The Wash-Safe rule and investment losses

Smart Year-End Tax Moves for Investors

Excerpt:

If you sell an investment at a loss, you don't get the loss if you also buy the same holding 30 days before or after the sale. What many don't know is that these rules apply only to losses, not to gains. In the above example, Susan was free to re-acquire the stock she sold right away at a higher cost basis, which will reduce her taxable gain in the future. As long as transaction costs are low, it often makes sense to "scrub" your gains if you have losses.

Comment: More on the "Wash-Safe" rule. I have one investment that I may sell and take the loss to offset gains.
