Complete novice here - am I right that Guardant is one to watch?

Hello! I'm a complete beginner, so I just want to see if my process is right or way off. Guardant is a player in highly anticipated precision health market. I ran a stochastic oscillator and it looks like the asset is just coming out of a long period of oversold levels (literally about to come over the 20% mark as of 12 April 2021) and looks like the time to buy for that reason. To temper that a little, I looked at the Price Volume Trend (Investopedia says this is the right thing to do to best avoid false signals), and it showed a slight but stable looking increase. Makes me think that it's one to watch carefully to see where this goes. If I'm way off - what should I be looking at instead?
