NEW YORK ( TheStreet) -- China Sky One Medical ( CSKI) and Skystar Bio-Pharmaceuticals ( SKBI) have strong domestic growth and attractive price multiples and because of recent selloffs could outperform U.S. pharmaceutical giants Pfizer ( PFE) and Merck ( MRK) during the upcoming months.China's massive population of 1.3 billion people, aggressive government spending on health care and accelerating demand for drugs, and improving investments from multinational companies, will help the country's pharmaceutical industry register a compound annual growth rate of close to 20% for a decade, a substantial long-term growth outlook. China is likely to emerge the third-largest health care market by 2011, according to IMS Health. China Sky manufactures pharmaceutical, medical products and diagnostic kits. Skystar Bio-Pharmaceutical manages a biopharmaceutical research and development center and production business. These two Chinese stocks have been undervalued as they are relatively unknown to investors and experience home-bias from U.S. investors. Revenue growth of the two companies in comparison to Pfizer and Merck is staggering. China Sky's revenue grew at a CAGR of 87% to $130.1 million in 2009 from $19.88 million in 2006, and Skystar's revenue grew at a CAGR of 54.4% to $33.8 million in 2009 from $5.94 million in 2005.

China Sky and Skystar lost 47.3% and 29.6% of their respective market values year to date, and hence provide attractive bargaining opportunities.

Meanwhile, China Sky and Skystar are trading at attractive price-to-earnings ratios of 5.65 and 4.79, respectively, in comparison to Pfizer's 6.71 and Merck's 10.63.
