Some of the securities include stocks and bonds, raw materials and precious metals, which are known in the financial markets as commodities.

Financial markets attract funds from investors and channels them to corporations—they thus allow corporations to finance their operations and achieve growth.
The following table illustrates where financial markets fit in the relationship between lenders and borrowers: The lender temporarily gives money to somebody else, on the condition of getting back the principal amount together with some interest or profit or charge.
When companies have surplus cash that is not needed for a short period of time, they may seek to make money from their cash surplus by lending it via short term markets called money markets.

Large amounts of volatility often indicate the presence of strong emotional factors playing into the price.
In recent years the rise of algorithmic and high-frequency program trading has seen the adoption of momentum, ultra-short term moving average and other similar strategies which are based on technical as opposed to fundamental or theoretical concepts of market behaviour.
For instance, according to a study published by the European Central Bank,[9] high frequency trading has a substantial correlation with news announcements and other relevant public information that are able to create wide price movements (e.g., interest rates decisions, trade of balances etc.)
The scale of change, or volatility, depends on the length of the time unit to a power a bit more than 1/2.
