Huh? If you're buying a diverse portfolio of equities then you're guaranteed to have some losers and some winners. You let the winners ride, sell the loses/bank the loss, and replace them with companies that have as similar risk profile to the one you sold as possible.

to reiterate what dragontamer is saying, if all of your investments are in IRAs (where there are no taxes, at all!), then TLH is meaningless.

only if you're maxing out your tax advantaged accounts, and still have additional funds to invest is TLH even relevant.
