The most successful investors identify strong stocks and own them for the long run. That’s hard to do with many companies because volatile business models can make it dangerous to hold onto shares without paying close attention to short-term performance. With Visa (NYSE: V), Starbucks (NASDAQ: SBUX), and Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL), however, consistent strength in the way that each company operates its business and makes steady advances to maintain its leadership role makes them great prospects for buy-and-hold investors.
