The main aim of stock picking is to find the market-beating stocks. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term Ecovyst Inc. (NYSE:ECVT) shareholders for doubting their decision to hold, with the stock down 37% over a half decade. But it's up 6.5% in the last week.

The recent uptick of 6.5% could be a positive sign of things to come, so let's take a look at historical fundamentals.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the five years over which the share price declined, Ecovyst's earnings per share (EPS) dropped by 5.5% each year. This reduction in EPS is less than the 9% annual reduction in the share price. This implies that the market was previously too optimistic about the stock.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. It might be well worthwhile taking a look at our free report on Ecovyst's earnings, revenue and cash flow.

What About The Total Shareholder Return (TSR)?

Investors should note that there's a difference between Ecovyst's total shareholder return (TSR) and its share price change, which we've covered above. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. We note that Ecovyst's TSR, at -12% is higher than its share price return of -37%. When you consider it hasn't been paying a dividend, this data suggests shareholders have benefitted from a spin-off, or had the opportunity to acquire attractively priced shares in a discounted capital raising.

A Different Perspective

Investors in Ecovyst had a tough year, with a total loss of 10%, against a market gain of about 20%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
