The shape of this chart

Yahoo from March 1, 2013 to December 12, 2013 opens on its low, session 1, and finishes +79.4%. The second hundred sessions (+41.3%) do more than the first (+26.9%). There is one air-pocket: a −12.0% drop that bottoms on June 24, 2013, the same day as the worst session (−4.5%). Alibaba was still private in 2013, so this tape is the US listing, a climb with a single scare in June.
