arbitrage (redirected from arbitrages)

Arbitrage

The simultaneous purchase and selling of an asset in order to profit from a differential in the price. This usually takes place on different exchanges or marketplaces. Also known as a "riskless profit".

Notes:

Here's an example of arbitrage: Say a domestic stock trades also on a foreign exchange in another country, where it hasn't adjusted for the constantly changing exchange rate. A trader purchases the stock where it is undervalued and short sells the stock where it is overvalued, thus profiting from the difference. Arbitrage is recommended for experienced investors only.

Arbitrage

The simultaneous buying and selling of a security at two different prices in two different markets, resulting in profits without risk. Perfectly efficient markets present no arbitrage opportunities. Perfectly efficient markets seldom exist, but, arbitrage opportunities are often precluded because of transactions costs.

arbitrage

The simultaneous purchase and sale of substantially identical assets in order to profit from a price difference between the two assets. As a hypothetical example, if General Electric common stock trades at $45 on the New York Stock Exchange and at $44.50 on the Philadelphia Stock Exchange, an investor could guarantee a profit by purchasing the stock on the Philadelphia Stock Exchange and simultaneously selling the same amount of stock on the NYSE. Of course, the price difference must be sufficiently great to offset commissions. Arbitrage may be employed by using various security combinations including stock and options and convertibles and stock. See also basis trading, risk arbitrage.
