Dollar Tree (NASDAQ: DLTR) has had its share of issues over the last several years. However, investors have clearly warmed up to the company, and the stock has gained 52% over the past year, besting the S&P 500's 48% increase.
The key question is whether the company has truly turned the corner, leaving a lot of upside potential for long-term stock investors, or if Dollar Tree benefited from extenuating circumstances. That's why it's important to look closer at its business.
