SwingNav's Month-End Valuation: The September PE Ratio
SwingNav's September Valuation
The closing bell has rung, marking the end of the third quarter. As the market digests the past month, a key question for every serious trader is: Where does market valuation stand?
Here is SwingNav's uniquely calculated 4Q Forward PE Ratio for the stock market, as of today's close on September 30, 2025.
Today's 4Q Forward PE Ratio: 21.53
SwingNav's Insight
A PE Ratio of 21.53 indicates that valuations are stretched and are at the high end, historically. From our holistic perspective, this suggests a potential lack of future earnings growth, and could be an early indicator of a future correction. However, the market has sustained high P/E ratios for long periods in the past, and it could be due to a strong underlying momentum in the market.
Why This Ratio Matters
At SwingNav, our 4Q Forward PE Ratio is a crucial input into our daily market oscillators. We've developed a fresh approach to this traditional metric by incorporating two key adjustments that provide a clearer and more dependable valuation signal:
1. Time-Smoothed Earnings: We smooth out the abrupt jumps in forward earnings estimates that occur with each new quarter, giving you a more consistent and higher-conviction read on the market's true valuation trend.
2. Surprise-Adjusted Forecasts: We estimate earnings surprises based on historical and current trends to provide a more realistic earnings outlook, helping to minimize distorted valuation readings.
