eFuture Information Technology provides software and services to retail and consumer goods industries in China. Before I started analyzing the company, the only thing I'd heard about them was the name. The company is based in China and has several Private Equity funds in shareholders. eFuture IT announced its quarter results on Thursday last week, the stock grew up on Friday and boomed on Monday. Now it's more than 75% up for today. What is behind such a rapid stock growth? In order to understand this jump, let's take a look at the company's financials and operating metrics:Revenue The company is generating its revenue from software sales, hardware sales and services fee, the last one is the most significant source of revenue. Last year the company had around $35M in revenue. Third quarter the company closed with $5.7M in Revenue, which is just 6% higher compared to the the same period last year. Moreover, for nine months the company had around $15M in revenue, which is 5% higher compared to 2014. I don't see that the company is going to boost their sales significantly this year, so I assume that that will be an organic growth. Interesting point is that the company decreased software and hardware sales and increased its services fees, I assume that this is not a good sign. It means that the company needs to invest more in its software and hardware in order to increase its revenue from its core business. Cost of revenue Cost of revenue for nine months of 2015 was around $6M, which is 5% higher compared to the same period last year. For three months, COGS was 6% higher. Nothing that could send the stock price to the sky yet. Operating expenses The company increased its operating costs by 18% for three months and 8% for nine months of 2015 compared to the same periods in 2014. As we assumes earlier, the company invested more money to research and development, an increase was around 118% for three months. However, R&D costs are less than 10% from all costs for nine months as of September 2015. In other words, we see the effect of low base. I am not sure that it an significantly influence on the ARPA and revenue.Operating metrics The company announced in its annual report that they got 122 new clients in 2014 and it was the main source of revenue growth. Another one was from current clients, they paid more in 2014. It seems that this year the company will have similar dynamic, so we cannot wait for the boom in operating metrics as well. The company slightly increased its marketing expenses which means that customer acquisition costs (in case if the number of new clients will be around the same figure) is more or less the same as in 2014. Unfortunately, I don't see any reasons for the stock to have such a huge jump as it has today. I assume that somebody tried to buy the higher volume than daily average and the market reacted instantly. I don't see any fundamental base for further growth. What should I know about eFuture?
