Stock repurchase refers to the behavior of a listed company to buy back a certain number of shares issued by the company from the stock market in cash. After the stock repurchase is completed, the company may cancel the repurchased shares. However, in most cases, the company reserves the repurchased shares as "treasury shares", which no longer belong to the issued shares and does not participate in the calculation and distribution of earnings per share. Treasury shares can be used for other purposes in the future, such as issuing convertible bonds and employee welfare plans. Or sell them when you need money.

Overweight: a jargon in the securities industry, as the name implies, is overweight, which can also be called jiacang. Whether buying stocks, futures, funds or other securities and commodities that can be listed and traded on the original basis, it can be called increasing holdings. In other words, you have a certain position, and buying more means increasing your holdings-adding positions.
