The multiplier per point of the Shanghai and Shenzhen 300 index futures contract is 300 yuan. According to yesterday's closing price of Shanghai and Shenzhen 300 Index 1938, the contract value of that day is 1938 ×300 yuan = 58140,000 yuan. According to 8% of the trading margin, the margin for investors' first-hand trading is 58 1.400 yuan× 8% = 4651.200 yuan.

However, futures experts said that the financial threshold in actual operation is higher. According to the regulations of the CSRC, when investors participate in futures trading, futures companies should add a minimum of 3% and a maximum of 4% margin. That is to say, when actually trading stock index futures, the minimum margin threshold should be 8%+3% = 1 1%, so investors should invest at least 5814×11%= 64,000 yuan. If the risk reserve is included, at least 10- 15000 yuan should be prepared for futures speculation.
