- Wrongo! The basis for the 100 shares you sold is $10.
- The basis for the shares you still hold is $1.
-
- Your mistake is in trying to adjust the basis for shares sold by the cost
- of all shares purchased, when what you must do is adjust the basis of
- ^^^^^^^^^
- shares sold by the cost of all shares sold.
- ^^^^
- Example: If you had sold 150 shares and used FIFO, then you would have
- total adjusted basis = 100*$10 + 50*$1 = $1050
- total shares = 150, avg basis = $7
- remaining shares held = 50, avg basis = $1
