The discipline of mathematical statistics and the measure of volatility of investments are example concepts that have a tendency to scare the average investor. The standard deviation based on the rate of return of an investment is a measure of the volatility of the investment and is a good representation of risk found in stocks and options. It is said in Wikipedia that Karl Pearson, Fellow of the Royal Society, established the discipline of mathematical statistics. Karl Pearson first used the term "Standard Deviation" in writing in 1894 subsequent its use in his lectures. Standard Deviation is considered vital when used for financial issues.
Thus, large standard deviations indicate that the data points are considerably from the mean and a modest standard deviation indicates that the data points are clustered a lot nearer to the mean. When looking at your investments, standard deviation serves as a measure of uncertainty. It is believed that standard deviation of a group of repeated measurements should give the precision of individual measurements.
When deciding whether measurements agree with a theoretical prediction the standard deviation of those measurements is of critical importance. There is practical value to be gained when online investing by understanding the standard deviation of a set of values and in appreciating how much variation there is from the average (mean) of stocks, options or the market indices.
Great representations of the extreme risks associated with an offered security such as a stock, option or even a portfolio of securities are given by standard deviation. Proper management of an investment portfolio requires a great understanding of the risks inherent with those portfolios. As a determining factor, risk affects the variations on the returns of the portfolio and gives investors a mathematical foundation for investment choices regarded as mean-variance optimization. Just as risk will increase, the expected return on your portfolio will improve and the unknowns of the return will also boost. Standard Deviation provides a quantified estimate of the uncertainty involved with return on investments.
Investors need to place a great deal of importance on using standard deviation when we make trading decisions. When online investing with options it is even more paramount that the investor understands and is able to make proper use of tools such as standard deviation and Bollinger Bands. This is especially true since options involve risks that are not suitable to all investors.
Investors looking to write covered calls are best supported by stocks with a reduced standard deviation in their historical past. In a different approach, when they are seeking to write puts then it is a good idea to look for a stock with a high standard deviation. When there are large variances in standard deviation, the security will have higher risk and variance. Analysis tools called "Bollinger Bands", which are used by technical analyst, was originally created by John Bollinger to determine the highness and lowness of cost relative to earlier trades.
Bollinger Bands consist of a middle band being an N-period (usually the simple moving average), an upper band at K times an N-period standard deviation above the middle band, and a lower band at K times an N-period standard deviation below the middle band, where N and K are usually 20 and 2 respectively.The use of these Bollinger Bands are very helpful in recognizing patterns and comparing price actions of stocks and therefore are very useful for making systematic trading decisions. When used with other tools and data, Bollinger Bands are a very effective management tool that has a practical use of standard deviation and its use in making decisions for your online investing.
For most typical situations, standard deviation is a very good concept and one that all traders should recognize. Therefore, online investing for beginners really should start with finding a full understanding of these and other investment phrases.
