What is Margin call, Leverage and Profit & Loss

Margin Call

When the margin posted in the margin account is below the minimum margin requirement, the broker or exchange issues a margin call. The investors now either have to increase the margin that they have deposited or close out their position. They can do this by selling the securities, options or futures if they are long and by buying them back if they are short. But if they do none of these, then the broker can sell their securities to meet the margin call. If a margin call occurs unexpectedly, it can cause a domino effect of selling which will lead to other margin calls and so forth... Effectively crashing an asset class or group of asset classes.



This situation most frequently happens as a result of an adverse change in the market value of the leveraged asset or contract. It could also happen when the margin requirement is raised, either due to increased volatility or due to legislation. In extreme cases, certain securities may cease to qualify for margin trading; in such a case, the brokerage will require the trader to either fully fund their position, or to liquidate it.

A broker's demand on an investor using margin to deposit additional money or securities so that the margin account is brought up to the minimum maintenance margin. Margin calls occur when a you account value depresses to a value calculated by the broker's particular formula.

Leverages

Leverage can be created through options, futures, margin and other financial instruments. For example, say you have $1,000 to invest. This amount could be invested in 10 shares of Microsoft stock, but to increase leverage, you could invest the $1,000 in five options contracts. You would then control 500 shares instead of just 10.

Leverage of 1:100 meaning you pay $1 and get $100 worth of value on currency paper.

Profit and Loss

A financial statement that summarizes the revenues, costs and expenses incurred during a specific period of time - usually a fiscal quarter or year. These records provide information that shows the ability of a company to generate profit by increasing revenue and reducing costs. The P&L statement is also known as a "statement of profit and loss", an "income statement" or an "income and expense statement".
