Buffer ETFs Surge Amid Stock Market Volatility, Offering Downside Protection

The recent increase in stock market volatility has boosted the popularity of 'buffer' exchange-traded funds (ETFs), which provide downside protection while limiting potential gains. Assets in these funds have surged to over $41 billion in three years, driven by investor demand amid declining global stocks. The introduction of 'capital protected' variants further expands the market.

The recent surge in stock market volatility appears to be benefiting a particular segment of asset managers: those offering 'buffer' exchange-traded funds (ETFs). These ETFs allow investors to trade some upside potential in the stock market for a measure of downside protection. Over the past three years, investments in these funds have ballooned to over $41 billion from less than $10 billion. Amid the global market rout, these products have seen a spike in interest, with recent inflows serving as a testament to their growing appeal.

According to Morningstar data, average weekly net inflows into buffer ETFs have soared to $283 million since early July, up from $160 million during the first half of the year. In the week ending August 2, net inflows jumped to $360 million, following a weekly increase of $166 million. This comes as the S&P 500 index has lost around 5% this month, driven by economic concerns in the U.S. and the unwinding of a global carry trade, which has also impacted stocks in Japan and Europe.

'Our inflows last week were probably five or six times what we would see in a typical week,' said Graham Day, Chief Investment Officer at Innovator ETFs, which launched the first buffer ETF six years ago. Buffer ETFs generally use options to limit losses while also capping potential gains. Financial advisors are increasingly recommending these products to prevent clients from abandoning stock investments during volatile periods.

However, there are downsides to these ETFs. While they can buffer losses during market downturns, they also limit upside potential, particularly for long-term investors, cautioned Zachary Evens, a manager research analyst at Morningstar. 'The risk is that they're sold to investors who don’t need them due to their long-term investment horizon,' Evens said, adding that 'there are no free lunches in investing.'

The buffer ETF market has been rapidly expanding, with 76 new products introduced this year alone, offering between 9% and 100% downside protection on various indexes. This is an increase from the 66 products launched in 2023, bringing the total number of such funds to 297. Recently, a new category of 'capital protected' funds has also entered the market, promising 100% downside protection but with even less upside potential.

'This is where we see the opportunity,' said Matt Kaufman, head of ETFs at Calamos Investments, which introduced its first 'capital protected' funds earlier this year. 'This selloff is the first real-life test for these products, and so far, they are performing as expected.'
