Abstract:Cross-region and cross-sector asset allocation decisions are one of the most fundamental issues in international equity portfolio management. Equity returns exhibit higher volatilities and correlations, and lower expected returns, in bear markets compared to bull markets. However, static mean-variance analysis fails to capture this salient feature of equity returns. We accommodate the nonlinearity of returns using a regime switching model across both regions and sectors. The regime-dependent asset allocation p… Show more
“…Further, Chong and Philips (2015) find that a portfolio of sector ETFs constructed as a response of sectors to economic factors performs well relative to S&P 500 index. Outperformance of sector rotation strategy is also documented in the study of Baca, Garbe and Weiss (2000); Conover et al (2005); Shynkevich (2013) and Dou et al (2014). Sector rotation studies differ, among other things, in indicators used to signal a switch from one sector to another.…”

“…They argue that, fund managers may deviate from the passive market portfolio by having their portfolio with specific industry concentration, and prove that funds that deviate more from the overall market by focusing on particular industries tend to perform better. Dou et al (2014) study asset allocation in different economic regimes across sectors in the developed countries (North America, UK, Japan, and Europe). They report positive alpha of Energy, HiTech, and Health sectors; and negative alphas of Durable, Telecom, and Manufacturing sectors both in the bull market and the bear market.…”
In this paper we investigate the risk-adjusted performance of US sector portfolios and sector rotation strategy using the alphas from the Fama-French five factor model. We find that fivefactor model fits better the returns of US sector portfolios than the three factor model, but that significant alphas are still present in all the sectors at some point in time. In the full sample period, 50% of sectors generate significant five-factor alpha. We test if such alpha signifies a true sector out/underperformance by applying simple long-only and long-short sector rotation strategies. Our long-only sector rotation strategy that buys a sector with a positive five-factor alpha generates four times higher Sharpe ratio than the S&P500 buy-and-hold. If the strategy is adjusted to switch to the risk-free asset in recessions, the Sharpe ratio achieved is ten-fold that of the buy-and-hold. The long-short strategy fares less well.

“…Particularly, Markov regime-switching (MRS) models, which are widely applied in finance and macroeconomics, suppose that an observed process is triggered by an unobserved state process. Evidence supports the statement that MRS modelling outperforms static mean-variance strategies (e.g., Ang & Bekaert, 2004;Kritzman et al, 2012;Dou et al, 2014). Quandt (1960) introduced the methodology to estimate a single switching point position for a linear regression system and the MRS model was presented by Goldfeld and Quandt (1973).…”
This paper uses the case of Spain to investigate whether and how disruptive technology impacts banking stock returns under a high volatility regime and a low volatility regime. For this purpose, a two-factor model with heteroscedastic Markov switching regimes has been applied. The results indicate that disruptive technologies have an impact on Spanish banking stock returns and that the effects are volatility regime dependent, having a relevant positive impact in high volatility regimes and a less relevant negative impact in low volatility regimes. These findings suggest that investors are informed about and acknowledge the advantages of disruptive technologies and will use their adoption as a business strategy to offset adverse market circumstances. During stable market conditions, on the other hand, Spanish banking seems to have less expectations about disruptive technology as a business strategy. To summarise, this paper provides insights into the role of the pricing of banking-related assets and has other relevant implications for investors that include disruptive technology or banking exposed investments in their portfolios.
