Line chart showing BlackBerry shares falling 14.23 percent on Thursday after a months-long rally.

BlackBerry's 14.23% Thursday drop to $12.84 followed a months-long rally built on QNX automotive software momentum. The reversal came after two executives moved to sell beforehand: the CEO filed to sell shares on July 8, and the chief legal officer sold 30,000 shares for $339,600 on July 14. Research on investor behaviour after a strong run of gains finds that traders tend to read the streak itself as proof of skill rather than luck.
