"Regarding that target, mathematics says that the share price as of now on average gained 1.42 percent each calendar day this year. IF (bold, italic, underlined capitals) the share price can sustain this rate, we'll hit the $70 target around December 12th this year."

LOL, thats funny Andrea. I did the same calculation and I think you may have included weekends accidentally unless your 1.42 is not per trading day. :)
