Performance and Characteristics of Swedish Mutual Funds

Journal of Financial and Quantitative Analysis 2000 35(3), 409 open access
This paper studies the relation between fund performance and fund attributes in the Swedish market. Performance is measured as the alpha in a linear regression of fund returns on several benchmark assets, allowing for time-varying betas. The estimated performance is then used in a cross-sectional analysis of the relation between performance and fund attributes such as past performance, flows, size, turnover, and proxies for expenses and trading activity. The results show, among other things, that good performance is to be found among small equity funds, low-fee funds, funds whose trading activity is high, and in some cases, funds with good past performance.

Individual Investor Activity and Performance

Review of Financial Studies 2017 30(3), 866-899 open access
We examine the daily activity and performance of a large panel of individual investors from Sweden’s Premium Pension System. We find that active investors earn higher returns and risk-adjusted returns than do inactive investors. A performance decomposition analysis reveals that most outperformance by active investors is the result of active investors successfully timing mutual funds and asset classes. While activity is beneficial for some investors, extreme flows out of mutual funds affect funds’ net asset values negatively for all investors. Financial advisors, by contributing to coordinate investments and redemptions, exacerbate these negative effects.

Institutions’ return expectations across assets and time

Journal of Financial Economics 2026 175, 104188 open access
We study the equity, cash, and corporate bond risk premium expectations of asset managers, investment consultants, wealth advisors, public pension funds, and professional forecasters. Subjective risk premia vary one-to-one with objective risk premia that are available in real time and countercyclical. Despite their significant time-series variation, several subjective equity premia vary more in the cross-section of institutions than in the time series. This heterogeneity persists both over time and across asset classes. We tie the heterogeneity in subjective equity return expectations to heterogeneous expectations about long-term equity valuations: some institutions believe that the price–earnings ratio behaves like a random walk, whereas others believe in varying degrees of mean reversion.

The missing risk premium in exchange rates

Journal of Financial Economics 2022 143(2), 697-715 open access
We use a present-value model of the real exchange rate to impose structure on the currency risk premium. We allow the currency risk premium to depend on both the interest rate differential and a latent component: the missing risk premium. Consistent with the data, our present-value model implies that the real exchange rate should predict currency returns. We find that the missing risk premium, not the interest rate differential, explains most of the variation in the real exchange rate. Moreover, our model sheds light on puzzling relations between the interest rate differential, the real exchange rate, and the currency risk premium.

Equity Return Expectations and Portfolios: Evidence from Large Asset Managers

Review of Financial Studies 2024 37(6), 1887-1928 open access
Collecting large asset managers’ capital market assumptions, we revisit the relationships between subjective equity premium expectations, equity valuations, and financial portfolios. In contrast to the well-documented extrapolative expectations of retail investors, asset managers’ equity premium expectations are countercyclical: they are high (low) when valuations are low (high). We find that asset managers’ portfolios reflect their heterogeneous expectations: allocation funds of asset managers with larger U.S. equity premium expectations invest significantly more in U.S. equities. The sensitivity of portfolios to expectations seems to be muted by investment mandates and is smaller than the one predicted by a standard portfolio choice model.

Pricing Currency Risks

Journal of Finance 2023 78(2), 693-730 open access
The currency market features a small cross‐section, and conditional expected returns can be characterized by few signals: interest differential, trend, and mean reversion. We exploit these properties to construct the ex ante mean‐variance efficient portfolio of individual currencies. The portfolio is updated in real time and prices all prominent currency trading strategies, conditionally and unconditionally. The fraction of risk in these assets that does not affect their risk premiums is at least 85%. Extant explanations of carry strategies based on intermediary capital or global volatility are related to these unpriced components, while consumption growth is related to the priced component of returns.
