Yes, margin trading as it applies to futures trading and stock trading are two different things and carry important distinctions that a trader should understand before engaging in futures trading.
Typically, stocks that are available to be traded on margin require at least 50% of the purchase price in order to trade. Stock traders pay interest on the margin they use, since the margin is extended as a loan, adding to the cost of doing business for the trader. Not all stocks are available to be traded on margin and those that do not qualify require full funding of the securities value in order to trade.
Margin in futures trading is a performance bond that a trader uses to ensure the performance of the contract terms. Since it is not a loan, there is no interest to pay and the margin requirements in futures typically allow for much greater leverage than stocks, which also increases the risks associated with futures trading. All futures contracts are offered based on margin as a performance bond, so there is no applicability with certain listings not being available for margin trading, as can be the case with certain stocks.
