Stock index futures are a little different from stocks, and everything else is the same:

1, stock index futures can rise (long), can fall (short), and stocks can only rise;

2, the introduction of the stock, a few thousand pieces can be, the stock index needs 500 thousand.

3. All stocks are traded, with the stock index about 15% and the fund 100% contract. Leveraged trading.

That's all.

If you use 500,000 yuan as stock index futures, it is actually risky to trade 100% of the stock with the contract value of 50 yuan (the remaining funds are lying in the account). Doing stock index futures has also become an index fund.
