The S&P 500 is the preferred inventory market index across the globe. Representing the five hundred largest corporations on the planet’s largest economic system, tracker funds following the main US benchmark are staple investments in lots of British buyers’ portfolios.
In eight out of the final 10 years, the S&P 500 produced a optimistic return. Final yr was one other success story, regardless of President Trump’s tariff measures and international conflicts. However are US shares poised for a crash in 2026? Right here’s my take.
Warning indicators
Yearly, scores of analysts and commentators prophesise about an imminent inventory market crash. Equally, many counter the doomsayers with bullish forecasts of superb beneficial properties. The reality is, no person is aware of what is going to occur for positive.
Nonetheless, we will examine the place we’re at the moment with earlier intervals in historical past and draw inferences accordingly. Worryingly, there are some crimson flags for S&P 500 shares as we enter the brand new yr.
One is the Shiller price-to-earnings (P/E) ratio. This valuation metric divides the present S&P 500 value by the typical of the final 10 years of inflation-adjusted earnings.
At the moment, it’s at 40.74. To place that quantity in context, that’s the second-highest stage in historical past, surpassed solely by the dot-com bubble. Many concern that a man-made intelligence (AI) bubble is inflating in at the moment’s inventory market. When bubbles pop, the following crash could be devastating.
Capital expenditure on AI by S&P 500 corporations totalled round $400bn in 2025. This yr’s estimates are over $500bn. If sentiment shifts, 2026 may show to be very painful for buyers in US shares.
Causes to be optimistic
Drawing parallels with the late 90s is tempting, however there are essential variations between the S&P 500 then and at the moment. Again within the dot-com period, many tech shares lacked earnings and sturdy money flows. The speedy share value will increase had been typically pushed by speculative frenzy.
Arguably, at the moment’s mega-cap tech companies are in significantly better form. They’re extremely worthwhile companies with sturdy fundamentals throughout a variety of metrics.
AI potential may be driving share costs larger, however concrete earnings can justify the joy. These anticipating an S&P 500 crash this yr could properly discover their fears are unfounded.
An undervalued Magnificent 7 inventory
A full-blown crash is a chance, however I err on the facet of optimism. In any case, the good Benjamin Graham stated: “To be an investor, you have to be a believer in a greater tomorrow“.
However, I’m aware of overvaluation, too. That’s why I just lately invested in Meta Platforms (NASDAQ:META), the proprietor of Fb, Instagram, and WhatsApp.
With a ahead P/E a number of round 22.2, Meta’s the most affordable of the Magnificent 7 membership on this metric. I feel the inventory may shine this yr, supplied the entire market doesn’t crash.
Third-quarter earnings had been spectacular, with income rising 26% to $51bn and every day customers rising by 8% to three.54bn. Precision-targeted promoting continues to be a money machine for the corporate and the width of its moat within the social media world can’t be overstated.
Regulation is a rising danger for the corporate. Australia’s social media ban for under-16s may encourage different nations to comply with swimsuit, which may harm the Meta share value.
Nonetheless, I feel Mark Zuckerberg is likely one of the most gifted and aggressive S&P 500 CEOs. At at the moment’s value, Meta might be a long-term outperformer.
