Key Takeaways
A 17-year stretch of resilient equity markets may be conditioning investors to dangerously underestimate risk, blurring the line between disciplined investing and outright gambling. Even as geopolitical risks rise and inflation remains elevated, U.S. stocks have pushed to all-time highs, feeding a speculative fever that makes it easier than ever for investors to step into gambling territory without realizing it.
"The biggest danger isn’t that the markets can go crazy, but that they’ll make you go crazy, too," Jason Zweig, columnist for The Wall Street Journal, wrote in an April 2026 analysis. He points to the flurry of filings for highly leveraged ETFs and 24-hour prediction markets on bitcoin's price as evidence of a "gambling fever" setting in.
This perception is skewed by a market that has been, in fact, less volatile than usual. The S&P 500 has had fewer 1% intraday swings this year than in 2023, 2025, or 2022. The last brutal bear market, a 55.3% loss in the S&P 500 from 2007 to 2009, is a distant memory. Since then, every stock market decline has been a short-lived event, reinforcing a buy-the-dip mentality.
What's at stake is a generation of investors whose attitude toward risk has been shaped almost exclusively by markets that bounce back quickly. This experience makes them more receptive to taking big risks and expecting high returns, a finding supported by academic research. The danger is that when a true, prolonged downturn arrives, these investors will be unprepared for the psychological and financial shock.
Your attitude toward risk is not stable; it is heavily influenced by what you’ve lived through. Research by Nobel laureate William Sharpe shows that in boom times, investors expect higher returns at lower risk. This is compounded by what UC Berkeley economist Ulrike Malmendier calls experiential learning; investors who have only known rising markets expect their portfolios to deliver higher returns.
This phenomenon works in reverse as well. A survey of Barclays clients during the 2008-09 financial crisis found their allocation to stocks fell from 56 percent to 46.5 percent as the market crashed. Yet, paradoxically, the same investors clung to their self-image as risk-takers. We are all prisoners of our recent past, and with markets marching upward, it’s critical to recognize how this can skew decisions.
Before making a trade, Zweig suggests a simple checklist:
A pause to answer these questions can prevent an investor from falling into a spiral of impulsive, gambling-like trading.
