Leveraged ETFs Explained: Daily Reset and Volatility Decay
A leveraged ETF aims to deliver a multiple of its index's daily return, not its long-run return, so losses compound fast in volatile markets. Here is how it works, using the 3x chip ETF's 38% fall on November 5, 2026.
On Thursday, November 5, 2026, chip stocks had their worst day since March 2020: the iShares Semiconductor ETF fell more than 12% as investors questioned the pace of the AI data-centre buildout. Funds designed to triple the daily move of a semiconductor index fell about three times as far. On Binance, the tokenised version of SOXL, the Direxion Daily Semiconductor Bull 3X fund, went from $66.74 at the US close on Wednesday to $41.07 at the close on Thursday, a loss of about 38.5% in one session. A holder lost more than a third of the position in six and a half hours of trading.
A leveraged ETF uses swaps, futures or borrowed money to deliver a fixed multiple of its benchmark's return, typically 2x or 3x, and an inverse fund delivers the opposite, such as −1x or −3x. The key word in the prospectus is daily. The fund rebalances its exposure at every close so that the next day starts again at exactly 3x. It promises three times today's move, not three times the move over a week, a month or a year.
That daily reset is what creates volatility decay. Suppose an index starts at 100, falls 10% to 90 and then rises 11.1% back to 100. The index is flat. A 3x fund falls 30%, from 100 to 70, then rises 33.3%, from 70 to about 93.3. It has lost 6.7% while the index went nowhere. The more the index swings back and forth, the larger the gap, because each loss shrinks the base on which the next gain is earned. In a steady trend the effect can work in the holder's favour; in a choppy market it eats the position.
The same arithmetic makes big down days dangerous. A 3x fund cannot fall more than 100%, but an index drop of about 33% in one day would wipe it out, and a sequence of 10% to 12% drops, like November 5, removes a third of the capital each time. Recovering from a 38.5% loss needs a gain of about 63%. Because the funds rebalance near the close, they also have to sell into falling markets and buy into rising ones, which can add to moves at the end of volatile sessions.
These products are built for short holding periods by traders who watch them daily. Regulators have said so repeatedly: the SEC and FINRA have warned that leveraged and inverse ETFs held for longer than a day can return something very different from the stated multiple of the index, especially in volatile markets. Fees are also higher than for plain index funds, and the cost of the leverage itself rises with interest rates.
If you use one, decide the holding period before you buy, set a stop based on the fund's own volatility rather than the index's, and size the position as if it were three positions, because it is. Compare the fund's return with three times the index's return over your holding period to see how much decay you paid. And treat a day like November 5 as the normal risk of the product, not a rare accident. Trade2Spike's simulator lets you practise leveraged positions with stops and position sizing without real money at risk.
