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...
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...
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...
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...
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 “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...
A market maker is a broker-dealer firm or a registered individual that will hold a certain number of shares of a security in order to facilitate trading. There could be as many as 50 market makers for one particular security, and they compete for customer order flows by displaying buy and sell quotations for a guaranteed number of shares. The market maker spread refers to the difference between the amount a market maker is willing to pay for a security and the amount that the other party is willing to sell it. Continue reading...
Earnings surprises occur when the reported quarterly or annual earnings of a company are different than they were projected to be. This could be a good surprise or a bad surprise. The price of a stock will change quickly with this new information. Positive or negative earnings surprises occur when the earnings estimates for a company in a given quarter or year turn out to be better or worse than expected. Positive surprises will naturally cause the stock price to jump up, while negative surprises will cause the price to fall. 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...
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 efficiency ratio is a metric that measures how effectively a company uses its assets and liabilities to run the business smoothly. There are several types of efficiency ratios that can give an analyst insight into a company: accounts receivable turnover, fixed asset turnover, sales to inventory, and and stock turnover ratio. 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 difference between the Bid and Ask prices on a stock or other security are known as the Spread. Designated market makers are traders whose job it is to make a market for securities, by offering to buy or sell shares, and thus creating liquidity, often at the same time. Their money is made on the spread. In highly liquid markets, the spread will shrink. So if everyone is buying and selling the same stock one day, there may be virtually no spread between the Bid and the Ask price, and this is seen as efficient. Continue reading...
The Adaptive Market Hypothesis uses theories of behavioral economics to update the aging Efficient Market Hypothesis. There have been many debates surrounding the Efficient Market Hypothesis and its validity, and a lot of research over the last 15 years or so has been done which suggests that behavioral finance holds many of the keys to an accurate “universal theory” of the markets. A marriage between the two schools of thought has given birth to the Adaptive Market Hypothesis, coined in 2004 by Andrew Lo of MIT. Behavioral and evolutionary principals come into play when theorizing about the large-scale behavior and adaptation of humans in a system. Continue reading...
The October Effect, also known as the Mark Twain Effect, is an anecdotally-founded fear that markets are vulnerable to catastrophe in the month of October. Several Octobers have appeared to be the origin of problems in the market: in 1929 at the onset of the Great Depression, the 1987 crash, and in 2008 at the start of the Great Recession. Perhaps superstitiously, many people expect October to be the worse month of the year for the market, supposing that if something bad were going to happen, it would happen in October. Statistically, there isn't much support for this idea. 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...
Mark to Market (MTM) is an accounting method meant to price an asset by its most recent market price. An example would be mutual funds, whose “NAV” price is a mark to market price of how much the mutual fund closed for at the end of a trading session. The mark to market accounting method has some pros and cons. On the pro side, if an asset is very liquid, then MTM will provide an accurate reflection of its current value. Continue reading...
A business with a fast ‘cash conversion cycle’ can efficiently use funds and resources to fulfill the different needs of the business and to generate more business. In the simplest terms, the ‘cash conversion cycle’ is an accounting and efficiency model which measures how fast a retailer can disburse cash to suppliers and then receive cash from customers. To be more descriptive, the business would use cash from Receivables, to get Inventory (and cover Payables), sell that Inventory, and Receive cash again. Continue reading...
Turnover ratio is a term that can be used in reference to the rate at which a company goes through its physical inventory, or that a mutual fund sells and replaces its investment holdings. In the context of a company’s inventory of goods, a high turnover ratio is a positive sign. It means that a company is selling plenty of its products and is not wasting money on more warehousing space than it needs. This kind of turnover ratio is calculated as the cost of goods sold in a period divided by the average inventory during that time. In the context of mutual funds and ETFs, turnover ratio is a negative thing if it is high. 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...
