Key Points:
- The S&P 500 forward price-to-earnings ratio dropped to 19.7 times, which sits below its 5-year average of 20.1 times.
- The valuation gap between the Nasdaq 100 and the S&P 500 reached its narrowest point since December 2018.
- Historical data show the stock market usually posts strong gains when these specific valuation metrics fall this low.
- Implied volatility for major technology stocks like Nvidia and Tesla dropped to some of the lowest levels seen this year.
Stock valuations across the United States market recently experienced a massive reset. Both the S&P 500 and the Nasdaq now trade at the lower end of their recent price ranges. Scott Rubner, the head of equity and equity derivatives strategy at Citadel Securities, outlined this major shift. He noted that the sudden drop in prices gives investors a rare chance to buy shares at much cheaper levels than they could earlier this year.
The S&P 500 forward price-to-earnings ratio currently sits at roughly 19.7 times. This number rests comfortably below the 5-year average of 20.1 times. The ratio also ranks in the 6th percentile of its 1-year range. Stock prices have not looked this cheap since April 2025, right around Liberation Day. Investors often watch this specific ratio to decide whether the broader market is overvalued or offers a good deal.
History shows that buying stocks when they get this cheap usually works out well for investors. Rubner explained that whenever the S&P 500 forward ratio drops below 20 times, future market returns generally look very positive. Since 2020, the index has broken below this specific threshold exactly 13 times. After those drops, the market delivered an average 30-day return of 3.5% and a median return of 6.4%. Overall, the market posted positive returns 75% of the time after hitting this low point.
The technology-heavy Nasdaq 100 also looks incredibly cheap right now. The forward price-to-earnings ratio for the Nasdaq recently declined to about 21.7 times. This falls well below its 10-year average of 22.8 times. The metric now sits in just the 2nd percentile over the past year and the 13th percentile over the past 5 years. Technology stocks took a heavy beating recently, dragging valuations to rock bottom.
One of the most interesting changes involves the valuation gap between the two major indexes. The difference between the Nasdaq and the S&P 500 forward ratios shrank dramatically over the past few weeks. This spread now sits at roughly 2.0 times, marking its narrowest level since December 2018. On Friday, the spread closed below 2.0. This rare event puts the gap in the bottom 20% of its 10-year historical range.
Financial experts closely monitor this shrinking gap because it often signals a strong buying opportunity for technology stocks. Over the past 20 years, the market saw only 30 instances in which this spread fell below 2.0. In the 30 trading sessions following those specific events, the Nasdaq 100 delivered average and median returns of 2.7%. The tech index rallied 76% of the time and consistently outperformed the S&P 500 over the same period.
While stock prices look cheap, overall market volatility remains slightly elevated. However, the wild price swings recently started to calm down. For example, the 1-month implied volatility for the popular QQQ fund currently sits in the 85th percentile of its 1-year range. This marks a solid drop from the 93rd percentile recorded just last Friday. As fear leaves the market, stock prices often find a stable floor.
Several massive technology companies also saw their individual volatility levels crash. The 1-month 25-delta call implied volatility for Nvidia recently plummeted to the 3rd percentile of its 1-year range. This huge drop happened even though Nvidia accounts for about 8% of the massive SPY fund, which still shows its own volatility sitting way up in the 90th percentile.
The same calming trend appears across almost every other major technology stock on Wall Street. Tesla’s 1-month implied volatility dropped to the 6th percentile. Palantir fell to the 10th percentile, while Google settled in the 20th percentile. Broadcom also dropped to the 25th percentile of its respective 1-year range. With prices resetting and fear fading quickly, the stock market looks ready for its next big move higher.
