Surfilter Network Technology (SZSE:300311) adds CN¥505m to market cap in the past 7 days, though investors from five years ago are still down 46%

It's nice to see the Surfilter Network Technology Co., Ltd. (SZSE:300311) share price up 23% in a week. But over the last half decade, the stock has not performed well. You would have done a lot better buying an index fund, since the stock has dropped 46% in that half decade.

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.

Given that Surfilter Network Technology didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. When a company doesn't make profits, we'd generally hope to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

In the last five years Surfilter Network Technology saw its revenue shrink by 12% per year. That puts it in an unattractive cohort, to put it mildly. It seems pretty reasonable to us that the share price dipped 8% per year in that time. This loss means the stock shareholders are probably pretty annoyed. It is possible for businesses to bounce back but as Buffett says, 'turnarounds seldom turn'.

Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 8% per year over five years.
