If you’ve gotten out of bed in the past month, you’ve probably heard someone mention Alibaba (BABA). The Chinese ecommerce company is in the news this week after doing over $9 billion in gift sales on China’s “Singles’ Day.” With incredible growth numbers and hints of a future partnership with Apple, Alibaba’s stock has picked up tremendous steam and risen over 20% since its IPO.

This run up has led to many analysts reporting the stock as overvalued. However, an expensive stock can still be a good one if the business has the cash flows and growth to justify its stock price. If Alibaba is truly an undervalued stock, it could have serious room to run in the coming months. We’ll lay out some of the reasons that Alibaba might have the chops to back its stock price.

1. It’s Big — Really Big

Alibaba handles close to eighty percent of ecommerce in China, totaling $240 billion in sales in 2013. These sales amounts are double the volume handled by Amazon in the U.S. Alibaba has 307 million active users, roughly equal the population of the United States. In terms of market cap, it ranks above companies like General Electric (GE) and Wal-Mart (WMT).

2. It’s Growing

Despite its size, Alibaba’s potential for growth is still enormous. Analysts estimate that around 600 million Chinese citizens have Internet access, or 46% of the country’s population. Over, 82% of U.S. consumers are connected to the Internet, which means that there are hundreds of millions of potential customers that Alibaba has yet to reach. The company’s first quarterly report from early November showed revenue increases of 54%, sending the stock up 4%.

3. It’s Diversifying

Alibaba has its own online payment platform with over 300 million users. This system gives it control of just under half of the online payment market in China. Alibaba also has its own money market fund called Yu’E Bao, which has been purchasing equity in soccer clubs, hotel tech companies, mobile game makers, online video companies, and travel websites.
