The main reasons for the risk amplification in the futures market are as follows: ① Compared with spot prices, futures prices fluctuate more frequently; (2) Futures trading has the characteristics of "small and wide" and is highly speculative. Excessive speculative psychology of traders is easy to induce risky behavior and increase the possibility of risk generation; (3) Futures trading is different from general spot trading. Futures trading is a continuous contract trading activity, and the risk is easy to extend, triggering a chain reaction; (4) The futures trading volume is large, the risks are concentrated, and the profit and loss range is large; ⑤ Futures trading is forward-looking, and there are many uncertain factors in the future, so it is difficult to predict. So options a, b, c and d are all correct.
