For ETF investors bearing the brunt of a down market in 2022, tax-loss harvesting might offer a silver-lining opportunity to redeem some of this year's setbacks.
The strategy allows investors to sell securities at a loss in order to offset those losses against capital gains taxes on other securities.
Tierney, senior portfolio strategist at Schwab Asset Management Solutions, told Bob Pisani on CNBC's "ETF Edge" on Monday.
"You have this opportunity before the end of the year to sell that fund, realize the loss, [and] stay invested by buying an aggregate bond ETF," he said.
Tierney said he is also perceiving levels of increased interest in the strategy among ETF investors, pointing to telltale signs among advisors and clients at Schwab.
