Dunkin' Brands (NASDAQ:DNKN) has been in an epic uptrend since it made its lows at $35 at the start of the year. The stock has flown from that level to just over $50 in 2016, and heading into Q3 results, due out next week, it seems sentiment is very high. DNKN has managed to continue to grow despite its massive size and obvious competition from the likes of Starbucks (NASDAQ:SBUX), but has it earned the right to trade for $50 again? Going into Q3 earnings, I'm a bit cautious on the stock's valuation, but let's take a look at what might drive it higher or lower.
