A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -13.3%. They describe history only and say nothing certain about the share price ahead.
