Stock market indicators, the simplest being bull and bear markets, are numbers that investors use
to support various investing theories. When certain numbers are rising or falling or high or low,
these people believe that there is a clear meaning attached.
I won't discuss the many stock selection theories based on the various market indicators, but there
are hundreds of books available to you if you are truly interested. More than one experienced
investor has remarked that "trend lines, up/down volume, buying pressure vs. selling
pressure, stochastic indicators, over-bought/over-sold indicators, new highs/new lows, put/call
volume ratio, and moving averages are mainly a waste of time. They can mislead you and cost you a
lot of money".
