State Street equity questions
- How much does it cost to hedge STT stock?
- The cost of a protective put depends on how far below the current price you set the floor, how long the protection lasts, and STT's option-implied volatility. A zero-cost collar lowers that cost by selling away some upside. The calculator above prices both structures off the current STT option chain and shows the annual cost, maximum loss, and tax treatment.
- Does State Street grant ISOs, NSOs, or RSUs?
- Equity compensation at State Street typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do State Street RSUs use double-trigger vesting?
- No. State Street restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
