The past five years for Lucapa Diamond (ASX:LOM) investors has not been profitable

Some stocks are best avoided. We really hate to see fellow investors lose their hard-earned money. Spare a thought for those who held Lucapa Diamond Company Limited (ASX:LOM) for five whole years - as the share price tanked 82%. Furthermore, it's down 37% in about a quarter. That's not much fun for holders. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Lucapa Diamond became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

Revenue is actually up 63% over the time period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

A Different Perspective

Lucapa Diamond shareholders are down 5.5% for the year, but the market itself is up 4.6%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 13% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Take risks, for example - Lucapa Diamond has 4 warning signs (and 1 which can't be ignored) we think you should know about.
