I recently have bought SAVE, ACI, CPRI, and SGEN
I was also looking on USM/TDS, and IRBT, but biting my neils.. TDS/USM has no announced deals and founder recently gifted his family a lot of shares. IRBT got objection letter from EC.
The new FTC regime is making arbs more interesting, and more profitable, imo. They are seems keep losing trials.
