What are some of the factors that explain investor portfolio tilts towards new factors?

- Investor wealth
- Indebtedness
- Macroeconomic exposure
- Age
- Gender
- Education
- Investment experience
- Hedging motives
- Sentiment

How are pricing factors recovered from a heterogeneous set of investor portfolios?

- Market clearing implies returns on portfolio factors generate pricing factors
- Returns on portfolio factors explain cross-section of returns
- Pricing factors can be recovered from sufficiently heterogeneous investor portfolios

What can drive the cross-section of investor portfolios and equity returns according to financial theory?

- Investor characteristics such as age and wealth drive portfolio cross-section
- Age and wealth likely to influence investor portfolios and equity returns

How are investor-based equity factors constructed for Norwegian retail investors?

- Equity factors constructed from detailed administrative panel data
- Panel contains disaggregated holdings and socioeconomic characteristics
- Ownership record covers over 400 stocks listed on the Oslo Stock Exchange

What are some characteristics used to define an investor factor in the study?

- Age characteristic based on average age of stock's retail owners
- Wealth characteristic based on average net worth of stock's investors
- Investor factor is a portfolio that is long stocks in top 30% and short stocks in bottom 30%

What do the results show about the average returns generated by age and wealth factors?

- Age and wealth factors generate positive and economically significant returns
- Monthly CAPM alphas of age and wealth factors are 1.06% and 0.98% respectively over the period

How is the cross-section of equity premia specified in the study?

- Three-factor model defined by age, wealth, and market factors
- Model matches pricing ability of traditional factors
- Spanning tests verify size, value, investment, profitability, and momentum factors are spanned by the three-factor model

How does the study's three-factor model perform out of sample according to the Fama and French tests?

- Out-of-sample annualized Sharpe ratio of 0.70
- Combining investor and firm factors increased out-of-sample Sharpe ratio to 0.84
- Investor factors expand mean-variance frontier compared to firm factors only

What is the average out-of-sample Sharpe ratio of the investor-based model compared to the market in Norway?

- Average out-of-sample annualized Sharpe ratio of investor-based model is 0.70
- Market's Sharpe ratio in Norway over the sample period is 0.32

What is the purpose of partitioning the sample of investors into two randomly chosen groups in the study?

- To avoid mechanical correlations arising from a single investor being used for both constructing investor factors and measuring exposures
- One group defines the age and wealth factors, while the other group's investors' factor tilts are measured

How do investors adjust their factor tilts over the life cycle according to the study?

- Progressively adjust their stockholdings and factor tilts
- Even investors in their first year of stock market participation exhibit migration in their portfolio tilts

What influences the factor tilts of investors according to the study's regression analysis?

- Age and wealth have robust effects on factor tilts even with controls
- Investors with high income beta to GDP, high debt-to-income ratio, and those prone to sentiment such as men or those with short market experience tilt away from factors

How do mature and wealthy investors differ in the characteristics of the firms they hold in their portfolios?

- Tend to hold stocks with large market capitalizations, high book-to-market ratios, high profitability, low investment, and low CAPM betas
- Young and less wealthy investors are more likely to hold volatile stocks with high share turnover and low institutional ownership

What is the main benefit of constructing equity factors from the portfolios of individual investors?

- Directly ties equity pricing to investor risks, preferences, and biases
- Offers rich information about the cross-section of equity premia compared to firm-focused factors

How does the study suggest combining investor and firm factors in practice?

- Data limitations may impact the statistical ability of a particular factor category
- By combining investor and firm factors, more accurate results can be achieved due to the complementary nature of both types

How does the study suggest that both investor and firm factors can be theoretically used to price the cross-section of stock returns effectively?

- Asset prices are determined by investor and firm characteristics in general equilibrium
- Combining both types of factors is expected to theoretically price the cross-section of stock returns accurately

What is the focus of the study when examining the direct stockholdings of individual investors in relation to equity pricing?

- It analyzes how stock portfolios of individual investors contain rich information about the cross-section of equity premia
- Unlike focusing on the price impact of trades, the study looks at how investor holdings provide insights into equity pricing sources

What does Büchner (2020) find evidence of when studying data on different U.S. institutional types?

- Commonality in investor demand
