A new exchange-traded fund seeks to expose investors to gains from three of the most popular stock indexes while taking on only one major index's losses.

The Innovator Triple Stacker ETF, managed by Innovator Capital Management, will offer investors capped upside exposure to funds following the S&P 500, the Nasdaq 100, and the Russell 2000 and aim to limit losses to just the S&P 500, Innovator said on Wednesday. The fund will trade under the ticker TSOC.

The announcement was part of Innovator's reveal of three "stacker" ETFs, the latest complex investing tool to hit the market.

The second offering is Innovator's Double Stacker ETF, which cuts out the Russell 2000 and is otherwise the same as the triple-stacker fund. The ETF will trade under the ticker DSOC.

Third is the firm's Double Stacker 9 Buffer ETF. It also tracks the S&P 500 and the Nasdaq 100 but includes the buffer against the first 9% of a year's losses. The fund will trade under the ticker DBOC.

The firm said its new vehicles are set to list on October 1.

Stocks fell in early September on a broad tech-sector slump — investors ditched lofty valuations for value stocks as tech giants sat at record highs. With stocks struggling to retake record highs and with low rates stifling yields, some firms have turned to alternative investments for fresh gains.

All three funds will charge a 0.79% management fee and rebalance annually to reset investors' upside caps, Innovator said.
