How the value of a stock gift is calculated.

For publicly traded stock, IRS Publication 561 sets fair market value at the mean between the high and low selling prices on the valuation date.

  1. Take the day's high and low.

    Use the high and the low: the top and bottom prices the stock traded at on the date of the gift.

  2. Add them and divide by two.

    The result is the average value per share. Multiply by the number of shares for the value of the gift.

  3. No trading that day?

    Weekends and market holidays have no prices. IRS Publication 561 explains how to value a gift made on a day with no sales; ask your tax advisor.
