$AMD(AMD)$A $50,000 investment in shares of AMD at the beginning of 2012 was worth more than $1.3 million at the end of 2021. Of course, the stock has pulled back 42% so far in 2022, but investors who bought the company's shares a decade ago are still sitting on fat gains.The good part is that AMD's slide this year has made the stock attractive as far as its valuation is concerned. The stock's price-to-earnings (P/E) ratio of 31 is way lower than its five-year average earnings multiple of 105. The forward P/E of 20 points toward healthy growth in AMD's bottom line over the next year.More importantly, a closer look at the markets that AMD serves tells us that this company could grow at an impressive pace for years to come.
