There is no such thing as bad luck in the markets. Understand that every time you put money in the market, you are gambling to some extent against professionals. Today, the famous web company called LinkedIn gets crushed even though they are a decently growing TMT company. This is why professionals don’t make big bets before earnings releases. Don’t think this can’t happen to Baidu, Alibaba or even Tencent… Casual investors always lose in the long run.
