The so-called "hat-grabbing" transaction refers to securities companies, securities consulting institutions, professional intermediaries and their staff buying and selling or holding relevant securities, and making public evaluation, prediction or investment suggestions on securities or their issuers or listed companies in order to obtain economic benefits through expected market fluctuations. This is a common term.

Related introduction:

Hat grabbing is a kind of speculation in the futures market. In the futures market, speculators buy futures contracts whose prices are expected to rise at a low level on the same day to open positions, and then when the futures price rises to a certain price, they sell the futures contracts they bought on the same day to close positions, so as to obtain the profit of the price difference.

Or, open positions on the same day to sell futures contracts that are expected to fall, and then when futures prices fall to a certain price, buy futures contracts that are sold at low prices and close their positions, so as to obtain the difference profit.

Its origin:

In the early days of securities and futures trading, traders bid in the trading pool and bid by gestures and shouting, so those short-term intraday speculators will keep raising their hands to bid, just like a group of people reaching out to take off their hats (of course, there are no hats in the air), so they call intraday short-term trading "hat grabbing".

The difference with the rat storehouse:

This way is somewhat similar to the "rat barn", but there are differences. Because shareholders can't control the funds of retail investors in the early stage, they have the advantage of controlling the release of information and recommending stocks.
