I'm Not Worried About a Stock Market Crash, and It's Because I'm Making This 1 Investing Move

The S&P 500 has soared for the past three years and continues to roar higher this year -- it's heading for a 100% gain over this entire period. Artificial intelligence (AI) stocks, as well as other growth players, led much of this bull market's momentum, and the long-term AI story looks exciting. AI has the potential to improve the way many things are done, in our lives and in the corporate world, and all of this may significantly boost earnings.

This is fantastic, yet some investors have started to worry about a potential stock market crash. That's amid general economic and geopolitical uncertainty and concerns about the massive tech investment in AI infrastructure. The questions certain investors have are whether the economy will support growth stocks in the coming quarters and whether AI revenue will surpass companies' investments in the technology.

Though a market crash is bound to happen at a certain point, I'm not worried about it. That's because I'm making this one investing move.

Will a market crash happen?

So, first you might wonder why I'm so sure that a market crash will happen. This is because crashes are part of the general investing cycle, and they do occur from time to time. Throughout history, there have been many, from the crash of 1929 to the coronavirus crash in 2020. All of this suggests that such an event will happen again.

Why are some investors convinced that the market is on the brink of such an event? For a few reasons. First, the stock market never climbs steadily forever, so after more than three years of gains, it's reasonable to consider when the next big decline might come. At the same time, these years of positive performance have resulted in a tremendous increase in valuations, as seen in the S&P 500 Shiller CAPE ratio. The measure is extremely reliable, as it considers stock price and earnings over a 10-year period to account for the changing economic environment.

As you can see in the chart above, this ratio has reached a high, showing that stocks are very expensive right now. And such peaks have always resulted in a decline in the S&P 500. Meanwhile, any earnings disappointment or slowdown in AI demand could prompt some investors to sell stocks -- and the index could drop.

Of course, a potential decline could be small, or it could be a crash -- and the length of the downturn may vary too.

The power of quality stocks

Now here's why I'm not worried: I'm feeling calm about any potential crash because I'm holding onto quality stocks for the long term. For example, I've owned e-commerce and cloud giant Amazon and biotech innovator Vertex Pharmaceuticals for a number of years, and I don't plan on selling any time soon. So, if the market crashes and these and other players tumble, that's OK. I know they have the financial strength and competitive advantages to help them recover and grow after the storm has passed.

Data supports this. If you invested in U.S. stocks at the peak right before the global financial crisis in 2007, you would have seen a 40% decline after a year -- but you would have seen a 109% increase after 10 years, according to iShares by BlackRock.

A look at the S&P 500's performance shows us that it has always delivered a win over the long run.

And the same is true for companies that have well-established market positions, a track record of earnings growth, and solid long-term prospects.

So, right now, if you want to push aside worries about a potential market crash, you can do two things. First, as I'm doing right now, hold onto stocks that you believe in. Even if they decline during difficult times, they are likely to recover if you hold onto them for several years. Second, use any declines to get in on quality stocks at a good price. These two techniques will help you beat any market crash, and that means, like me, you don't have to worry about the next one.
