Try to give a simple and rough explanation as follows. (Non-professional opinion, or biased):

call wheel is a subscription card; Put round is a put certificate.

If you are bullish on HSBC and the stock price is now 6 yuan, you think it will rise to 1 yuan in the next year, but you don't want to buy it with too much cash and want to earn more profits than buying stocks. Therefore, you may have taken a fancy to a call round of HSBC due next year and bought this call round. Theoretically, you are allowed to buy it on a certain due date next year. The right to buy shares in HSBC at a "flat" price (for example, 55 yuan). If HSBC has been strong and steadily rising since then, your call round will appreciate more and more, because it seems that you can buy shares in HSBC at a flat price one year later. The increase can be very amazing.

As for the put round, it is the opposite of the call round. That is to say, there are many varieties of "buy down". call/put round, and the calculation method is extremely complicated, which is beyond the understanding of ordinary investors. However, the mentality of "gambling" always only cares about the opportunity to make big profits, and people will buy it if they don't know.

Bull/bear certificates and call/put round have a time limit, and investors can hold them until the maturity date or sell them before the maturity date.

However, That is, it must be recovered before the maturity date. For example, when X shares rise to a certain level, their related bull certificates will also rise, and when they reach a certain level, investors can make profits. On the other hand, if they fall and touch a certain level, they will immediately "die" and investors will have to pay the bill. On the surface, it is very corrosive, as if there is no revenge, but the advantage is that investors have a budget and know that there is a certain upper and lower limit to make profits or lose money. Moreover, Although you can wait until the expiration date of the last day, don't forget that there are different stocks, and you need to calculate the time value and premium loss. Therefore, usually, after the stocks plummet, they will rise to a similar level in the future, but the related stocks cannot rise at the same rate. < P > Supplement: < P > For the bull-bear certificate, please refer again: < P > op=ViewArticle& articleId=1462
