Chinese mobile communications giant China Mobile (CHL) once again is today’s top mover by market capitalization.

China Mobile Ltd. [[CHL]]had a strong trading day Monday, gaining more than $4.53 billion in market capitalization on the heels of Friday’s $4.37 billion gain. China’s largest cellular company by subscribers is perhaps up on the momentum provided by a number of significant analyst upgrades for Chinese mobile companies – China Telecom Corp. [[CHA]] and China Unicom [[CHU]] were both upgraded from “Hold” to “Buy” – as well as general bullishness on the state of the Chinese economy which has helped China Mobile shares gain more than 22% over the last month.

China Mobile (CHL) and China Petroleum & Chemical Corp. (SNP) are the top Chinese movers of the day by market capitalization, though shares of these giants in moved in opposite directions.

China Mobile Ltd. [[CHL]] gained more than $4.37 billion in market capitalization Friday as shares gained 1.94%. Shares of China’s largest cellphone company moved on news that its new online application store, Mobile Market, would go live this month.

China Petroleum & Chemical Corp. [[SNP]] lost more than $2.31 billion in market capitalization Friday as shares lost 2.95%. The company better known as Sinopec was particularly hard hit on a day that was generally bad for energy companies. The energy sector lost 0.28% of its value with PetroChina Company Ltd. [[PTR]] and CNOOC Ltd. [[CEO]] also down.

China Mobile (CHL) is today’s top Chinese stock mover, adding more than $5.4 billion in market capitalization.

China Mobile Ltd. [[CHL]], China’s largest cellphone company which can brag it has more subscribers than the U.S. has citizens, is up more than 7% over the last five days. Today the company added more than $5.49 billion in market capitalization thanks to its 4 billion outstanding shares.

It was announced today the China Mobile is partnering with China Telecom [[CHA]] to battle the Apple [[AAPL]] iPhone. The iPhone is going to be exclusively offered by China Mobile’s smaller competitor China Unicom [[CHU]], in a coup for the company. China Mobile and China Telecom plan on offering the “OPhone,” which Lenovo Group is helping to develop based on Google’s [[GOOG]] Android operating system for cellphones. The OPhone will even have its own version of the iPhone’s “App Store” named MobileMarket.
