This Is the Most Expensive Stock Market in Over 25 Years. Should Investors Be Worried?

After posting 3 consecutive years of double-digit returns, lone the eighth clip it has happened since 1926, the banal market's astir important index, the S&P 500 (SNPINDEX: ^GSPC), has had a dilatory commencement to 2026. Through March 11, the scale is down astir 1% twelvemonth to date.

Even so, the S&P 500 is inactive astatine historically costly levels erstwhile looking astatine the Shiller price-to-earnings (P/E) ratio, besides known arsenic the CAPE ratio, successful notation to cyclically adjusted price-to-earnings.

The Shiller P/E ratio looks astatine the S&P 500's net implicit the past 10 years, adjusting them for ostentation to forestall one-off events from skewing the numbers. As of this writing, the Shiller P/E is astatine 39.2, nearing the highest level since mid-2000.

The past clip the S&P 500 was this costly was successful the heavy of the dot-com bubble. In November 1999, the Shiller P/E ratio peaked astatine astir 44.2. From that constituent until the trough of the dot-com bubble successful October 2022, the S&P 500 dropped by astir 40%.

In October 2021, the Shiller P/E ratio reached 38.5. From that constituent until the S&P 500 bottomed retired successful October 2022, the scale dropped by much than 20%.

So, historically, an S&P 500 this costly isn't rather a crushed to leap for joy. However, I can't accent capable that conscionable due to the fact that it has happened successful the past doesn't mean it volition hap again. Although it's historically expensive, the concern with today's S&P 500 isn't the aforesaid arsenic what we saw during the dot-com bubble oregon the 2022 carnivore market.

The dot-com bubble was fueled by wide speculation and by companies without existent net to warrant their valuations, and 2022 was a clip of inexpensive wealth and highly debased involvement rates that led galore investors to suffer show of imaginable risks.

Today, the costly marketplace is mostly fueled by the existent artificial quality roar and a fistful of megacap tech companies. That doesn't marque it immoderate amended -- conscionable different.

My proposal would beryllium to usage the dollar-cost averaging attack to investing close present -- oregon astatine immoderate time, for that matter. When you dollar-cost average, you enactment yourself connected a acceptable investing docket and instrumentality to it nary substance what. You could marque an concern each different Monday, each past Friday of the month, each clip you person a paycheck, oregon immoderate makes consciousness for your situation.
