This Will Not End Well, But When?

Preface: Explaining our market timing models 

We maintain several market timing models, each with differing time horizons. The "Ultimate Market Timing Model" is a long-term market timing model based on the research outlined in our post, Building the ultimate market timing model. This model tends to generate only a handful of signals each decade.

The Trend Asset Allocation Model is an asset allocation model that applies trend-following principles based on the inputs of global stock and commodity prices. This model has a shorter time horizon and tends to turn over about 4-6 times a year. The performance and full details of a model portfolio based on the out-of-sample signals of the Trend Model can be found here.

   

My inner trader uses a trading model, which is a blend of price momentum (is the Trend Model becoming more bullish, or bearish?) and overbought/oversold extremes (don't buy if the trend is overbought, and vice versa). Subscribers receive real-time alerts of model changes, and a hypothetical trading record of the email alerts is updated weekly here. The hypothetical trading record of the trading model of the real-time alerts that began in March 2016 is shown below.

The latest signals of each model are as follows:

• Ultimate market timing model: Buy equities (Last changed from “sell” on 28-Jul-2023)*
• Trend Model signal: Bullish (Last changed from “bearish” on 27-Jun-2025)*
• Trading model: Bullish (Last changed from “neutral” on 10-Jul-2025)*

* The performance chart and model readings have been delayed by a week out of respect to our paying subscribers.

Update schedule: I generally update model readings on my site on weekends. I am also on X/Twitter at @humblestudent and on BlueSky at @humblestudent.bsky.social. Subscribers receive real-time alerts of trading model changes, and a hypothetical trading record of those email alerts is shown here.

This Will Not End Well

I have documented in the past how the U.S. equity market is undergoing a frothy advance. There are many ways of measuring froth. Goldman’s Speculative Trading Indicator has risen to its third-highest level in its own history, which will lead to a “this will not end well” condition. I don’t like “this well not end well” warnings because they only highlight the risks without the obvious signs of a bearish trigger. I would highlight Bob Farrell’s Rule 4: “Exponential rapidly rising or falling markets usually go further than you think, but they do not correct by going sideways”.

 
There is no doubt that “this will not end well”, but when? I explore the set of current risks and opportunities open to traders.
