Algorithmic trading (algotrading)

Algorithmic trading is a trading system that utilizes advanced and complex mathematical models and formulas to make high-speed decisions and transactions in the financial markets.

American-style option

An option contract that may be exercised at any time on or before the expiration date. For example, if one buys an American call giving him/her the right to buy shares in X expiring on the final Friday in March, the call may be exercised at any time on or before the final Friday in March. The differentiating feature of an American option is the fact that its value varies according to the value of the underlying asset over the life of the contract. This means that a holder may wait for an advantageous price and exercise the option. This contrasts with a European-style option, which may only be exercised on the expiration date.

Asset Allocation

Asset allocation is an investment strategy that aims to balance risk and reward by apportioning a portfolio's assets according to an individual's goals, risk tolerance and investment time frame.

Asset class

At-the-money is a situation where an option's strike price is identical to the price of the underlying security. Both call and put options are simultaneously at the money. For example, if XYZ stock is trading at 75, then the XYZ 75 call option is at the money and so is the XYZ 75 put option.

Balanced Portfolio

A portfolio allocation and management method aimed at balancing risk and return. Such portfolios are generally divided equally between equities and fixed-income securities.

Efficient frontier

The efficient frontier is the set of optimal portfolios that offers the highest expected return for a defined level of risk or the lowest risk for a given level of expected return. Portfolios that lie below the efficient frontier are sub-optimal, because they do not provide enough return for the level of risk.

Exchange-Traded Fund (ETF)

Hedging is analogous to taking out an insurance policy. If you own a home in a flood-prone area, you will want to protect that asset from the risk of flooding – to hedge it, in other words – by taking out flood insurance. Normally, a hedge consists of taking an offsetting position in a related security in order to reduce the risk of adverse price movements in an asset.

Historic volatility

Historical volatility is a measure of the volatility of the underlying stock or futures contract. It is known volatility, because it is based on actual, recent price changes of the underlying asset. Historical volatility can be thought of as the speed (rate of change) of the underlying stock price.

Modern Portfolio Theory

Modern portfolio theory (MPT), or mean-variance analysis, is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk, defined as variance. Its key insight is that an asset's risk and return should not be assessed by itself, but by how it contributes to a portfolio's overall risk and return.
