Meh...i’m not sure that tax loss comes into play here...as far as i know, you can only write off $3,000 of short term or long term losses per year....so if someone does sell all their stock at once for a loss, the cap for deductions is still 3k a year and the rest of the loss is carried to the next year with same limit. https://finance.zacks.com/there-limits-stock-...-3133.html
