I do not think we know accurately how high Matic will increase. The only thing you can do is just set your target price and wait for a while. Let the pump still go on for Matic and if the pump is not reached your target price, you do not have to do anything.

You can buy back Matic if you want but you should wait for the next correction after the pump. Maybe Matic can break $5-$10 but we do not know how long that will happen. You can buy and hold it if you do not want to see the price go up and down.
