UEPS has completed the acquisition of a payroll processor for cash and the stock has held up well indicating the market thinks it may be a wise move. There are definitely some possible synergies with the primary business of payment processing.
Keep an eye on UEPS, LFT, and even YTEC (ugh). ACXM and ARMH have run way up. I expect others in the tech sector to follow barring a general market breakdown.
