Capital market analysts said recovery in fundamentals will help China's liquor makers to improve their financials.

Shares of liquor companies may grow faster than those of many other sectors this year, they said.

A research note from Sealand Securities Co said increasing fixed-income investments and a rising Consumer Price Index will help lift shares of liquor makers, particularly those that have been oversold.

According to Shanghai WIND Information Technology Co, the average share price of 21 A-share liquor makers has grown more than 10 percent since the beginning of February, more than double that of the benchmark index.
