While it may not be enough for some shareholders, we think it is good to see the The Hain Celestial Group, Inc. (NASDAQ:HAIN) share price up 14% in a single quarter. But the last three years have seen a terrible decline. To wit, the share price sky-dived 82% in that time. So we're relieved for long term holders to see a bit of uplift. The thing to think about is whether the business has really turned around. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.
