Stock Gains Without the Stress? The "Safety Net" ETF That Protects You From the First 15% of Market Losses

Retail investors have a few ways to reduce risk in a stock portfolio. If you want to hedge an equity position, you could add bonds, buy put options, or simply hold part of your portfolio in cash. Each of these approaches can work, but they all come with trade-offs.

Bonds are often viewed as a stabilizer, yet they can move in the same direction as stocks when interest rates rise. That happened in 2022, when both stocks and bonds fell together.

Put options provide direct downside protection, but they come with a cost. The premium you pay creates a steady drag on returns, and options lose value over time through theta decay.

Holding cash has its own drawback. Even when parked in interest-paying Treasury bills, the return may struggle to keep pace with inflation over long periods.

There is, however, a fourth option that many retail investors overlook: buffer ETFs. These are more sophisticated ETFs that resemble the structured products often used by institutions.

A useful way to think about them is like investing in a stock index with training wheels. The category has grown quickly, and there are now many variations of buffer ETFs on the market. Some can be quite complex, so it’s easy for beginner investors to get overwhelmed.

Today we will look at one of the more straightforward examples: the Innovator U.S. Equity Power Buffer ETF April series (CBOE:PAPR). Here is how the strategy works and some of the trade-offs investors should understand before using it.

Unlike a traditional ETF, PAPR does not actually hold stocks. Instead, it holds a portfolio of index options designed to produce a specific risk and return profile over a defined period.

PAPR operates over a one year outcome period that begins every April. During that time, the ETF attempts to accomplish two things.

1. First, it seeks to protect investors against the first 15% of losses in the S&P 500.
2. Second, it aims to track the price return of the S&P 500 up to a predetermined cap.

The downside buffer is the most distinctive feature. If the S&P 500 declines during the outcome period, the ETF absorbs a portion of those losses. For the April series, that buffer is designed to cover the first 15% of downside during the one year window.

For example, if the S&P 500 falls by 10% over the period, the buffer absorbs the entire decline and your principal remains intact. If the index falls more than 15%, then losses beyond that threshold begin to affect the fund on a one for one basis.

This protection is created using a put spread. The ETF buys a put option to provide downside protection, then sells another put further out of the money. Selling the second put helps offset the cost of the first one, but it also means that once losses exceed the buffer level, the ETF resumes participating in further declines.

The strategy still needs another source of financing, which leads to the second component. PAPR sells an index call option The premium received from that call helps pay for the downside protection. The trade-off is that the short call option limits how much upside investors can capture. This creates a return cap for the outcome period.

Looking at the current cycle provides a good example. As of March 6, the ETF has about 25 days remaining in its current outcome period. At the start of this cycle last April, the cap was set at 12.39% before fees, which works out to roughly 11.6% after expenses. The downside buffer was set at 15% before fees, or about 14.21% net.

In other words, over the one year period investors could capture price gains in the S&P 500 up to about 11.6%, while being protected from the first 14.21% of losses after fees.

Buffer ETFs are often used by financial advisors, but the mechanics can easily trip up retail investors. There are several details that investors need to understand before using a fund like PAPR.

The first is the outcome period. The caps and buffers we discussed earlier only apply over a specific one year window. For PAPR, that window begins each April and ends the following April. At the end of the period, the structure resets and a new cap and buffer are established based on market conditions at that time.

To fully capture the intended protection and upside cap, an investor needs to buy the ETF at the beginning of the outcome period and hold it until the end. Buying the ETF midway through the cycle can change the payoff significantly.

For example, if the market has already risen during the outcome period, some of the cap may already be used up. That leaves less remaining upside for new investors. On the other hand, if the market has already fallen, part of the downside buffer may already be consumed, which reduces the protection you expected.

Because of this timing issue, providers such as Innovator offer multiple versions of their buffer ETFs with different starting months. Each “vintage” corresponds to a different outcome period. In this case, PAPR refers to the April series.

The second point is dividends. PAPR is designed to track the price return of the S&P 500, not the total return. That distinction matters. A meaningful portion of long term stock market returns comes from reinvested dividends.

Since buffer ETFs typically capture only price movements, they do not participate in those dividends. This means the long term return potential is already lower compared with simply holding a broad market index ETF.

The third consideration is cost. Low cost S&P 500 ETFs can charge expense ratios as low as 0.02%. On a $10,000 investment, that is roughly $2 per year in fees. PAPR, by comparison, carries an expense ratio of 0.79%, or about $79 per year for the same investment size.

This naturally raises the question of whether investors could create a similar outcome using a combination of a traditional S&P 500 ETF and cash. In many cases, the answer is yes. A mix of stocks and cash, periodically rebalanced, can reduce volatility and limit downside exposure.

However, doing this yourself requires more monitoring, adjustments, and discipline. It also lacks the defined payoff structure that the buffer ETF provides. For risk-averse investors who value that certainty and are willing to pay 79 basis points for it, PAPR may serve a role in a portfolio.

Just remember that the protection comes with trade-offs, including lower upside potential, no dividend participation, and the need to pay attention to the outcome period when buying the ETF. Personally, I still believe a simpler combination of stocks and cash can achieve similar results at lower fees without the added complexity.
