Last week’s chart illustrated the current plunge of S&P 500 earnings. Today’s chart illustrates how this plunge in earnings has impacted the current valuation of the stock market as measured by the price to earnings ratio (PE ratio). Generally speaking, when the PE ratio is high, stocks are considered to be expensive. When the PE ratio is low, stocks are considered to be inexpensive. From 1936 into the late 1980s, the PE ratio tended to peak in the low 20s (red line) and trough somewhere around seven (green line). The price investors were willing to pay for a dollar of earnings increased during the dot-com boom (late 1990s) and the dot-com bust (early 2000s). As a result of the current plunge in earnings and the recent 2.5 month stock market rally, the PE ratio has spiked to the low 120s – a record high.

Chart of the Day
While the stock market is up sharply since early March, the economy as well as corporate earnings continue to suffer. Today’s chart helps provide some perspective as to the magnitude of the current economic decline. Today’s chart illustrates that 12-month, as-reported S&P 500 earnings have declined over 90% over the past 20 months (with over 90% of S&P 500 companies having reported for Q1 2009), making this by far the largest decline on record (the data goes back to 1936). In fact, real earnings have dropped to a record low and if current estimates hold, Q3 2009 will see the first 12-month period during which S&P 500 earnings are negative.
