Mamba aka Miniforge was a package for (and now a spin-off of) Anaconda, intended for a faster environment resolution. In general mamba is [currently] more efficient than conda, esp. if you rely on conda-forge, a community-led anaconda channel Continue reading "Setting up Python-Env – mamba eats conda"
Anaconda is a very practical tool to manage the virtual environments... when it properly works. In theory, a desired configuration shall be setup seamlessly. In practice Conda may need hours to resolve the configuration and finally do it wrong. In this manual I explain how to setup a SoS Jupyter Notebook with R4 and Python38 with a TensorFlow and Spyder. This worked on 01.01.2024 Continue reading "Howto Setup SoS Jupyter in Conda – R4 and Python38 with Tensorflow and Spyder"
Today - on 24.04.2023 - Software AG stock jumped +50% due to a takeover offer from private equity firm Silver Lake, whereas Bed Bath & Beyond filed for bankruptcy. Continue reading "Bye-bye Software AG and BBBY"
Just had a look at one of my Wikifolios: the overall performance is positive but the annualized one is negative. Sorry guys (and gals): it is impossible, since the total performance is calculated according to , where is the annual[ized] return, an is the [fractional] number of years (and the latter is obviously positive). Even if you use the formula of continuous rate (which you definitely do not understand since it is slightly beyond the school math), it still cannot be so that is negative but the overall performance is positive.

Surprisingly, German real estate market is quite intransparent, since prices may (like German dialects) strongly vary even in two neighbor villages. But even the summary statistics is often misleading.
In this short study we demonstrate how one can detect an inconsistency and how it might be explained. Continue reading "GiGo Analysis Case – even Google might deliver Garbage Data"
In this post I demonstrate [the performance of] a multi-window interactive graphical dashboard, which visualizes the stock-picking signals from an ensemble of deep neural networks.
Further I describe the online deployment of this dashboard by means of Docker and Apache ReverseProxy.
Everybody, who invests quantitatively and significantly contributed to the engaged software: in partucular R, [mw]Shiny, LAMP-stack, Docker (and of course TF/keras) are encouraged to claim their free access to this dashboard (others are also encouraged to request a paid subscription :)). Continue reading "AI Stock Picking Dashboard via mwShiny in Docker behind Apache ReverseProxy"
Since DeGiro announced closure of Elle's depot on May 15, 2022 she had to optimally close her positions before this date. Unfortunately, the announcement of depot termination coincided with market correction and further macroeconomic risks due to Russian invasion of Ukraine.
Thus the achieved CAGR is just 2.06%, not 6% as pursued. Still it is much better than a bank deposit with zero (or even negative) rate and given the permanent deterioration of DeGiro the result is not that bad. Continue reading "JuniorDepot31 – Experiment Termination"
On 10.02.2022 DeGiro notified Elle that her Depot is going to be closed due to inability to run a bank account for an underage person.
This is a very illustrative case of the operational risk.

Since we did not report about Elle's progress for more than a year, the readers of letYourMoneyGrow.com might have thought that we have terminated our experiment of growing a 7 (currently 11) years young girl as an investor. Nope, not at all! As a matter of fact we worked hard on creation and test of a deep neural network for the stock (pre)selection. And it did work, our CAGR goal is (over)achieved!

Finally I harnessed Tesla K80 for my AI modeling but unfortunately the overheat brings much overheads and not by all models the GPU is superior over CPU. Continue reading "GPUs in AI – are they always cool? No, sometimes they are hot!"
