1. Price discovery: The future egg price can be reflected through the egg futures market. Both buyers and sellers can quote through the futures market and finally win the recognized price. For example, in the next three months, 50 people will buy eggs for 4.2 yuan, 4.4 people will buy them for 100, and 4.5 people will buy them for 10. Some people sell it at 4.2, 60 at 4.4 and 30 at 4.5. From the quotation, we know that 4.4 yuan is the price recognized by most people. Everyone is willing to buy and sell eggs in 4.4 yuan in the future. Therefore, a bull market or a bear market can raise or lower the future market price through futures.

2. Hedging: As a person who needs to buy and sell eggs in the future, in the face of uncertain market and rising, the buyer has to pay more costs; Falling, people who sell eggs will have less income in the future. Therefore, only hedging is the most effective: in the futures market, buyers are long and sellers are short. Even if the eggs go up or down in the future, both buyers and sellers can lock in the cost price to avoid big losses.
