Chapter 7 Financial Markets: Risk and Investment Flashcards
Efficient market hypothesis
all of the information available at a given time should be reflected in the price of the traded securities
Noise traders
– do not behave rationally, but instead do not take some information into account, place too much value on rumours, and make many more trades than would be the case among rational traders
Passive investors
– do not behave rationally, but instead make purchases and then do not trade again for a long time, and make much fewer trades than would be the case among rational traders
Investor mistakes
- Pride: the sin of overconfidence in one’s forecasts
- Gluttony: the sin of accumulating information and the illusion of knowledge
- Lust: the sin of believing information from company executives or fund managers
- Envy: the sin of excessive self-confidence
- Greed: the sin of hyperactivity
- Sloth: the sin of credulity
Wrath: the sin of group decision-making
Disposition effect
– investors hold on to losing stocks for too long, and sell winning stocks too quickly
- Prospect theory: buying price as a reference point; more risk-seeking in loss Domain
- Reluctance to sell losing stock: disposition effect becomes smaller when participants are forced to sell after each round with the option to rebuy
• Disposition effect is lower among
– wealthy investors and professional stock traders
– more intelligent and experienced Traders
• Disposition effect can be reduced by
– positive mood
– self-control
– learning about other investors’ outcomes
House money effect
– previous gains can lead to greater risk seeking
• Stock traders sometimes do not yet consider the recently earned profits from stock sales to be their own money; easier to take greater risks
Starting low but ending high effect
– in auctions, low starting prices can lead to high final Prices
• Reasons:
– reduced entry barriers: low starting prices encourage participation in auctions and stock purchasing
– sunk costs: low starting prices entice bidders to invest time and energy in the auction or market, and to continue due to sunk cost effects
– brisk(rege) participation: bidders might conclude that particularly valuable goods are at stake, which makes them willing to pay a higher price
Home bias
– investors tend to select stocks from their own Country
– therefore ignore that the values of these stocks correlate more closely with one another than do the values of stocks from different countries
Incidental affect
emotions and moods that are experienced at the time of decisionmaking but have no connection to the task at hand
Integral affect
emotions and moods that are directly linked to the decision itself
– anticipated emotions: concern the consequences of a decision (e.g., delight, disappointment)
– anticipatory emotions: concern the immediate visceral reactions to risk in a decision (e.g., dread(Furcht), anxiety)
Herd behaviour
– tendency among investors to follow the behaviour of other investors blindly
• Conformity with the crowd in buying and selling stocks, even when facts do not give good reasons
Information cascades
investors ignore their private information and imitate others
Speculative bubble
– a situation where a large difference between the market price of an investment and its fundamental value occurs
Mechanisms responsible for the development of speculative bubbles
– financial contagion spread of speculative bubbles via physical cash flows in the international and global trade of goods
– mutual psychological contagion similar to the way an infectious disease spreads, investors´ emotions, attitudes and expectations ‘infect’ others
– psychological escalation similar to feedback on a microphone: external trigger (e.g., a media report) generates interest among investors; some purchase the stock; therefore, price increases; media reports on price increases generate even more interest among investors; …
Wisdom of the crowd
– a statistical effect where an aggregate collective judgment is more accurate than individual judgments
• Importantly, investing often is not independent: Process of herding usually initialized by influential people, institutions and media outlets
