22-4
Poor OutcomesA suboptimal result in an investment decision can stem from one of two issues:
1. You made a good decision, but an unlikely negative event occurred
2. You simply made a bad decision (i.e., cognitive error)

22-5
Overconfidence
Example: 80 percent of drivers consider themselves to be above average drivers.
![Page 6: 22-1 Behavioral Finance: Implications for Financial Management Chapter 22 Copyright © 2013 by The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649ea15503460f94ba4683/html5/thumbnails/6.jpg)
22-6
Overconfidence
Business decisions require judgment of an unknown future.
Overconfidence results in assuming forecasts are more precise than they actually are.
![Page 7: 22-1 Behavioral Finance: Implications for Financial Management Chapter 22 Copyright © 2013 by The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649ea15503460f94ba4683/html5/thumbnails/7.jpg)
22-7
Over-optimismExample: overstating projected cash flows from a project, resulting in a unrealistically high NPV, overestimating the likelihood of a good outcome.
![Page 8: 22-1 Behavioral Finance: Implications for Financial Management Chapter 22 Copyright © 2013 by The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649ea15503460f94ba4683/html5/thumbnails/8.jpg)
22-8
Over-optimism
Not the same as overconfidence, as someone could be overconfident of a negative outcome (i.e., “over-pessimistic”)

Confirmation Bias
More weight is given to information that agrees with a preexisting opinion
Contradictory information is deemed less reliable

Framing Effects
Loss aversion (or break-even
effect)Retain losing
investments too long (violation of the sunk cost principle)

HeuristicsThe “Affect” Heuristic:
Reliance on instinct or emotions
Representativeness Heuristic:Reliance on stereotypes or limited samples to form opinions of an entire group

Behavioral Finance and
Market EfficiencyCan markets be efficient if many traders
exhibit economically irrational (biased) behavior?
The efficient markets hypothesis does not require every investor to be rational!
However, even rational investors may face constraints on arbitraging irrational behavior

22-22
Limits to ArbitrageFirm-specific risk
Reluctant to take large positions in a single security due to the possibility of an unsystematic event
Noise trader riskKeynes: “Markets can remain irrational longer than you can remain insolvent.”
Implementation costsTransaction costs may outweigh potential arbitrage profit

Money Manager Performance
If markets are inefficient as a result of behavioral factors, then investment managers should be able to generate excess return.
![Page 28: 22-1 Behavioral Finance: Implications for Financial Management Chapter 22 Copyright © 2013 by The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649ea15503460f94ba4683/html5/thumbnails/28.jpg)
22-28
Money Manager Performance
However, historical results suggest that passive index funds, on average, outperform actively managed funds.
Even if markets are not perfectly efficient, there does appear to be a relatively high degree of efficiency.
