As a new decade begins, it's a great time for investors to review the stocks in their portfolio. This is especially the case after a year of strong returns for the market. The S&P 500 climbed nearly 30% in 2019, which has left some stocks less attractive -- and others overvalued.
One stock that could help balance out a portfolio after such a bullish run is Telaria (NYSE: TLRA) -- a high-quality company that has largely flown under the radar and is trading at a bargain valuation. The sub-$400 million digital advertising specialist has strong fundamentals and a massive addressable market.
Not only is Telaria my top stock pick for 2020, but I'm also putting my money where my mouth is: The stock is my largest holding by a wide margin.
