What are the research questions?
- How does financial literacy relate to portfolio return?
- How does financial literacy relate to portfolio rebalancing choices?
What are the Academic Insights?The following insights are derived from the study:
- Controlling for various measures of portfolio risk, more literate households in the sample experience approximately 0.4% higher yearly returns compared to the least literate.
- In terms of the relationship between financial literacy and portfolio choices, there are three main findings:
- The first result is that more financial literate households do not always take more risk but their risk exposures vary with market regimes ( for example, a 1% increase in the expected excess return of risky assets is associated with a 2% increase in the risky share for each unit of financial literacy).
- The second result is that the least financial literate households passive rebalancing (based on market moves) is more important (64% of the total change in the risky share) compared to active rebalancing. Differently, for the most literate households passive rebalancing accounts for only 30%.
- The third result is that more literate households are more likely to act as contrarians (they tend to move allocations to funds that experienced lower returns in the past).
Why does it matter?Another important study, which uncovers novel mechanisms that relate financial literacy to portfolio management dynamics and outcomes.
The Most Important Chart from the Paper:
We match administrative panel data on portfolio choices with survey measures of financial literacy. When we control for portfolio risk, the most literate households experience 0.4% higher annual returns than the least literate households. Distinct portfolio dynamics are the key determinant of this difference. More literate households hold riskier positions when expected returns are higher, they more actively rebalance their portfolios and do so in a way that holds their risk exposure relatively constant over time, and they are more likely to buy assets that provide higher returns than the assets that they sell.
