ProShares Nasdaq-100 Dynamic Buffer ETF (QB)

The ProShares Nasdaq-100 Dynamic Buffer ETF is an options-based fund from ProShares, the Bethesda, Maryland-based ETF sponsor known for leveraged, inverse and strategy products.

The fund holds exposure to the Nasdaq-100 Index and uses options to soften losses during market declines. Unlike traditional buffer funds tied to a fixed annual outcome period, its protection is described as dynamic, meaning the option hedges are adjusted on a rolling basis so the buffer applies continuously rather than resetting on a single date. The cost of the hedges limits some of the upside.

It trades on the Nasdaq under the ticker QB.
