Market Disequilibrium occurs when market and external forces combine to unbalance a market, creating inefficiency in the market in the process. A disequilibrium produces what’s called a “deadweight loss,” “welfare loss,” “excess burden,” or “allocative inefficiency.” As described by efficient market theory, the price fluctuations we see in market behavior are the market trying to find its truly efficient price and quantity – the theoretical point of equilibrium. Investors attempt to locate it using moving averages and other means of technical analysis. Continue reading...
The concept of an efficient market is more applicable today than it was when it was conceived, a truly efficient market is nearly impossible. The Efficient Market Hypothesis states that random new information will affect the value of securities, and that new information disseminates so quickly among rational investors that it is futile to try to beat the “market portfolio.” Thirty years ago, this was more of a theory than an observable phenomenon, and plenty of inefficiencies in the dissemination of information and the pricing of securities could be pointed out. Continue reading...
Market efficiency describes the degree to which relevant information is integrated into the price of a security. With the prevalence of information technology today, markets are considered highly efficient; most investors have access to the same information with prices and industry news, updated instantaneously. The Efficient Market Hypothesis stems from this idea. Efficient markets are said to have all relevant information priced-in to the securities almost immediately. High trading volume also makes a market more efficient, as there is a high degree of liquidity for buyers and sellers, and the spread between bid and ask prices narrows. Continue reading...
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...
The Efficient Market Hypothesis (EMH) states that it is impossible to beat the market consistently over time, since all available information is priced efficiently into stock prices. But what the EMH misses is the impact that sentiment can have on price discrepancies in the short-term. Emotions can lead to gross mis-valuations (as we saw with the tech bubble in 2000), and market corrections can see stocks selling off dramatically for no fundamental reason. 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...
The Elliot Wave theory essentially uncovers larger trends and investor sentiment by smoothing and “zooming out” from market price action. Elliot Waves zoom out on market price action by using larger-interval moving average and smoothing out price information to reveal larger trends. He was one of the first to attempt such a theory, and his foundations may have contributed to the use of Fourier Analysis and Fibonacci Sequences in market analysis. 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...
The Black Swan Theory serves as a reminder to investors that unpredictable events can radically change our lives, society, and the markets. The Black Swan Theory, based on a recent book by Nicholas Nassim Taleb called “The Black Swan: The Impact of the Highly Improbable,” analyzes how events that were completely unexpected, or perhaps considered impossible, radically changed the world. Historical events such as the attacks of September 11th, 2001 and the invention of the personal computer are categorized as Black Swans: they were unforeseeable, and their enormous impact on human civilization was only explainable in hindsight, according to Dr. Taleb himself. Continue reading...
The momentum theory has many fans for its useful and relatively simple nature. The momentum theory basically states that markets which are moving either up or down for some period of time cannot suddenly reverse their course. Utilizing these strategies means jumping on a freight train, riding it for a short period of time, and jumping off before it stops and reverses direction. It is hard to argue with the this one, but it may be hard to find momentum strong enough for an investor’s taste in certain market environments, which might mean spending too much time on the sidelines, and due to the frequent active trading involved, the investor will incur fees and be susceptible to emotions and media hype. Continue reading...
The Random Walk Hypothesis states that in an efficient market, prices will correlate around the intrinsic value of securities, but there will always be a randomization and unpredictability to it. The Random Walk Hypothesis suggests that technical analysis and the efforts of chartists cannot beat the market over time, because the market will move randomly and unpredictably, and past results cannot predict future returns. Continue reading...
Dow Theory is perhaps the longest-standing method of market analysis still used in modern finance. It suggests that markets experience primary trends (which last several years), intermediate trends (which last under a year), and minor trends (which last less than a month). Markets are in an upward trend if an average exceeds certain thresholds, followed by a similar movement from another average. Longer, larger trends are considered more predictive than smaller ones, though correctly reading the primary trend in the main goal. Continue reading...
Simply put, insider trading is the crime of trading in a company’s stock based on information not available to the general public. According to the efficient market theory, any publicly available information is immediately "priced-in" to a stock, so any article you might find in a news publication is not going to give you a competitive advantage for a stock's future price movements. Insider trading tips give an unfair advantage to the holder of the information, since the market has not had a chance to react to it yet. Of course, insider trading is illegal and several notorious cases have been well-publicized, like that of Martha Stewart. She was jailed. Continue reading...
There are investments which have the potential for very high returns, but they will always be that much riskier than the lower-yielding alternatives, and this is part of the risk/return trade-off. The relationship between risk and return is a positive linear relationship in most theoretical depictions, and if an investor seeks greater returns, he or she will have to take on greater risk. This is called the risk/return trade-off. For more stability and less risk, an investor will have to sacrifice some potential returns. Continue reading...
The Home Market Effect is a term used in macroeconomic theory describing a concentration of an industry’s production facilities being concentrated in the larger national economies where its primary consumers exist. The home market effect (HME) is a theoretical term used in trade theory economics. The domestic economy in this case has an effect on the international prices and economy related to these goods. Continue reading...
It requires a great deal of due diligence, but investors should understand that past performance is not indicative of future performance. Focus on experience. In the stock market, as with most things in life, hindsight is 20/20. There are countless lists on the internet with titles like “The Best Mutual Fund Families” and “50 Winning Mutual Funds.” It is important to understand that the names on those lists are a function of hindsight and not foresight. Continue reading...
The Dow Theory may not always be accurate, but it has been part of the foundation of modern market analysis. The Dow Theory was formulated by the famous economist Charles Dow. What is important is that the Dow Theory concerns itself with the movements of very broad markets, rather than individual stocks. In particular, the Dow Theory, which was named post-mortem and summarized the editorials Dow wrote during his life, focuses on the movement of the Industrials (DJIA) relative to the Transportation index (DJTA) and theorizes that if one moves the other should follow, and if there is discord a reversal is probably coming. Continue reading...
The debate on whether active or passive management is better for investors has polarized many advisors and theorists for years. There are two schools of thought when it comes to long-term investing. One basically states that you should determine a proper allocation of asset classes for yourself, buy index funds to reflect each particular asset class, and possibly rebalance the portfolio periodically. This basically means “set it and forget it,” and the investor must be willing to ignore fluctuations in the markets and maintain a faith in an Efficient Market. Continue reading...
Market Equilibrium occurs when fluctuations between supply and demand balance out, keeping prices relatively stable. This trend appears relatively horizontal or sideways when charted. Both price equilibrium and quantity equilibrium should meet at the same point where the supply and demand curves meet on a chart. According to the Law of Supply, with all factors being equal, if the price of a good or service increases, the supply of that good or service will increase. If demand doesn't meet it, the price of that good or service must come down; this increases demand but might cause a shortage in supply, which might drive prices back up, and so on. Continue reading...
The “Efficient Frontier” is a modern portfolio theory tool, which demonstrates to investors the best possible returns they can expect from their portfolios, relative to the amount of risk they’re willing to accept. For investors that find themselves below the “Efficient Frontier,” it means their strategy is not providing enough return for the level of risk assumed. The opposite is true as well. What the theory means to communicate is that investors would be wise to include some higher growth, higher risk securities in their portfolios, but combine them in a strategic way so as to gain risk/reward value that comes with diversification. Continue reading...
