Generally speaking, investors are inspired to be stock pickers by the potential to find the big winners. But when you hold the right stock for the right time period, the rewards can be truly huge. Take, for example, the Carpenter Technology Corporation (NYSE:CRS) share price, which skyrocketed 420% over three years. Also pleasing for shareholders was the 27% gain in the last three months. But this could be related to the strong market, which is up 13% in the last three months.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During three years of share price growth, Carpenter Technology moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

It is of course excellent to see how Carpenter Technology has grown profits over the years, but the future is more important for shareholders. It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Carpenter Technology's TSR for the last 3 years was 445%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Carpenter Technology shareholders have received a total shareholder return of 168% over one year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 30% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. It's always interesting to track share price performance over the longer term. But to understand Carpenter Technology better, we need to consider many other factors.
