Apple shares are still "on sale." The price will certainly rise back to the 52 week highs "when the dust settles." Yep, that may be a few months, but it will happen as it always does after an earnings report.
Some companies used to start their fiscal year on April 1. Not sure why, but they did. Others start their fiscal years at different times. I guess a lot depends on when they were founded and what was convenient way back when they started doing that.
Companies that have large payrolls, large numbers of employees, will be snowed under during December and January in the USA taking care of the tax requirements mandated by the government which are related to employees. It is probably easier to move their fiscal year start date away from the first of the year so they don't have to take care of both at the same time.
