A-shares were on the rise last week with Shanghai Composite closed 1.8% higher at 3196.7 points.

The rising trend is largely due to a temporary slowdown of IPOs. Though the central bank is draining money from the market, the market remains liquid at the moment. But it is likely to reintroduce reverse repos as 900 billion yuan (130.62 billion US dollars) of contracts are set to mature this week.

I think lowering deposits reserve ratio is also a good way to ease liquidity concern. Statistics show that China's exports and imports rise steadily in January. In addition, dollar remains weak on the whole, at least in the short term. Therefore I think it is the right time to do so.

Investors can take advantage of shares of enterprises involving Belt and Road Initiatives and infrastructures. But they have risen too high. Stocks of enterprises with reform expectations also present opportunities. Investors should pay close attention to their running status and latest company moves. But you may always be one step behind if you act with public information. Regarding to other conception stocks, they are not bargains, either.

At the moment, it is hard to choose a buy, investors should be careful before venturing your money.
