By buying an index fund, investors can approximate the average market return. But if you pick the right individual stocks, you could make more than that. Just take a look at Bloomage BioTechnology Corporation Limited (SHSE:688363), which is up 52%, over three years, soundly beating the market return of 18% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 2.5% in the last year , including dividends .

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

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

During three years of share price growth, Bloomage BioTechnology achieved compound earnings per share growth of 16% per year. We don't think it is entirely coincidental that the EPS growth is reasonably close to the 15% average annual increase in the share price. This observation indicates that the market's attitude to the business hasn't changed all that much. Rather, the share price has approximately tracked EPS growth.
