Logical Invest 2.0: Strategy & Launch of new application

  Dear Subscribers and followers, It all started on the beautiful Greek island of Hydra where Frank, Vangelis and Alex met for the Logical Invest partner meeting in May 2018. Our objective was to define Logical Invest's strategic priorities along with the concrete steps to accomplish them. Here is what we came up with: Priority 1: Become the “partner of choice” for both retail and institutional investors Make QuantTrader the engine that drives our online offerings as well as our strategy design and operations Launch our next generation web application that merges the capabilities of our various tools into an integrated application built on a sustainable and scaleable platform Build community collaboration features so users can build, share and improve QuantTrader investment strategies and portfolios with the help of fellow investors Priority 2: Broaden our retail customer base Provide "point and click" investment options for investors looking for simple solutions Provide easy to use tools for advanced investors to create custom portfolios that meet their unique investment goals Provide better documentation and educational support to our users Priority 3: Expand our offerings for institutional investors and money managers Strive for GIPS certification of our strategies Partner with US based registered investment advisers to offer money management products Explore non-US based money management offerings including managed accounts and open investment funds “Wow, not bad for a week” we thought, but also quickly realized that to accomplish our goals we needed to expand our team with a technology veteran, while keeping the spirit of who we are.  We did just that with the addition of Patrick Hill, who joined the partnership in August 2018. Pat has held software engineering and management positions at companies such as IBM, Dell and HP as well as several start-up companies. He is a graduate of the [...]

Portfolio Builder Allocations 2018 – Set yourself up for success

First of January 2018 after a fabulous year in the markets and hopefully also your account. What better time than to spend some hours on revisiting our portfolio allocation to be ready for whatever the new year will bring? As stated previously we update and re-optimize our fixed-weight portfolios in the Portfolio Builder about twice a year. To recap, why do we re-optimize portfolios periodically? Modern Portfolio Theory by Harry Markowitz uses past returns and covariances to construct portfolios which optimize the expected return and variance. While fundamental MPT aficionados would advise to stick to your allocation for several years, at Logical Invest we advocate for a more flexible approach with regular reviews which in our view ensure your portfolio allocation considers also recent market developments. 2017 has been marked by steadily increasing equities while subdued volatility is taking historical levels. SPY, our proxy for the S&P 500 has returned 21.7% while TLT, proxy for the 20+ year bond market has returned 9.2% . The “fear index” VIX, representing S&P 500 volatility, has seen readings in the lower tens most of the year, a historical low of 8.84 and only four spikes above 15, which is the 10 years average. How have our individual strategies performed so far? The strong run in equities coupled with low volatility has provided clear medium-term trends and therefore runs to our high-performing strategies. For example, the Maximum Yield strategy returned close to 65%, this thanks to being in average two thirds invested into ZIV, which alone represents around 48.0% of this return. How has this translated into our Markowitz optimized Portfolios? 2017 has been a mixed picture for the pre-configured portfolios. As some strategies like the Maximum Yield and 3x Universal Investment performed well at or above the historical levels, others performed below [...]

Why Work Yourself, If Silver Can Work For You? (My Silver Strategy)

In the past 20 years I traded nearly everything you can trade, including commodities. Since about 10 years, I have gone from purely emotional trading to systematical rule-based trading. Today, I don't trade anything anymore, if I cannot reproduce a positive backtest of my trading strategies. Today I stopped trading commodities, because it is very difficult to get good results with backtested strategies. My core investment strategy is the "Global Market Rotation Strategy", which I presented in my first Seeking Alpha contribution. This is a very good and safe strategy and also this year the return is already 28.4%. The only commodity I trade at the time is Silver. With Silver it is different. There is no way to include silver in a successful rotation strategy. Silver is much too volatile and it is much too easy for big investors or banks to influence the price. However, one thing I still think I understand is the value of something. I do not like value investing with shares, because shares can go to 0. With commodities it is different. Today you can buy silver for $22/ounce and we know that production costs are between $25-$30. Even if there is no shortage of silver at the moment, I think for a longer term investment silver is extremely interesting. No commodity ever remained for long time below production cost. With such a constellation the downside risk of the silver price is much smaller than the possibility of higher prices. The other interesting argument for a silver investment is, that silver is extremely cheap to buy. I am using a broker (Saxo-Bank) in Switzerland which allows you to trade silver like a Forex currency. I can buy nearly every amount of silver with extremely tight spreads and no initial margin is required. With [...]

Get Back Adjusted Historical Data for Amibroker using Python and Tiingo api

In this post I will share a quick way for Amibroker users to update quotes using split and dividend back adjusted data from a fairly new provider, Although we do run our investment strategies on our very own QuantTrader, we use various other tools to analyse markets, including Amibroker. The problem: Where to download dividend adjusted data Many Amibroker users build strategies that rely on dividend adjusted historical data. At this moment it is difficult to find similar data since Yahoo, as well as many other sources, do not back-adjust prices to include dividends. A solution is to use free (or rather donation-based) EOD data from What happened to the free Yahoo finance historical data? Yahoo! finance has changed their Yahoo Finance API and the way the data is delivered. This has disrupted the workflow of many self-directed investors that use Excel or Google sheets to track their holdings. It has also created problems for users of financial software that use Yahoo's service. The service has not been discontinued. Rather, it has been changed. You can still retrieve stock, ETF, mutual funds and currency historical data. From what we can see so far, the data is in json format, adjusted for splits but not for dividends, although the dividend information is provided in the data and can be retrieved (as of 6/3/2017). If you use Amibroker, you can use the updated Amiquote to retrieve data using the new Yahoo API. It will not be dividend-adjusted (just try to download a bond ETF like "TLT"). If you want to continue an existing workflow of dividend-adjusted data, you can try this solution. You will need: Amibroker. A free account at to get a Token # A way to run the following Python script. Tingo API  docs for daily prices:         [...]

What were the model signals?   How are the ETF Rotation Investment strategies doing lately?  We don't make you subscribe to get this information, we make it publicly available. Our new charts are now more sophisticated and updated everyday (currently with a one day lag to allow data validation).  You can view these by going to strategy page and picking a strategy, like the Bond Rotation “Sleep Well”.  Or check the Maximum Yield Strategy, or the NASDAQ100. Improved tracking of ETF Rotation Investment Strategies We have a lot of features; today I will show you a few: We now have a better way to view performance by year vs benchmark.  Analytically, I think this is much more insightful than the typical 3 year, 5 year, etc. aggregated look back.   Next, you can see how you can use the preset button on the right or directly enter date ranges on the left to view any period you want.   For example here is the longer history view: Here is the one year view for a ETF Rotation Investment strategy:  And the close in Year to date period: And, by using click into the graph the cross hairs show you each individual day, which is pretty cool: We have added nice features, but I must save some fun for the next post.  You can always track our ETF Rotation Investment strategies either on the home page, on the individual strategy pages, or in the "My account" section. Either way, we´ll put the strategy performance on top of all, finally this is why you are here, and so do we. Enjoy,  Alex

Portfolio optimization: The all new Portfolio Builder

  From individual Strategies to Portfolio Optimization Based on the interest of our followers and our own investment philosophy, we have gradually evolved from offering single quantitative strategies towards blends or portfolios of strategies. The way we visualize our own development cycle might be best summarized in a chart: Where are we on this path and where are we heading? We believe we have now a stable set of 'core-strategies', which cover a broad spectrum of both risk/performance but also trading and hedging instruments. We will continue our research on new strategies, and will also in future come up with smart ideas in that area. However, we are currently increasing our effort in blending these strategies into portfolio solutions. The "Portfolio Builder" with fixed-weight allocations is here only the first step. Developing a dynamic Strategies of Strategies (or Meta-Strategies) which smartly allocate with changing weights among a set of our strategies is one of the projects we initiated since the four of us met in mid 2014. Our thought: Quickly reacting to or even anticipating changes in the market environment by changing horses on the fly, better dealing with changing correlations of markets and constantly challenging whether one of our strategies has lost ‘steam power’ should be even better than simply allocating funds with fixed weights or even worse discretionary among strategies. To continue the enhancement of our tools towards this vision, we’ve given our fixed-weight Portfolio Builder a major overhaul and implemented many of the requested features. Key features for portfolio optimization Some of the new key features for portfolio optimization are: Equity lines according to most recent strategy review Our subscribers know that we review our strategies periodically, either because we find improvements for the execution (change of IEV to FEZ in the Global Market Rotation), or introduce newly developed [...]
