iMarketSignals – improve investment performance

We provide unbiased guidance to market direction. Our models can be classed into following  groups:

  • Leading recession indicators:
    • BCI is a Business Cycle Indicator optimised to identify a looming recession constructed from economic data series.
    • COMP is a recession indicator model constructed by combining third party leading indicators.
  • Buy and Hold investing. These models are macro by nature; trading signals from the models occur infrequently and are un-hedged – one does not have to trade constantly in and out of the markets.
    • MAC-US is a moving average crossover model for the S&P500.
    • MAC-AU is a moving average crossover model for the Australia All Ordinaries Index.
    • BVR is a bond market model based on mathematics alone.
    • Yield-Curve is a trend-following model.
    • GOLD is a rate-of-change trend-following model.
    • SILVER is a rate-of-change trend-following model.
  • Active weekly trading models based on a proprietary ranking system updated each week to generate un-biased and un-hedged buy- and sell-signals.
    • iM-BestX are weekly trading models based on the S&P 500, S&P1500 and Russell 1000 stock index series.
    • iM-Best(SPY-SH) is a market timing model, updated weekly on Sundays for the coming week.
    • iM-Best1(Sector SPDR) is a rotation system for the Select Sector SPDR® ETFs that divide the S&P500 into 9 sectors.
    • iM-Best(SSO-TLT) is a ETF switching system based on market timing.
    • iM-Best Combo3 is a combination model of Best(SPY-SH) + Best1(Sector SPDR) + Best(SSO-TLT), updated weekly on Sundays for the coming week.

The models are updated weekly and the charts depict the state of the various markets. They can be seen by registered/logged-in members.

The models have all been published. Before the models were available on the internet, weekly updates for the IBH, MAC, BVR and Yield-Curve were sent by email to subscribers for about two years – here are some of their comments:


This model and your fine work has been quite remarkable (and profitable). I have been enjoying your observations for quite some time. Job well done.
Edward Chrusciel

Your system looks pretty good. In fact, I was amazed by the high percentage winning trades and the very low drawdowns. I’ve never seen anything like that in a MA system.
Tom Swiatek

Regardless of which version one uses, it’s a powerful system. And it answers one of the most troubling worries that investors have. It efficiently gets them out of harm’s way when the market crashes.
Erik Conley

Thank you for your unique and excellent work. We will appreciate receiving your Modelling updates. Thanks!
Chuck Szkalak

The average investor reads the financial news and thinks that gives him an edge. That only tells him what everyone else knows and is worried about. We follow the excellent work of Georg Vrba, who has a top-rated coincident recession indicator as well as a successful stock/bond asset allocation model. Here is his most recent comment:  “My own composite short leading economic indicator, which has the  highest score of all indicators so far tested, does not support the notion of a recession anytime soon.” I listen to Georg, and you should too.
Jeffrey A. Miller, PhD, President NewArc Investments, Inc.

I took that S&P buy signal of yours with a little $50K futures contract and am very happy thank you.
Dwaine van Vuuren – CEO of PowerStocks

I have read and studied all your articles with interest. I have learned much from your perspectives and will continue to follow your work.
David Hamilton

Thank you for all your outstanding analysis. Let me say that I couldn’t agree more that data beats opinion.
Dave Lincoln

Georg Vrba asks whether the ECRI is still relevant. Great analysis and charts.
Jeffrey A. Miller, PhD, President NewArc Investments, Inc.


I very much liked the write up on your models, and if I may add these have a particular appeal and interest having been developed by a fellow engineer.
Paul Willis

Have seen so many manipulate data to fit their predetermined biases and love the way you methodically deconstructed the moving averages to debunk this one. It shows the difference between intellectual laziness and intellectual rigor which you fit to a tee.
Kuosen Fung, CFP®

Your work is really interesting and I’d love to receive your updates or any other information you publish. I honestly think your results indicate there is a way to time stock and bond market exposure. Most likely people will remain human and many will follow their “gut feel” or let fear or greed override any mathematical analysis. This is why your methods will most likely continue to work.
James Schwartz, CFP®

Georg Vrba, whose excellent work on recession forecasting has helped our readers, has two different market-timing methods. His most recent article explains that the next great bull market might already be here.
Jeffrey A. Miller, PhD, President NewArc Investments, Inc.

… as always love your analysis! Always eager for Friday’s just to receive your reports!
Jose R Barcelo

I agree with your viewpoint that mathematical models provide better guidance to market directions than financial experts. Thanks so much!
C.T. Wu, PhD in EECS

I just read your article on identifying recessions. Great work!
Richard G Greenwald, AAMS, CRPC

I appreciate using math to model financial behaviour and appreciate your good work.
Richard E. Hamrick, CFA®

This time it is perma-bear Albert Edwards warning investors about the “Ultimate Death Cross” taking the S&P 500 back to 666. Georg Vrba takes the analysis even further. He shows that Edwards’ prediction is almost impossible to accomplish if you actually do the math on the moving averages involved. In addition, he demonstrates that the current indicator conditions are actually bullish based on historical data.
Jeffrey A. Miller, PhD, President NewArc Investments, Inc.

I have great respect for your work and am grateful to be included on your list.
Marvin Snyder

I have your historical charts going back and it is great material. I appreciate your insights. Steve Wenstrup


I have been following your work for some time and have been very impressed.
Steve McCarthy, CPA, CFP®

I’m impressed that you provide this much analysis each week. Thank you for your insights. Your charts are beautiful & clear.
Brett Bowman

I am really impressed by your work and liked very much your last research on gold and silver. It’s good to see that you are expanding the scope of possible investments.

The iM Tax-Efficient Seasonal ETF Switching Strategy

  • This strategy exploits the anomaly that Cyclical Sectors and Small Caps perform best from November to April, and Defensive Sectors do better from May to October during most years.
  • Three identical models starting 6 months apart are used. Each model holds only one ETF for 18 months selected by a simple ranking system from the cyclical and defensive groups.
  • The effect of this is that the combination model always has 66% of the portfolio in the “correct” direction, defensive or cyclical, and 33% in the “wrong” direction.
  • The combination model trades only twice a year, switching only one position at the end of April and end of October.
  • For the approximately 18.5 year period from end of Apr-2000 to Sep-2019 the backtest showed an annualized return of 12.3% with a maximum drawdown of -24%.

A Profitable Investment Strategy When The Yield Curve Inverts

  • An interest rate environment in which long-term debt instruments have a lower yield than short-term debt instruments of the same credit quality is considered to be a predictor of recessions.
  • Prior to recession it is advisable to exit the stock market and invest in U.S. Treasuries instead; in this strategy using as proxies ETFs (SPY) and (IEF), respectively.
  • This model uses the 2-year and 10-year U.S. Treasury yields as measures of short-term and long-term rates, respectively, and calculates the Forward Rate Ratio (FRR2-10) between the two rates.
  • FRR2-10 is the ratio of the rate at which one can lock in borrowing for the eight year period starting two years from now and the current ten-year rate itself.
  • Currently the FRR2-10 is near 1.0 signifying that US economic activity is near the end of the expansion phase of this business cycle.

The Almost Risk-Free Investment When The Yield Curve Inverts

  • Prior to recession the yield curve becomes inverted, as indicated by the Forward Rate Ratio between the 2-year and 10-year U.S. Treasury yields (FRR2-10) being less than 1.00.
  • Currently the FRR2-10 is 0.998 and the smoothed FRR2-10 is 1.016 signifying that US economic activity is near the end of the expansion phase of this business cycle.
  • When FRR2-10 falls to near 1.00 the transition from expansion to boom occurs, as during boom times the Federal Funds Rate (FFR) is increased to slow the economy.
  • After the boom period comes the recession, on average 14 months after the FRR2-10 becomes less than 1.00, and concurrently the FFR is lowered.
  • An almost risk-free investment is to buy 2-year Treasury bonds when the FRR2-10 is close to 1.0 and to sell when the FFR is at its lowest after recessions.
  • Good Returns From Switching Between High Yield Bonds And Treasuries According To Stock Market Conditions.

    • The iM-Bond Market Trader exploits the fact that, generally, when equity returns are good high yield bonds outperform investment grade bonds.
    • When equity performs well the model invests in one of the high yield bond ETFs HYG, JNK, or EMB.
    • If stock market climate deteriorates the model switches to Treasury Bond ETF IEF.
    • Backtesting over the preceding 20 years the model showed a simulated annualized return of 14.6% with a maximum drawdown of -9.6%, versus 5.0% and -9.3% for benchmark ETF BND, respectively.
    • Simulations also show that the model’s returns over any calendar year are positive and exceeded those of BND.

    This model uses only four fixed income ETFs:

    The iM Minimum Volatility (USMV) – Investor

    • Since the launch of IM-Best12(USMV)Qx (x=1,2,3,or 4) in 2014, these models converged to a combined holding of 18 stocks, thus future performance of each of the models is expected to be very similar.
    • There is not much to be gained by following four similar models and these are now replaced by the iM Min Volatility(USMV)-Investor.
    • This model holds 10 equal weighted stocks and the simulated performance since 1/3/2013 shows an annualized return of 22.0% versus 14.3% for SPY and an annual turnover ratio of 60%
    • As from Sunday 7 July we will disseminate to Gold Subscribers any buy/sell signals this model generates.
