The strike is at $5.5. Warrants provide 'leverage', so yes the movement will be increased in either direction...Up or down. Given their insanely good quarter, I highly highly doubt the common will get back to $9 but anything is possible.
The common has to be trading above $11.50 for 20-out-of-30 trading days for them to issue the 30-day redeem notice. For that 'criteria' to start, the warrants must be exercisable (which they are not at this time).
Once they issue the redeem notice, if during that 30-day window the common goes down like you suggest, then yes we may see a movement like that for the warrants.
Of course, your cost to buy-in to the common will always remain the $5.5 strike price, so you can always exercise and wait for it to recover back to $13+...but it may require capital outley to do so.
