This binary model uses the signals from the iM-Best(SPY-SH) Market Timing System, and switches between SPY (SPDR® S&P 500® ETF) and Cash instead of SH. This model would have produced an average annual return of about 16.3% from January 2000 to the end of August 2013, versus 2.6% for a buy-and-hold investment of SPY over the same period, with maximum drawdowns of -15% and 55%, respectively.
