature operator, growth is moderate, so multiple expansion is limited if execution slips.

SEIC traded around the mid-$90s in July 2026 with a market cap near $11.5 billion and a mid-teens P/E, a valuation consistent with a steady, cash-generative compounder rather than a high-growth name. Q1 2026 revenue grew about 13% year over year to roughly $622 million with operating margin near 30%. The company pays a semi-annual dividend (about $0.52 per share declared in May 2026) and has raised it for more than a decade.

There are three common ways to get SEIC exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so SEIC sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where SEIC fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

SEIC is a durable, cash-generative fintech-and-asset-management operator whose appeal rests on recurring fee revenue, long-run margins, and a multi-decade dividend record rather than explosive growth.

Whether SEIC is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is SEIC a buy?, and where the stock could go from here in the SEIC stock forecast.
