The iM-(3 pos SuperCombination+ModSum) Timer Combo for Positive Yearly Returns with Low Drawdown

  • This strategy combines the iM-3 Position SuperCombination Timer and the iM-ModSum/YieldCurve [(SPY-IEF) – GLD] Timer models equally weighted.
  • A 2000-2021 backtest shows that this combination strategy would have outperformed the SPDR S&P 500 ETF Trust (SPY), showing an annualized return of 23.9% versus 7.2% and with a maximum drawdown of 15.7% versus 55.2% for SPY, respectively.
  • The backtest also shows that this combination would have since 2000 produced only positive calendar year returns and would also have outperformed SPY over each calendar year.

    Hi Georg,
    good work and great model, as usual.
    How would the model perform without IEF ?

    I just started trial. I would be interested in the 3 POS Super combo + Mod Sum.
    Can it work for me with the $40 per month subscription? Aslo, do you have a phone number so I can talk with someone about this. Much more efficient. There is a lot to this. I little overwhelming.

    I like this model. Can you show the results if using leverage (SPY/SSO) in Mod Sum? Overall stats as well as yearly results. Thank you.
