16
Q

How can you prevent bounded rationality

A

Limit the number of suggestions made

  • small number of carefully thought through ideas
  • makes it easier for clients to select optimal offering
17
Q

How should starting out investing be approached?

A

Low risk start - with regular contributions can lead to long term habits

A high risk bumpy start can put the investor off for life

3yrs of bad returns at start = off for life

18
Q

How should an IM act during the client relationship

A

Avoid Intertia + Regret aversion by reguarly updating portfolios

sell poor performing assets / confront issues.

19
Q

What is the familiarity bias?

A

investing in assets/markets we are familiar with or consider good quality/brand names, rather than because valuations tell us to

E.g. home bias, attention grabbing stocks

20
Q

What is availability bias?

A

Relying on recent or readily available information to make decisions

This can lead to investors beleiving recent events are more likely to occur

21
Q

What is subjective scaling?

A

incorporating person scaling when calculating utility

22
Q

Why is subjective scaling used?

A

1) Everyone has a unique perception of risk
2) Holistic View (combines subjective & objective)
3) Improved decision making

23
Q

What is mental accounting?

A

the tendency for people to categorise and treat money differently depending on where it came from or how it will be used. For example, people may be more willing to spend money won in a lottery than money earned through work.

e.g. a gambler more likely to gamble in order to chase wins

24
Q

What is Prospect Theory?

A

Explains how investors make decisions that involve risk and uncertainty.

Argues that investors do not make rational decisions, due to their irrational perception of risk, gain and probability.

25
Q

What is the core idea behind prospect theory?

A

Loss Aversion

The emotion from a loss is 2x that of a gain. Therefore investors avoid loss where possible.

26
Q

What experiment proves the disposition effect

A

1) Chance of certain gain vs risky higher gain
2) Chance of certain loss vs risky lower loss

Investors avoid gambling in A, but will gamble for a loss in B.

27
Q

What is hyperbolic discounting?

A

People place higher value on immediate rewards over larger, but delayed rewards.

Sometimes referred to as Present Bias

28
Q

What is an example of testing hyperbolic discounting bias?

A

Offered £100 today, or £110 tomorrow (takes today)
Offered £100 in 30 days or £110 in 31 days (takes 31 days)

The additional day seems trivial given the long time frame

29
Q

How does present bias affect saving for pensions?

A

Requires sacrificing current income for future benefit

Immediate reduction in disposable income outweighs “abstract” future benefit

Might also explain why people pull money out early.

30
Q

How to help overcome present bias

particuarly in pensions

A

1) auto-enrollment
2) Auto-escalation
3) Target Date Funds (adjust risk automatically)
4) Give messages to investors (in their 50s - you are now maximising your gains, do not withdraw now)

31
Q

What is prospect theory?

A

A theory which challenges the notion that investors make rational decisions based upon utility.

Instead, this theory states that when faced with, gains losses and uncertain risks. Investors are irrational.

32
Q

What behaviours cause prospect theory?

A

1) Loss Aversion
2) Disposition Effect
3) Anchoring

33
Q

How do you relate prospect theory to investing?

A

Game of chance to win / lose a certain and uncertain amount. Investors gain the certain amount and gamble the loss.

This is the same as selling winners and holding onto losers.

34
Q

What do investors experience differently due to prospect theory?

A

Equal gains and losses (emotionally)

35
Q

What behaviours / outcomes happen as a result of prospect theory?

A

1) Anchoring
2) Holding onto losers
3) Selling winners early
4) Chasing past performance (overweight likelihood of rare events occurring)

36
Q

Hyperbolic discounting makes pension saving harder, what issues arise when the pension is taken?

A

1) Crystalized as early as possible (may not of finished working yet)
2) Frontload the benefits - not caring the consider later life

37
Q

How can the issues that arise due to hyperbolic discounting when taking a pensoin be mitigated

A

1) limits on how much can be crystalzied immediately
2) Pensions in the form of annuities
3) Pensions in the form of deferred annuities
