There's plenty more volatility to come. Royal Bank was up 13% today. In an environment where the largest and most solid bank stock in the country can be +/- 10% in a day, an even more sensitive stock like AC can be up and down way more.

AC will likely take big falls on days where travel restrictions are broadened or extended, big ups on days when they're removed/reduced, and a big up any day when a bailout looks like it's close to happening.

Can't say for sure it will get back to $12, but it's not unlikely.
