Alkermes (NASDAQ:ALKS) shareholders have earned a 9.3% CAGR over the last five years

When you buy and hold a stock for the long term, you definitely want it to provide a positive return. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the Alkermes plc (NASDAQ:ALKS) share price is up 54% in the last five years, that's less than the market return. Over the last twelve months the stock price has risen a very respectable 20%.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

What About The Total Shareholder Return (TSR)?

We've already covered Alkermes' share price action, but we should also mention its total shareholder return (TSR). Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. Alkermes hasn't been paying dividends, but its TSR of 56% exceeds its share price return of 54%, implying it has either spun-off a business, or raised capital at a discount; thereby providing additional value to shareholders.

A Different Perspective

It's nice to see that Alkermes shareholders have received a total shareholder return of 20% over the last year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 9% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
