The 10% return this week takes China Aerospace International Holdings' (HKG:31) shareholders one-year gains to 29%

A diverse portfolio of stocks will always have winners and losers. But if you're going to beat the market overall, you need to have individual stocks that outperform. One such company is China Aerospace International Holdings Limited (HKG:31), which saw its share price increase 29% in the last year, slightly above the market return of around 25% (not including dividends). Zooming out, the stock is actually down 13% in the last three years.

Since the stock has added HK$123m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over the last twelve months China Aerospace International Holdings went from profitable to unprofitable. While some may see this as temporary, we're a skeptical bunch, and so we're a little surprised to see the share price go up. It may be that the company has done well on other metrics.

We think that the revenue growth of 11% could have some investors interested. Many businesses do go through a phase where they have to forgo some profits to drive business development, and sometimes its for the best.

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.
