When does a low PE ratio not indicate a good stock?
Some companies have a steady, reliable, stream of earnings. In that case, a low P/E ratio is likely to indicate a good stock. Other companies have a "feast or famine" pattern, great earnings one year, no earnings or losses the following year. In that case, it is misleading to use a P/E ratio for a good year, when earnings are high and the ratio is low. Instead, you have to figure out what the company's AVERAGE earnings may be for some years, and assign a P/E ratio to that.
