The stock, after a strong run-up for several months,
reaches a "climax top" in which the price suddenly goes up even faster —
25% to 50% or more on heavy volume in a couple of weeks. The price
spread for the week will be greater than on any prior week since the
beginning of the stock's major move. Sometimes this run will finish with
the stock's largest single-day advance since it began moving up. As the
name implies, this is a situation when a buying spree in a stock becomes
too obvious and everyone is excited by the price action.
