The signal to change allocation comes from a regime-switching model based on the MSCI World Index. The strategy uses a {\textquotedblleft}hidden Markov model{\textquotedblright} to detect changes from a regime of high volatility to low volatility and vice versa.The authors test their model-driven dynamic strategy over the period from 1997 through 2015. They conclude that their model-driven dynamic strategy outperforms a benchmark strategy of 60\% equities and 40\% fixed-income. They further conclude that the optimal implementation of their strategy is to overly it on the benchmark strategy and to apply the dynamic approach to roughly 80\% of the total portfolio. Implementing the strategy on 80\% of the total portfolio produces the highest Sharpe ratio.}, issn = {2329-0196}, URL = {https://pa.pm-research.com/content/5/4/1.12}, eprint = {https://pa.pm-research.com/content/5/4/1.12.full.pdf}, journal = {Practical Applications} }
