Lumia 520 came back in stock at official Jingdong mall in China after getting sold out for 3rd time. Now, while other two colors are still in stock, Yellow Lumia 520 is sold out for the 4th time in a row now. This is encouraging as it indicates strong traction for Lumia 520, but little worrying is the fact that Nokia is not able to cope up with the demand. This “out of stock” situation shouldn’t persist for long if Nokia has to take real advantage of such strong demand in big markets like US, India, China and others.

May be Nokia is still treading with bit caution and is not trying to dump market with millions of Lumia 520. But while that strategy has been fine with Q4 and Q1, now is the time to scale up the production for Lumia. After all Nokia need to pump volumes in the market, if they want their volume drivers (Lumia 520) to win significant market share.

Indications from markets like India have been really good, where in spite of going out of stock  several times at many retailers including Flipkart and Nokia shop, Lumia 520 is now the best-selling Windows phone ever just one month in release.
