This model uses the signals from the iM-Best(SPY-SH) Market Timing System, substituting the Canadian ETF XIU for SPY and switches between XIU and Cash instead of SH. XIU tracks the S&P/TSX 60 Index and currency is Canadian Dollar.
We calculated (XIU-Cash) using XIU dividend adjusted closing prices from YahooFinance for the SPY investment periods according to Best(SPY-SH). (XIU-Cash) would have provided an annualized return of 12.2% versus 3.2% for buy-and-hold from 2000-2013 from January 2000 to the end of August 2013.
There were 32 periods when the model was invested in XIU, with 25 periods producing a positive return.
The excel file showing returns for both XIU and SPY can be downloaded here. In the spreadsheet SPY also uses dividend adjusted closing prices from YahooFinance and no slippage or transaction costs were taken into account. (SPY-Cash) produced higher returns than (XIU-Cash), but the market timing significantly improved returns for (XIU-Cash).
