RPA2 Module 6 Flashcards
Enumerate the propositions on which the behavioral finance view of markets and market efficiency is based.
(a) Informed traders face risk-aversion constraints in seeking to keep prices
efficient. The efficient market hypothesis (EMH) argues that well-informed, risktolerant investors keep prices at their “fair values.” When prices are sufficiently out of line to warrant action by investors, they act to move them back. However, there are limits to arbitrage, which may constrain price adjustments.
(b) The trading decisions of individual investors are biased because of biases associated with human behavior.
(c) The purchases and sales of individual investors are highly correlated. In other words, individual investors tend to buy and sell the same stocks at the same time. This herding effect by individual investors can push the prices of stocks in one direction in a significant manner.
(d) Individual investors, who are considered the uninformed investors, generate buy/sell imbalances that drive prices away from fundamental value.
(e) Over time, informed investors will drive prices back to fundamental value.
Explain the contribution to the theory of behavioral finance by DeBondt and Thaler known as the overreaction hypothesis.
People overreact to unexpected and dramatic news events. As applied to stock prices, the hypothesis states that, as a result of overreactions, “loser” portfolios outperform the market after their formation. The researchers interpreted this evidence as indicative of irrational behavior by investors, or overreaction. Investors overreact to information about companies and drive stock prices to unsustainable highs or lows. When investors realize later that they overreacted to the news, prices return to their correct levels.
Does behavioral finance say or imply that people can beat the market because of irrationality and behavioral biases?
No. Because of the irrationality and behavioral biases of other investors.
Such a claim is an often-made basic misunderstanding of behavioral finance. What behavioral finance says is that market prices and fundamental values can diverge because of psychology. Opportunities may be present as a result of this divergence; however, investment managers will not necessarily try to exploit the opportunities.
Why? Informed investors may not be willing to take the risk involved to try to
exploit these opportunities, or constraints exist that prevent them from doing so.
What is contrarian investing?
The belief or investment theory that holds it is profitable to trade contrary to most investors.
This investment approach involves taking positions that are currently out of favor. The investing philosophy particularly espouses the investor overreaction hypothesis, which states that investors overreact to events in a predictable manner, overvaluing the best alternatives and undervaluing the worst. Those who practice the contrarian investing approach tend to favor low price/earnings (P/E) ratio stocks, which are often out of favor, rather than the often popular high P/E ratio stocks.
What does the performance of professional investors seem to indicate regarding the efficacy of market efficiency?
That markets generally tend to be highly efficient.
When looking at data on the performance of mutual fund portfolio managers, the following statistics on performance should be noted:
(a) Approximately 70% of mutual fund managers underperform over a ten-year period, and 80% underperform over a 20-year period.
(b) Over a recent five-year period, only 6% of U.S. stock funds achieved a ranking in the top half for five consecutive 12-month periods.
(c) Over a period of 30+ years, of the 139 mutual funds in existence for the entire period, only 20 funds outperformed by two percentage points or more.
(d) Consider the consistency of performance of mutual funds over a recent ten-year period. Take the top 25% of large capitalization funds during the period 2001-2006. Over the subsequent five years, 2007-2011, only 12% of the earlier top performers were in the top 25%.
(e) As for institutional portfolios, research shows that after adjusting for risk, well under 1% achieve superior results after all adjustment for costs.
Summarize some of the contrary evidence that researchers have found regarding market efficiency.
Some anomalies exist and may offer opportunities to astute investors.
Another example of contrary evidence involves the crash in stock prices that occurred in October of 1987. The Standard & Poor’s (S&P) 500 index lost over 20% of its value in a single day. With this occurrence, the question is posed as to whether it is reasonable to argue that investors, efficiently discounting information, decided in one day that the market should be valued at a level that was 20% below the prior day’s level.
Yet a third example of market inefficiency involves the Internet market bubble that burst in 2000. After climbing to exorbitant heights in 2000, the market significantly declined in value during the two subsequent years.
Given the controversy involving market efficiency and research findings from
behavioral finance, what choice is left to investors?
Pursue an active investment strategy, a passive investment strategy or some combination thereof.
Making the choice depends heavily upon what the investor believes about
efficient markets. However, investors who plan, or wish, to pursue some type of active strategy should consider a quote attributed to Warren Buffett:
“Most investors, both institutional and individual, will find that the best way to
own common stocks (shares) is through an index fund that charges minimal
fees. Those following this path are sure to beat the net results (after fees and
expenses) of the great majority of investment professionals.
How do the studies of behavioral finance and behavioral economics have
relevance to retirement plan design as the private retirement system places greater emphasis on defined contribution structures?
Behavioral finance and behavioral economics are fields of study that apply the use of scientific research techniques to understand social, cognitive and emotional biases that affect and influence economic decision making.
These fields of study concentrate on the decisions of individual and collective economic agents and study whether the decisions they make are entirely rational or seem to lack rationality.
Since the trend in retirement plan design has shifted to a defined contribution model where individual plan participants are largely responsible for making investment decisions and bearing the risk associated with those decisions, the field of behavioral finance is highly relevant to plan sponsors to understand the biases that may either help or hinder the decision making that will contribute to plan participant long-term economic security.
As researchers have studied decision making in the newly emerging field of
behavioral finance, what are certain key themes that have been found within these studies?
HFM
(a) Heuristics: People often make decisions based on approximate, so-called rules of thumb that are not entirely grounded in strictly rational analyses. Shortcuts to decision making can result from difficulty in assembling all of the relevant information or from limitations on the decision maker’s capabilities or competencies. Therefore, decisions often fall short of the optimal positive determinations suggested by neoclassical economists.
(b) Framing: The way a problem or decision is presented will affect an individual’s action. The outcome then is sometimes less than optimal. Importantly, decision makers are influenced by the depiction of the choice, and their decisions appear to be susceptible to manipulation. This theme has both negative and positive implications. On the negative side, it suggests that economic agents’ decisions can be flawed and are far less reliable and logical than previously envisioned. On the positive side, however, is the potential promise that decisions framed differently can guide decision makers to make more optimal choices.
(c) Market inefficiencies: Market outcomes diverge from what would be expected if market efficiency was present. Real-life outcomes that previously appeared unexplainable by economic modeling are seen as explainable once social, cognitive and emotional biases are recognized. No longer must observable conditions in the real world be deemed unexplainable or mysteriously incongruent with logical economic modeling. The introduction of a more accurate portrayal of human economic agents explains market conditions
What are some of the implications of the key themes enumerated in the previous question, particularly as they relate to retirement plan design?
individuals make decisions with incomplete information, are likely to be influenced by the way the decision is presented and make suboptimal choices as a result.
Although this model is one of suboptimal choice and inefficiency, it allows for the facilitation of better decision making by framing the decisions differently.
The application of behavioral finance is very appropriate in the context of selfdirected, defined contribution plan management. With these types of plans, individual participants are faced with the opportunity to make decisions that will enhance their long-term financial security. Essentially, the worker must choose to participate, to set a contribution rate, to select various investments and ultimately to decide how funds are withdrawn from the account. All of these decisions are complex determinations. With the shift from defined benefit plans to defined contribution approaches and, with the elements of defined contribution plan design that place many responsibilities for decision making on the individual participant, the study of behavioral finance and behavioral economics is very relevant to the
study and design of retirement plans.
Discuss the findings of behaviorists on individual investment decision making,
specifically noting the two major categories of impediments that impede rational decision making in this area.
Some of these insights show a passive avoidance of decision making by individuals, while others show anomalies when individuals make active choices regarding investments.
Behaviorists have determined that individuals have certain proclivities and tendencies that forestall them from even approaching the subject and initiating action that is in their longterm interest. But even if individuals surpass the passive factors resulting in inactivity, their active choices are less than optimal and reflect certain active choice biases
How does the fact that individual investors are loss-averse tend to be problematic for individual investors when making decisions about their retirement investments?
Research indicates that individuals suffer more remorse as a result of losses than they experience satisfaction or pleasure for their gains.
Essentially, individuals do not equally rate gains and losses of equal magnitude. It has been found that, on average, if a gain and loss were of the same magnitude, individuals felt more remorse for losses by a factor of two or 2.5 times the satisfaction felt for a gain. The implication of this finding is that convincing individuals to forgo present consumption for a future payment at a later date may be difficult. In short, it is a challenge from the outset to convince many individuals to save for retirement.
Define what is meant by hyperbolic discounting and how it contributes to
participant inactivity in planning for retirement.
Apart from sheer loss aversion that results from forgoing current consumption, individuals tend to overemphasize immediate desires and rewards at the expense of their longer term needs. Not surprisingly, present needs consistently appear more pressing.
Hyperbolic discounting is the human tendency, when faced with
uncertainty, to sharply reduce the importance of the future in the decision-making process. Consequences that occur at a later time, good or bad, tend to have a lot less bearing on choices.
Survey results have shown that 25% of workers who have access to a defined contribution plan fail to contribute at all, while fewer than 10% will
contribute at the maximum level allowed under the law. Furthermore, consumption levels tend to progress upward as income levels increase. Individuals have a proclivity to spend more as they earn more.
Are procrastination and inertia factors in impeding individual participant action
when it comes to retirement planning?
Yes.
Inactivity in decision making tends to have a “stickiness” that demands more effort to overcome once a decision is delayed, deferred or avoided.
Procrastination may result from a bias toward the status quo At times, a decision to maintain the status quo may make rational sense, but at other
times, particularly when the cost of a delayed decision is high, the preferential bias toward the status quo is clearly irrational.
For instance, when an employee is willing to forgo an employer match in a 401(k) plan, procrastination and inertia are clearly
irrational.
Explain the circumstances under which preference for the prevailing condition
because of status quo bias is irrational.
Closely related to procrastination, and perhaps overlapping with procrastination and inertia, is status quo bias.
When comparing actively making decisions or taking a positive step or decisive move, individuals have a proclivity to prefer the status quo,
or the prevailing condition.
Status quo bias is not irrational when the decision is cost-neutral or when uncertainty is so pronounced that the likelihood of a gainful outcome is highly suspect or unsure. However, an ensured receipt of an employer matching contribution within a 401(k) plan is neither a cost-neutral situation nor an uncertain outcome. Quite the contrary: It is a delayed decision carrying a very high cost, especially when the effects of compounding are considered. However, the compounding effect is probably masked due to hyperbolic discounting.
