Risk of Futures and Options Trading

Risk of Futures Trading

While futures trading can make substantial profits, it can also lead to equally significant losses in a short period of time. Futures trading is only for sophisticated and more disciplined investors who can afford potential losses should he find himself on the wrong side of a market.

At the end of each trading day, your position is "marked to market", or valued according to the contract's market value at the end of the day. If the contract price moves against your view so the initial margin deposit falls below the maintenance margin level, we will normally issue a margin call. This means you will have to deposit additional money to restore the initial margin level. If you don't do this, we may liquidate your position at market. You will have to bear any loss arising from the forced liquidation.

Risk of Options Trading

Longing and shorting options are two different strategies. An option holder, who takes the long position, pays a premium to the option's writer. If performance of the underlying asset goes against the holder, his maximum loss will be limited to the premium paid.

An option writer, who takes the short position, receives a premium from the holder. In exchange, he takes up the obligation to settle the contract as specified when the holder exercises the option. If the market goes against the option writer, he may suffer a substantial loss exceeding the premium received.

Remember to evaluate your risk tolerance level before taking up a position.
