Calculating Stock Basis

[frayne]

Does anyone know of a good site that helps to calculate stock basis for stocks bought over a period of time and that automatically averages in order to give a decent basis for calculating gains/losses ?

Thanks in advance.

I don't think you can use average basis for individual stocks. OK for Mutual funds only.

You have to either sell a specific lot, identifying it at the time of sale and using that lot basis, or the IRS assumes first-in,first-out (oldest lot sold first).

At Fidelity, you can select which lot you are selling, and they track the basis for each lot. I imagine many other brokers do the same.
