The P/E ratio was exceptionally high in 2009 primarily because corporate earnings had plummeted to historic lows during a severe economic recession, despite the overall stock market experiencing a significant crash.
Understanding the P/E Ratio
The Price-to-Earnings (P/E) ratio is a fundamental valuation metric used by investors to determine the relative value of a company's stock. It is calculated by dividing the current share price by the company's earnings per share (EPS).
- Formula:
P/E Ratio = Share Price / Earnings Per Share
A high P/E ratio typically indicates that investors are willing to pay a higher price for each dollar of earnings, often reflecting expectations of strong future growth. Conversely, a low P/E ratio might suggest that a company is undervalued or that its future growth prospects are limited. However, during periods of extreme economic distress, the P/E ratio can become distorted.

The Economic Landscape of 2009
The year 2009 was marked by the lingering effects of the 2008 financial crisis, which triggered one of the most severe economic downturns in modern history, known as the Great Recession. This period was characterized by:
- Stock Market Crash: The stock market had experienced a dramatic decline from its 2007 peaks, significantly reducing stock prices.
- Severe Recession: Businesses faced immense challenges, including reduced consumer spending, credit market freezes, and widespread uncertainty. This led to a sharp contraction in economic activity.
The Impact of Low Earnings on P/E
Despite the drop in stock prices, corporate earnings fell even more dramatically. Earnings are the denominator in the P/E ratio calculation. When earnings (E) become extremely low, even if the stock price (P) has fallen, the resulting P/E ratio can become astronomically high.
Consider this simplified illustration:
| Scenario | Share Price (P) | Earnings Per Share (E) | P/E Ratio (P/E) |
|---|---|---|---|
| Normal Market | $100 | $5 | 20x |
| 2009 Recession | $50 | $0.50 | 100x |
In 2009, many companies saw their profits shrink significantly or even turn into losses. This made the "E" in the P/E calculation so small that, for many companies and the market as a whole, the ratio appeared "off the charts" high. This reflected the dire state of corporate profitability rather than an overvaluation of stock prices themselves.
Long-Term Perspective for Investors
Interestingly, even though the P/E ratios were elevated due to depressed earnings, the stock market ultimately proved to be quite cheap from a long-term perspective. Investors who bought stocks during this period, despite the high P/E ratios, often realized substantial returns over the subsequent decade. This highlights an important nuance in valuation: while P/E is a crucial metric, it must be interpreted within the broader economic context and understood that historically low earnings can temporarily inflate the ratio, even when stock prices are fundamentally low.
