Apple announced the iPhone in January 2007. This window runs from March 15, 2007, two months later, through the June launch and the holiday quarter, and ends on December 27, 2007. Close to close it is +121.6%. The low is session 1. A later pullback reaches −19.8%, and the worst day is November 12, 2007 at −7.0%. The two halves are almost even: +50.7%, then +47.1%.
What you trade
Buy and hold finishes at +121.6%, with a −19.8% drop from a high along the way. The first 100 sessions are +50.7% and the last 100 are +47.1%. The benchmark is already a strong result, so beating it means staying with the move and surviving the worst session, November 12, 2007, which moves −7.0%.
This page names Apple because this challenge is that company. The daily puzzle and a random practice game keep the company hidden. Inside this round the chart still hides the name and the dates until you finish.
