Glossary

"A bear market should not be  confused with a correction, which is a short-term trend that has a  duration of less than two months. While corrections are often a  great place for a value investor to find an entry point, bear markets rarely  provide great entry points, as timing the bottom is very difficult to do.  Fighting back can be extremely dangerous because it is quite difficult for  an investor to make stellar gains during a bear market unless he or she  is a short seller."
