In the last two years, Bosera Fund has been in a downturn as a whole, with poor performance. If you must buy it, only the Bosera theme is ok. It was once a star fund in the big bull market in 2007, but its performance was at the bottom last year. This year, it seems to have regained its vitality. The fund belongs to the medium and long-term fund and is not good at short-term speculation. Other suggestions are to consider Harvest and Guo Fu series funds, both of which are good, and the company size is also the top ten companies.
