(2) The risk is smaller than that of futures.
Futures are relative to spot. They are delivered in different ways. Spot is cash spot, and futures are contract transactions, that is, mutual transfer of contracts. There is a time limit for futures delivery. Before the expiration, it is a contract transaction, but the expiration date is to cash the contract for spot delivery. Therefore, large futures institutions often do both spot and futures, which can be used for hedging and speculation. Ordinary investors often can't deliver in time, so they have to speculate purely, and the speculative value of commodities is often related to factors such as spot trend and duration of commodities.
Futures trading is a kind of contract trading, and you only need to pay the deposit corresponding to the actual price of goods for each transaction. The specific margin ratio is determined by the futures exchange according to market conditions, and the futures company will also make adjustments. Simply put, futures is the artificial advance of future commodity prices, which has two functions, one is hedging, the other is speculation, and the spot is the timely transaction of bulk commodities.
