The Piggy Bank You Fill by "Losing Money." Yes, Really.

Most investors think about tax loss harvesting the wrong way. They treat it as an annual tax move - something you do in December when the market is down to offset a gain somewhere else. That framing undersells it by a factor of ten.

Tax loss harvesting, done systematically, is not a year-end cleanup. It is a compounding asset. Every loss you harvest goes into the bank. And that bank pays dividends every time you have a taxable event for the rest of your investing life.

How the Bank Works

When you sell a position at a loss, you realize a capital loss. That loss can offset capital gains dollar for dollar, reducing your tax bill in the year it is used. The part most people miss is what happens to the rest: if you have more losses than gains in a given year, the excess carries forward indefinitely. There is no expiration date on a harvested loss.

So every loss you harvest this year - even if you have no gains to offset right now - is sitting in a carryforward account, growing in value, waiting for the moment you need it. A real estate sale. A business exit. A concentrated stock position you finally decide to diversify. RSUs vesting at a high price. The loss bank is ready for all of it.

The Ossification Problem

Traditional tax loss harvesting has a flaw: it stops working. In the early years of a portfolio, when positions are new and cost basis is recent, losses are easy to find. But after three to five years of market appreciation, most positions are sitting on gains. There are no losses left to harvest. The portfolio has ossified.

The solution is a long-short strategy - a separately managed account that systematically holds both long and short positions, generating losses continuously regardless of market direction. The longs hold your market exposure while the shorts keep generating losses, so the machine keeps running even when the market goes up, filling the piggy bank year after year.

At STQ, we implement long-short tax loss harvesting strategies that build the bank systematically - not just in down years, but in every year. The earlier you start, the larger the bank, and the more powerful the tool becomes when you actually need it.
