It is a pleasure to report that the Guanhao Biotech Co.,Ltd. (SZSE:300238) is up 72% in the last quarter. But if you look at the last five years the returns have not been good. In fact, the share price is down 29%, which falls well short of the return you could get by buying an index fund.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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 five years of share price growth, Guanhao BiotechLtd moved from a loss to profitability. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

Arguably, the revenue drop of 4.0% a year for half a decade suggests that the company can't grow in the long term. That could explain the weak share price.

A Different Perspective

It's good to see that Guanhao BiotechLtd has rewarded shareholders with a total shareholder return of 14% in the last twelve months. Notably the five-year annualised TSR loss of 5% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. It's always interesting to track share price performance over the longer term. But to understand Guanhao BiotechLtd better, we need to consider many other factors.
