A Different Perspective

Del Taco Restaurants provided a TSR of 25% over the year (including dividends). That's fairly close to the broader market return. That gain looks pretty satisfying, and it is even better than the five-year TSR of 0.2% per year. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
