Despite the downward trend in earnings at ZONQING Environmental (HKG:1855) the stock surges 13%, bringing five-year gains to 133%

The last three months have been tough on ZONQING Environmental Limited (HKG:1855) shareholders, who have seen the share price decline a rather worrying 52%. But that scarcely detracts from the really solid long term returns generated by the company over five years. It's fair to say most would be happy with 132% the gain in that time. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Ultimately business performance will determine whether the stock price continues the positive long term trend. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 77% decline over the last twelve months.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

A Different Perspective

ZONQING Environmental shareholders are down 77% for the year, but the market itself is up 38%. 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. On the bright side, long term shareholders have made money, with a gain of 18% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
