Plenty of theories are known because they are useful, and it is up to you to discern which ones may be worth your time and fit your situation and investment or analysis style. There’s always merit to any theory which has been put through rigorous statistical tests. However, keep in mind that as with any other statistical inferences, an event with probability zero sometimes happens (Black Swans), and an event with probability one sometimes doesn’t.

Analytical financial theories and trading strategies can be “backtested” by applying them to historical data. Backtesting is to simulate what it would have been like to use a certain strategy or indicator in the past. Because markets are more complicated than a simple algorithm, such as an assumed future rate of return, it is preferable and somewhat more dramatic to use actual historical data for testing. There is an abundance of historical market data available to those who would like to use it for backtesting a theory, strategy, or indicator. Continue reading...
Market research is the process of evaluating a possible opportunity for entering into a market with a new product or company, or for evaluating the effectiveness of a product or company in a market that they are already invested in. Market research can also be important for decisions regarding mergers and acquisitions. It may involve surveys and market study groups. Sometimes a company will conduct its own market research, but often third-party companies are hired for the task. These companies may specialize in sampling and surveying methods for consumer groups, and/or statistical analysis of a business model or product’s chance of success in a given market. Companies may look to such analysts if they are considering a merger or acquisition, or of launching a new product. Continue reading...
In statistics, the number of times that a specific value shows up in a data set is the absolute frequency of that value. The absolute frequency can then be used to find the relative frequency, which is the probability that the specific value is observed in a given number of trials. The relative frequency (empirical probability) takes the absolute frequency and divides it by the total number of trials (cumulative frequency), and can be expressed as a ratio or percentage. Continue reading...
Based purely on statistics, the “best” performing stock ever between 1957 and 2007 was Phillip Morris (cigarette maker). If you had invested $1,000 into the company in 1957, your investment would be worth a little under $6 million today. Of course, during those 50 years, you would have had to survive the sudden dips and jumps involved without making any rash decisions, something very few investors have the stomach for. Continue reading...
R-squared is a statistical tool called a correlation coefficient. It is a percentage measurement that represents how closely correlated a security’s movement is with the movements of a benchmark index. Values range between 0 and 1 and are often expressed as percentages between 0% and 100%. A higher R-squared (between 85% and 100%) tells investors that a security moves more or less in correlation with the benchmark index. A lower R-squared (70% or less) means that the security in question moves independently from the index. Continue reading...
Trend analysis is an attempt to explain market movements as general directional tendencies of various strength over various time frames. Trend analysis also works to predict future movements based on the probability of a trend continuing. The use of moving averages with support and resistance levels is the most commonly used methodology in trend analysis, and several trading strategies employ these tools in various ways. Trade volume, spreads, news, crossover points, and other market factors are also considered in the discipline. Continue reading...
The attempt to represent events and phenomena mathematically and to thereby make reality more understandable is called quantitative analysis. To quantify something from the real world, an analyst will translate the factors and variables present in a real event into a coding system which will allow it to be represented in mathematical or computational symbology. The quantitative analysis that follows will attempt to create formulas and test them for external validity and replicability. Continue reading...
The analysis of convergence and divergence between indexes and other data seeks to find leading indicators where there is confirmation or non-confirmation of trends. Dow Theory was one of the first examples of such thinking. Charles Dow would watch the movements of Industrials and the Rail and compare the uptrend or downtrend of each. Where trends do not line up (e.g., one is trending downward with lower troughs and the other has “higher lows”) there is “divergence”, and non-confirmation of what was thought to be a trend in one index. Continue reading...
Fourier Analysis is a mathematical method of identifying and describing harmonic patterns in complex oscillating environments, and is used in options pricing among other things. Fourier Analysis is used to compute the probability that results will be within a certain range. Fourier analysis also has many other applications in physics, engineering, and music, for instance, because it can create a system for identifying patterns and simplifying computations for complex systems which feature oscillations and waves which have frequencies. Continue reading...
Investment analysis is the practice of evaluating assets or securities in terms of value, risk and return, as well as correlation with other assets. It is to determine their possible place within various strategies and portfolios. Some analysis will be done seeking the best option for specific asset classes, some analysis will focus on the best overall portfolio for a given situation. Analysis is done using quantitative metrics and indicators, some of which can be considered fundamental analysis tools and some of which are technical analysis tools. Continue reading...
Fluctuations are represented in terms of volatility, and different types of investments experience different levels of volatility. The answer here depends on which market you’re talking about. Generally speaking, the capital markets in fixed instruments, such as government bonds, are the least volatile. Market fluctuations of the price of commodities, small-cap stocks, and emerging markets are the largest, and can be as high as 30-40% per year. Continue reading...
Technical analysis is a method of evaluating the worth and probable future direction of security prices using charts and data concerning prices and volume. This is the counterpart to fundamental analysis, which looks at the physical operations of a company and their place in the market to determine value. Those who practice technical analysis are sometimes called “quants” or chartists because they believe that the most important information about a security will be found in the data on the price, volume, and the moving averages and volatility associated with them. Continue reading...
What does it mean to technically analyze a stock or other security? Technical analysis involves identifying price ranges, trend momentum, and points of possible reversals via graphical representations of the math behind price movements, examining information to the second or third derivative, and using trial-and-error with formulas. Geometry, calculus, physics, and finance all play a part in this methodology. Continue reading...
Securities in the market can be analyzed on technical levels or fundamental ones, and it is generally best to take both into account, despite the fact that some theories dispute the merits of technical analysis. Some might say that fundamental analysis is all that you need to make wise investment decisions, and to some extent that is actually correct: at a minimal level, if all you had were fundamentals, you could make wise investment decisions. That does not mean, however, that all technical analysis is superfluous. Continue reading...
Fundamental analysis has been around for a long time, and will probably always remain relevant. Fundamental Analysis is the oldest and most well-established market theory. Fundamental analysis is to take all the real-world information about a company into account when evaluating securities and to acknowledge that the shares are what they are: partial ownership in a company. It follows that someone should know about the company and its earnings potential. Continue reading...
There are a few ways to measure unemployment, but it is normally interpreted as a percentage of the working-age population that does not have a job. The statistics that are used to determine unemployment rate typically use the number of unemployed people who are actively searching for a job. The Bureau of Labor Statistics conducts a monthly poll called the Current Population Survey which goes out to about 50,000 households, and this is a significant source of unemployment data. Continue reading...
The Consumer Price Index (CPI) is calculated using prices of sample goods from predetermined urban areas. According to the Bureau of Labor Statistics (BLS), the CPI is a product of a series of interrelated samples. First, using data from the 1990 Census of Population, BLS selected the urban areas from which data on prices were collected and chose the housing units within each area that were eligible for use in the shelter component of the CPI. The Census of Population also provided data on the number of consumers represented by each area selected as a CPI price collection area. Continue reading...
Your risk tolerance should be a measure of how willing you are to absorb losses in your portfolio. Studies in behavioral science show that investors loathe losses about two and a half times more then they enjoy gains. Everyone can likely relate to this stat. But, to be a successful investor that achieves long-term equity like returns, one has accept some level of risk inherent in the stock market. Continue reading...
Mortgage fallout refers to the instance of proposed loans falling through before closing. This is something tracked by not only mortgage producers and their mortgage companies, but also economists who keep up with mortgages and the secondary market for mortgage derivatives. Since mortgages take two months or more to close, the fallout rate can indicate a stagnancy in the economy and trouble for the secondary mortgage market. Continue reading...
