Bosera theme fund is a typical medium and long-term fund, and its operation method is extremely stable, ranking third in the big bull market in 2007, but its performance this year is very mediocre, because it is too stable and its position is obviously lower than other funds, and the fund has always emphasized so-called value investment and is not good at short-term speculation. If your investment time is short, it is not recommended that you buy this fund. If you want to take a fancy to the income after 3-5 years, you can consider it, and you must be able to withstand the loneliness and boss theme.
