$Upstart Holdings, Inc.(UPST)$ Okay so according to Peter Lynch, the P/E ratio of any company that's fairly priced will equal its growth rate. If the P/E of Coca-Cola is 15, you'd expect the company to be growing at about 15 percent a year, etc. Upstart Holdings has a p/e ratio of 171 and an earnings grow rate of 200 percent per year or a PEG ratio of 0.85 which means that wall street will still pay up more for this stock. Unless the forward P/E and earnings growth has suddenly made a drastic downturn this stock could be considered a bargain and should be trading much higher than this price
