Masimo Corp. (NASDAQ:MASI) has had a good run going this year. I have to admit that I had a lot of fun trading this stock as a paper trade. I bought it in my simulator in November and sold out in February at about $85. But MASI’s financials have started to stagnate, and it missed on its May 3rd earnings report. That caused it to drop like a rock on May 4th. So is MASI now a buy, hold or sell? Let’s look at the data and see what it tells us.
