Group 1 - The core difference between stock trading and futures trading lies in the underlying assets, with stocks representing equity in publicly listed companies and futures being standardized contracts for future delivery of goods or financial assets [1] - Stock trading typically follows a T+1 settlement system, while futures trading employs a T+0 mechanism, allowing for multiple transactions within the same trading day [1][2] - Futures trading supports both long and short positions, enabling investors to profit from both rising and falling prices, whereas stock trading primarily allows for profit through long positions [1][2] Group 2 - Leverage is a key distinction, with stock trading requiring full payment of the stock's value, while futures trading allows participation with a margin of 5%-20%, amplifying both potential returns and risks [2] - The sources of returns differ, with stocks generating income from capital gains and dividends, while futures profits are solely derived from price changes, with higher risk due to leverage [2] - Futures trading involves daily settlement of accounts, ensuring margin requirements are met, unlike stock trading which does not have mandatory daily settlements [2] Group 3 - The trading purposes for stock investors typically include long-term holding for value appreciation and short-term speculation, while futures participants also include hedgers who use contracts to lock in prices and mitigate risks [3]
