What happened Shares of NXP Semiconductors (NASDAQ: NXPI) rose 18.8% higher in January 2019, according to data from S&P Global Market Intelligence. The maker of embedded semiconductors generally floated along with a rising market but also took a bigger leap mid-month, when a buyout rumor made the rounds. So what According to South Korean investing site Invest Chosun, local tech giant Samsung (NASDAQOTH: SSNLF) was thinking about a buyout bid for NXP. The deal would boost Samsung's toehold in the market for automotive computing chips and NXP investors would finally realize the buyout exit that Qualcomm (NASDAQ: QCOM) never quite could finalize over the past three years.

This close to the collapse of the Qualcomm deal, NXP's management and investors should be skeptical of another big-ticket merger proposal. That being said, NXP's share prices held on to their rumor-boosted gains throughout January and saw another modest jump on a solid earnings report last week. The stock is up by 21.5% in 2019 and still looks like a fantastic deal next to the popped $44 billion Qualcomm bid or a forward P/E ratio of less than 10. I don't think it'll take a Samsung-backed buyout to squeeze some solid gains out of this undervalued stock. 10 stocks we like better than NXP SemiconductorsWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
