PEG Ratio Reveals Significant Valuation Divergence
But before investors take this a cue to exit the stock market altogether, they need to take a closer look at what various valuation measures are saying. One popular measure, the price-to-growth or PEG ratio, is now indicating that a more complex reaction to the recent rally may be store for the markets than just a straight forward sell-off.

In simple terms, the PEG ratio is a stock's one year forward price-to-earnings ratio divided by its compound annual earnings growth rate, over that same time period. Its a useful way of evaluating the popular PE ratio, relative to expectations of future earnings growth. The lower this value, the more attractive the stock. Right now this measure is revealing some significant disparities between various sectors in the market.

Financials Appeared Overvalued; Defensives Look Cheap
Following average gains of nearly 150% since March's bottom, the financial sector is now sporting a lofty PEG ratio of 2.9-times, not so much because PEs for this group are high, but because future earnings growth prospects are viewed as quite low. In contrast, the healthcare, consumer staples and technology sectors appear to be more attractively priced with PEG ratios in the 1.4-1.5-times range. Analysts now see this groups as the likely beneficiaries of some buying interest at this juncture as investors trade of the momentum driven stocks in favor of the safety of these defensive groups.
