What State Street does
State Street is one of the oldest US financial institutions, founded in 1792 and based in Boston. Its core business is servicing assets for institutional investors: safekeeping securities, fund accounting and administration, recordkeeping, client reporting, collateral and cash management, and outsourced investor-services operations. Around this it offers trading services (foreign exchange, brokerage), securities finance including prime services, and data, risk and compliance analytics. The company also sells technology through its State Street Alpha platform, which links portfolio management, trading, compliance and data tools across the investment process, and runs an investment management arm offering equity, fixed income, cash, multi-asset and alternative strategies through ETFs, indexed funds and mandates. Clients include mutual funds, retirement plans, insurers, wealth and investment managers, foundations and endowments.

What is State Street worth?
On an owner-earnings DCF, State Street's most-likely value is about $755 versus a recent price near $175 (331% below fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$398) with a margin of safety — so the honest verdict here is “Deeply discounted.” Fair value earns its keep only at the extremes, not in the wide middle.
On the financials alone, $175 is below even the no-growth floor ($398); the market's discount — expectations and sentiment beyond the numbers — is pricing in ≈ -11.5%/yr. A bargain only if that pessimism is overdone.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
