The power of diversification: Portfolio Diversification with Logical Invest Strategies

Diversification is a cornerstone to successful investing. In simple form, when measurably diverse assets are combined in a portfolio, the investors portfolio risks are reduced without any sacrifice of returns. This is a rare “free lunch”, it is well accepted part of modern financial portfolios, and to stay financially healthy it is important not to skip lunch. When one asset is going down while the other is going up, the portfolios risk is reduced without the normal penalty of risk/return trade-offs. We take advantage of that when our systems dynamically blend things like the S&P 500 and treasury bonds, which often exhibit negative correlation to each other (which is ideal). Applying Portfolio Diversification to Strategies: Our subscribers can take this take a step further. Our investing algorithms take on a blend of the properties of their underlying assets combined with the “alpha” edges from the investing rules. The returns of each investing strategy should be thought of as an asset, which are different and unique from the underlying holdings. So holding a portfolio of strategies functions much like holding a portfolio of assets. To evaluate the risk profile of the strategy, we examine the history of the returns of those strategies, much like when holding a basket of stocks the historical returns of each stock would be evaluated.

Correlation – Still the grand lady of Portfolio Diversification

It has been now 18 months since our post on “The power of diversification: Portfolios of Logical Invest Strategies”. Back then our main argument for diversification using a robust portfolio of several of our strategies was that “diversification is ‘a rare free lunch’, it is well accepted part of modern financial portfolios, and to stay financially healthy it is important not to skip lunch”. Several new strategies have been published since then, among them the “NASDAQ 100” strategy, the “Gold-Currency” strategy and our “Hell on Fire”, the 3x leveraged Universal Investment strategy. At the same time, we went through the bumpy start into 2016 and most recently the waves created by the BREXIT referendum. Does our stated hypothesis of formerly presented portfolios still hold true? How have the individual components performed, and most importantly, have they added value through low correlation? Have new optimum portfolios emerged since then?

Build Custom ETF Portfolios: Mid Year Review Portfolio Builder

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 preconfigured and optimized Markowitz Portfolios have been updated, only slight changes in the allocations occurred – all are <5%, so in most cases these can be neglected due to account size.

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

Summary: -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.
