Ingevity Corporation (NYSE:NGVT) shareholders will doubtless be very grateful to see the share price up 47% in the last quarter. But that doesn't change the fact that the returns over the last three years have been less than pleasing. After all, the share price is down 28% in the last three years, significantly under-performing the market.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Ingevity has made a profit in the past. On the other hand, it reported a trailing twelve months loss, suggesting it isn't reliably profitable. Other metrics may better explain the share price move.

We think that the revenue decline over three years, at a rate of 3.1% per year, probably had some shareholders looking to sell. And that's not surprising, since it seems unlikely that EPS growth can continue for long in the absence of revenue growth.

A Different Perspective

Ingevity shareholders gained a total return of 2.7% during the year. But that return falls short of the market. But at least that's still a gain! Over five years the TSR has been a reduction of 4% per year, over five years. It could well be that the business is stabilizing. 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.
