Spot Price

What it is:

The spot price is the current market price at which an asset is bought or sold for immediate payment and delivery.  It is differentiated from the forward price or the futures price, which are prices at which an asset can be bought or sold for delivery in the future.

How it works/Example:

On November 29, 2010, the spot price of gold was $1,367.40 per ounce on the New York Commodities Exchange (COMEX).  That was the price at which one ounce of gold could be purchased at that particular moment in time.  The spot price for a bushel of wheat was about $648 on the same day.

On November 29, 2010, the futures price for an ounce of gold to be delivered in December 2011 was $1,373.20.  The futures price for December 2011 delivery of a bushel of wheat was about $764.

Large differences between the spot price and the futures price can exist because the market is always trying to look ahead to predict what prices will be. Futures prices can be either higher or lower than spot prices, depending on the outlook for supply and demand of the asset in the future.

Why it Matters:

The spot price is important in and of itself because it is the price at which buyers and sellers agree to value an asset. But spot price becomes an even more important concept when it's viewed through the eyes of the $3 trillion derivatives market.

Spot prices are continually changing -- they fluctuate according to varying supply and demand. To mitigate the risk of continuously changing prices, investors created derivatives. Derivatives such as forwards, futures and options allow buyers and sellers to "lock in" the price at which they buy or sell an asset in the future. Locking in prices with derivatives is one of the most common ways investors reduce risk.

Best execution refers to the imperative that a broker, market maker, or other agent acting on behalf of an investor is obligated to execute the investor's order in a way that is most advantageous to the investor rather than the agent.
