The five-year shareholder returns and company earnings persist lower as Nemak S. A. B. de C. V (BMV:NEMAKA) stock falls a further 15% in past week

Long term investing works well, but it doesn't always work for each individual stock. We don't wish catastrophic capital loss on anyone. For example, we sympathize with anyone who was caught holding Nemak, S. A. B. de C. V. (BMV:NEMAKA) during the five years that saw its share price drop a whopping 81%. And we doubt long term believers are the only worried holders, since the stock price has declined 55% over the last twelve months. Shareholders have had an even rougher run lately, with the share price down 22% in the last 90 days. We really feel for shareholders in this scenario. It's a good reminder of the importance of diversification, and it's worth keeping in mind there's more to life than money, anyway.

If the past week is anything to go by, investor sentiment for Nemak S. A. B. de C. V isn't positive, so let's see if there's a mismatch between fundamentals and the share price.
