Statistically speaking, long term investing is a profitable endeavour. But that doesn't mean long term investors can avoid big losses. For example the BWX Limited (ASX:BWX) share price dropped 56% over five years. We certainly feel for shareholders who bought near the top. We also note that the stock has performed poorly over the last year, with the share price down 54%. Shareholders have had an even rougher run lately, with the share price down 50% in the last 90 days.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Looking back five years, both BWX's share price and EPS declined; the latter at a rate of 14% per year. Notably, the share price has fallen at 15% per year, fairly close to the change in the EPS. This implies that the market has had a fairly steady view of the stock. Rather, the share price change has reflected changes in earnings per share.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What about the Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between BWX's total shareholder return (TSR) and its share price return. Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. BWX's TSR of was a loss of 52% for the 5 years. That wasn't as bad as its share price return, because it has paid dividends.



A Different Perspective

BWX shareholders are down 54% for the year, but the market itself is up 14%. 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 9% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Take risks, for example - BWX has  3 warning signs  we think you should be aware of.
