Generally, I wouldn't advice anyone to invest in stocks. Rather invest in ETFs or even consider letting a professional wealth manager take care of your assets. Hedging risks, diversifying a portfolio properly, reducing volatility and still optimize returns is so difficult a task that if private individuals do it, they could just as well go to gamble.
When you invest, your goal should only be to ditch inflation and keep your assets. If you want to EARN money, better use those assets to start a company yourself - or make portfolio management a full time job, but that will mean that you will have to study a lot of financial theory.
Now for the special case of China:
If you invest in Chinese stocks at the moment, you will most likely lose, despite the fact that China's economy growth. The reason for this is that the government opens the capital market more and more, loosens monopolies and therefore cuts the ability of large Chinese corporations to make profits - which inevitably brings you a negative beta over the long term.
So in conclusion:
It's a bad idea to invest into single stocks as an individual.
And it's a very bad idea to do that in China.
If you gamble on the stock market without doing your research you deserve to loose all you have. Stocks and shares should be invested in for the long term and not for a quick gain. The markets will rise again.
Also if professional stock managers are so good why do they not invest there own money to make a huge profit? Many so called professional have lost a lot of money for their clients but they still get their commission.
My advice is to buy now when the market is at a low.
if you are a personal investor , i suggest you not to invest the stock due to you do not have the completly information a all. in US, 90 percent investor in the stock market are organization investor, however,in china most investor in the stock market are personal investor.
