Convertible bonds can be bought. Convertible bond is a financial instrument with bond characteristics and stock options. Its price will be affected by the relationship between supply and demand, changes in interest rates, company fundamentals and other factors, with ups and downs. In the securities market, investors can choose to buy or sell convertible bonds at an appropriate time according to their own judgments and strategies. If you think the price of convertible bonds will fall, you can choose to buy at a low price or sell short (by borrowing convertible bonds and buying them back later) to earn the difference.
