I have developed a rotation strategy that I'm quite happy with. This is not a day trading scheme, it is simply an evaluation tool that chooses one out of x funds based on fund-specific EMA and ROC parameters. Nothing new or unique, but it's mine and I'm pleased. I don't expect miracles but enjoy the idea of results comparable to buying and holding equities with much lower draw downs. It is relatively simple with only 5-20 trades per year based on 20 years of back testing.
