===Market top===
A market top (or market high) is usually not a dramatic event. The market has simply reached the highest point that it will, for some time. This identification is retrospective, as market participants are generally unaware of it when it occurs. Thus prices subsequently fall, either slowly or more rapidly.

According to [[William O'Neil]], since the 1950s, a market top is characterized by three to five distribution days in a major [[stock market index]] occurring within a relatively short period of time. Distribution is identified as a decline in price with higher volume than the preceding session.<ref>{{cite web |url=https://www.investors.com/how-to-invest/investors-corner/know-this-sell-rule-when-distribution-days-pile-up-in-the-stock-market/ |author=David Saito-Chung |title=Know This Sell Rule: When Distribution Days Pile Up In The Stock Market |date=8 November 2016 |publisher=Investors.com}}</ref>
