Is it time to load the boat?

I've been adding more at these low prices to lower my cost basis. I note Square on NYSE has been on a tear lately. I know they aren't exactly the same business, but i feel that TYR should trend inline with SQ.
My concern with TYR is that they are still pretty vulnerable to reduced turnover in the short term and retail clients closing up shop. Renting out POS equipment reduces client stickiness and thy aren't yet big enough to rely on momentum. However, so far it seems like the business is holding up much better that it's share price reflects. I'm tempted to dip into margin loan and throw big money at it.
