Commodities prices are at their lowest in six weeks, reports Chanyaporn Chanjaroen of Bloomberg. Could this be a good time to buy? Or is it a sign that commodities have been too expensive and that prices will continue to fall?

Increases in perceived risk have caused commodities to rise sharply over the past year. Oil prices have skyrocketed due to turmoil in the Middle East and other economic risks. Investors have flocked to precious metals in a "flight to safety" from other riskier investments. Moreover, sovereign-debt problems, particularly in Greece, are causing people to fear a completely new slowdown.

"The major influence continues to be the European situation ... If you look at what happened to the oil price during the financial crisis you can see that these events have a big impact. There is this tone of a global slowing in the economy," Ben Westmore of Australia Bank Ltd. told Bloomberg.

Yet several fund managers are bullish on commodities in the long run. They foresee rising demand from the developing world, which will support higher prices, according to Jonathan Bloomberg of MarketWatch.

If you agree with their bullish long-term view and are looking for cheap commodity stocks, here is a list of stocks that appear undervalued according to their price to earnings growth (PEG) ratios.

The PEG ratio is a measure of how much investors are paying for annual earnings (EPS) growth.

PEG = (P/E)/(Annual EPS Growth)

When a company looks overvalued because of a high P/E, taking into account earnings growth can standardize the measure, giving a ratio that is more comparable across firms. PEG ratios above 1 are seen as overvalued, whereas PEG's below 1 appear undervalued.
