Finding quality companies that aren't already on Wall Street's radar is challenging since investors tend to take notice of businesses doing extraordinary things. That said, under-the-radar candidates can sometimes be found behind the scenes. Three companies for your watch list include niche payments-network company WEX (NYSE: WEX), manufacturing enabler MKS Instruments (NASDAQ: MKSI), and identity software player LiveRamp Holdings (NYSE: RAMP).
All three of these companies are growing, and hardly anyone has noticed. That oversight could be your opportunity.
