Rethinking Personal FinanceDuncan Gilchrist, PhD
If you check the market once a year, what fraction of the time would it be down relative to when you last checked?
Reality (by time interval):
If you invested $1 in 1870, what would that be worth today?
Cyclical Behavior
Top Mistakes
1. Bad behavior (e.g., performance chasing)○ DALBAR: Cost of market timing ~ 5% / yr
2. Bad investments (e.g., high fees)○ White House: Cost of conflicted advice ~ 1% / yr
$100k growing at 6% for 30 years → $600k
$100k growing at 0% for 30 years → $100k________ $500k
Diversified portfolio grows at about 6% / yr
Tragic Consequences

Two Questions
1. How to optimize? Figuring out which option to pursue.
2. How to execute? Actually pursuing that (or any) option.
Need a model & data. Difficult to optimize when:
1. Little information is available
2. Activity is done infrequently, so limited feedback
3. Activity takes a long time to complete and/or feedback that is received is lagged
4. Significant uncertainty or high volatility in outcomes
Optimization = Cognitive + Behavioral Challenge
Execution = Optimization at Micro-scale.
Need to prioritize & be motivated. Difficult to execute when:
1. Activity is optional
2. Activity must be repeated frequently
3. Activity results are difficult to measure
4. Activity doesn’t yield immediate gratification
