Estimates only. Not financial advice.
Lock-in-now is deterministic (0%). Plans that wait depend on future prices; risk is near-zero when inventory comfortably exceeds the goal. Volatility: each stack's option-implied vol if a ticker is set, otherwise 30%. Lognormal model; real markets have fatter tails.

Spun out of Corning in 1997, the company operates the other national clinical laboratory network, collecting specimens through thousands of patient service centers and processing them in regional facilities. Payer contracts determine price and physician relationships determine volume, so commercial negotiations matter as much as operations. Consumer-initiated testing and employer wellness programs have added channels that bypass the physician order. Automation and specimen routing are where cost advantage is actually won. Headquarters are in Secaucus, New Jersey.

If you hold vested Quest Diagnostics (DGX) shares and need a set amount of cash by a date (a house down payment, tuition, a sabbatical, a business buy-in), the question is which lots to sell and in which tax years to keep the most after tax. This calculator builds the minimum-tax sell schedule across your lots, accounting for federal long-term capital gains, the net investment income tax, and your state.
Example: a 5,000-share DGX position at $236.25 is worth $1,181,250. Say you need $150,000 of it for a house down payment by next spring. Selling enough shares all in one tax year can push the gain into the higher long-term capital-gains bracket and trigger the 3.8% net investment income tax; spreading the sale across two tax years often nets more. The calculator above finds the minimum-tax sell schedule across your specific lots, basis, goal, and date.

Quest Diagnostics equity questions
- How much DGX stock do I sell to fund a goal without overpaying tax?
- It depends on your cost basis, your target amount and date, and how the sale spreads across tax years. Selling vested DGX shares triggers long-term capital-gains tax, plus the 3.8% net investment income tax and state tax above certain income, and bunching a large sale into one year can push the gain into a higher bracket. The calculator above builds the minimum-tax sell schedule across your lots to net your target amount by your date.
- Does Quest Diagnostics grant ISOs, NSOs, or RSUs?
- Equity compensation at Quest Diagnostics typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
