‘Hell on Fire’: The 3x leveraged Universal Investment Strategy

leveraged universal investment Strategy

-Aggressive leveraged version of our previously published Universal Investment Strategy
-Variable SPY-TLT allocations dynamically adapted to the market conditions.
-45% annual return with a Sharpe Ratio of 1.3 since 2002.

Due to its simplicity and low correlation to the S&P 500, there is a continued interest in the UIS version that uses 3x leveraged ETFs: ETF SPXL (Direxion Daily S&P 500 Bull 3X Shares ETF) and TMF (Direxion Daily 30-Year Treasury Bull 3x Shares ETF). Following the suggested nomenclature by Al from AAII SV – and to honor their interest, we call this version “Hell on fire”, which alludes to the high risk/return profile of the strategy. We will show ways to blend this strategy in a well-balanced and risk-optimized portfolio as to overcome the generally negative perception of private investors towards leveraged ETF.

For our „All Strategies“ Subscriber who use the Portfolio Builder to blend their own mix of Logical Invest Strategies, here some updates and a short mid-year review:

We have now included the “World Top 4 Strategy” into both the online an offline tool. To keep the charts readable, we opted for replacing the Aggressive Version of our “Global Sector Rotation”.

The NASDAQ 100 Meta-Strategy – Stock Selection and Compact Meta-Strategy


Intelligent Algorithms run two prallel sub-strategies.
Meta- layer chooses between the two sub-strategies based on current market conditions.
Variable allocation to Treasuries provides protection from large drawdowns.

This strategy is a good fit for investors that want to invest intelligently in the U.S. equity market as well as for stock-pickers looking for a rules-based growth strategy.
The strategy can also complement our existing strategies and can work well with our more conservative strategies like BRS (bond rotation), the BUG or with non-U.S. equity strategies like World Top 4.

The Gold Currency Investment Strategy

  • The Gold-Currency strategy trades Gold vs 3 major currencies.
  • It is based on the negative correlation between Gold and the U.S. dollar Index.
  • It is an excellent addition to existing equity or bond portfolios as it holds very little correlation to either.
  • It can be traded using ETFs, Futures or even low-margin/low-cost FX pairs.
