Dover equity questions
- How much DOV stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your DOV position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Dover grant ISOs, NSOs, or RSUs?
- Equity compensation at Dover typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Dover RSUs use double-trigger vesting?
- No. Dover 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.
