Where did short stocks come from?
Short-selling stocks come from brokers, including their own stocks and stocks integrated through refinancing business. The way of A-share short selling is called short selling, and the process of short selling is from "borrowing securities to selling" to "buying securities to returning them". In this process, if the stock price falls, investors can make a profit, and brokers have to charge interest fees to investors.
Refinancing business: refers to the provision of funds and securities by banks, funds, insurance companies and other institutions, and securities companies as intermediaries provide these funds and securities to margin customers.
Short selling is just one of the ways to short. Besides short selling, short selling also includes stock index futures and stock index options. Shorting stock index futures and stock index options needs to bear high fluctuations, but the advantage is that there is no interest expense and the trading system of T+0 is implemented.
