Key insights
- The article highlights that the S&P 500's CAPE ratio is at levels not seen since 1999, suggesting potentially negative annualized returns over the next 10 years based on historical data. While acknowledging bullish factors like technology dominance and passive inflows, the high valuation warrants caution for investors. The overall tone leans bearish due to valuation concerns.
The S&P 500 index (^GSPC +0.80%) continues to prove the bears wrong. The benchmark's level has risen 8% in April (as of April 22). And it has produced a total return of 300% in the past decade.
After such a phenomenal performance that's significantly better than its average historical return of 10%, investors might consider being cautious. The stock market just did something it hasn't done since the dot-com bubble period of 1999.
History provides a clear answer as to what might happen next.
According to the CAPE ratio of 40.1, the S&P 500 is extremely expensive these days. The last time this popular valuation metric was this high was in 1999, before this century even started.
Research conducted by Invesco, which analyzes the relationship between starting CAPE ratios and forward returns, reveals a possibly bleak future. When the CAPE ratio is this high, the S&P 500's annualized gains over the following 10 years can be negative.
Before you rush to sell your entire portfolio, it's worth thinking about the bullish case. The market's powerful tailwinds, like major contribution from dominant technology enterprises, huge capital inflows from passive investors, and ongoing currency debasement, will keep propelling it for the foreseeable future.
While it's always a smart move to keep valuation in mind, it's also important to be optimistic about the long term.
