Ideally, your overall portfolio should beat the market average. But even the best stock picker will only win with some selections. At this point some shareholders may be questioning their investment in Garrett Motion Inc. (NASDAQ:GTX), since the last five years saw the share price fall 24%. Shareholders have had an even rougher run lately, with the share price down 11% in the last 90 days.

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

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Garrett Motion became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics may better explain the share price move.

In contrast to the share price, revenue has actually increased by 4.9% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

A Different Perspective

Garrett Motion provided a TSR of 3.6% over the last twelve months. But that was short of the market average. But at least that's still a gain! Over five years the TSR has been a reduction of 4% per year, over five years. So this might be a sign the business has turned its fortunes around. 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.
