Despite delivering investors losses of 53% over the past 3 years, Delta (NSE:DELTACORP) has been growing its earnings

Delta Corp Limited (NSE:DELTACORP) shareholders should be happy to see the share price up 11% in the last month. But that is small recompense for the exasperating returns over three years. In that time, the share price dropped 54%. So it's good to see it climbing back up. After all, could be that the fall was overdone.

While the stock has risen 10% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Although the share price is down over three years, Delta actually managed to grow EPS by 27% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Alternatively, growth expectations may have been unreasonable in the past.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The modest 1.3% dividend yield is unlikely to be guiding the market view of the stock. We think that the revenue decline over three years, at a rate of 9.4% per year, probably had some shareholders looking to sell. And that's not surprising, since it seems unlikely that EPS growth can continue for long in the absence of revenue growth.

A Different Perspective

While the broader market lost about 5.8% in the twelve months, Delta shareholders did even worse, losing 26% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.0% 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. 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.
