@Mike9241 Posed this question below. Interested in your input too:
I was just curious if, for example, you bought 100,000 shares of a stock in a taxable account throughout the year and 500 shares of a stock in a retirement account:
1. Is the MOST that could be washed out from the retirement activity 500 shares -- and therefore 500 x cost basis of select shares of the 100,000 - even if say 60,000 of the taxable shares were traded within 31 days of the retirement account activity? Or would all the losses associated with the 60,000 be washed out since it took place within 31 days of the purchase of the 500 in the retirement account?
