Häusle oder Aktien? – Die Antwort gibt es aber man muss immer adhoc berechnen

Am häufigsten kommen zwei Empfehlungsarten von "Experten" vor: entweder in die Aktien zu investieren weil sie eine höhere erwartete Rendite bringen oder die Immobilien zu kaufen weil die stabiler sind.
Beide Aussagen sind lediglich ein kleiner Teil der komplizierten Wahrheit. In diesem Post zeigen wir anhand eines Beispiels, wie man - mittels Zahlen und Berechnungen - eine mehr oder weniger vollständige Antwort für seinen persönlichen Fall bekommen kann.
Sehr hilfreich dafür ist das kostenlose Toolset von letYourMoneyGrow.com

Interbreeding R and Python to Give Birth to an Optimal German Mortgage

In many countries a mortgage shall be completely redeemed to the end of its duration and may be refinanced anytime. In USA one additionally can foreclose his mortgage by mailing his house-keys to a bank. In Germany is different.
First of all, one may completely refinance a mortgage only after 10 years (otherwise one have to pay Vorfälligkeitsentschädigung - a compensation to a bank for missed interest). But taking a long-term mortgage (20 or 30 years) implies a higher mortgage rate, thus it is not uncommon to take several consequent 10- (or sometimes even 5-) year mortgages. In order to optimize mortgage costs / rate change risk relation one can take several submortgages with different durations. Last but not least there is no requirement to amortize a mortgage completely: normally one refinances the residual debt (Restschuld) with a follow-up mortgage (Anschlussfinanzierung).
In this post we discuss the challenges of mortgage optimization and show how two popular programming languages - R and Python - can help us together

Анализ одной фьючерсной стратегии – как следует действовать осторожному инвестору

В сфере управления капиталом часто возникает противоречие - трейдеру нет резона раскрывать детали стратегии, а инвестору рисковано инвестировать в то, что он не понимает. В случае работы через Interactive Brokers сформировался негласный компромис - от трейдера ожидается, что он (по крайней мере) предоставит стандартный детальный отчет IB. На примере стратегии от Юрия Чередниченко мы рассматриваем, что можно (и чего нельзя) почерпнуть из отчетности IB.
Практика показывает, что типичный частный инвестор практически не способен воспринимать результаты статистического анализа, не говоря уж о том чтоб самому провести такой анализ. Поэтому в этот раз мы намеренно обходимся без математики, аппелируя лишь к графикам и здравому смыслу
. Continue reading "Анализ одной фьючерсной стратегии – как следует действовать осторожному инвестору"

4. Münchener Tischgespräch von DSW – drei interessante Präsentationen

Auf 4. Münchener Tischgespräch, organisiert am 05.12.2019 vom Deutschen Schutzverein für Wertpapierbesitz e.V. (DSW), hatte ich die Gelegenheit, drei interessante Vorträge von Fraport (ETR:FRA), Biofrontera(NASD:BFRA) und Deutscher Post(ETR:DPW) zu hören. Obwohl ich der quantitative Investor bin, also schaue ich eher auf die Zahlen als auf die Stories, fand ich die Information sehr interessant. Darüber hinaus war es keine Massenveranstaltung, sondern wirklich ein Tischgespräch im engeren Kreis.

JuniorDepot18 – Hedging Profit by a Long-Short Lock-in

During a high-turbulence market regime it often makes sense to fix the profit quickly. However, Elle's broker DeGiro provides fee-free trades with the following ETFs only once per months. Elle's trading capital is relatively small so far (€2165), thus paying €2 trading fee shall be avoided whenever possible. So I taught her to lock the profit in long position by means of the respective inverse ETF! Continue reading "JuniorDepot18 – Hedging Profit by a Long-Short Lock-in"

Salaries in German IT Branch – a Case Study of Critical Statistics Review

Recently I have read the results of salary survey among Russian-speaking  software developers in Germany, published on dou.ua. I was skeptical about the validity of conclusions and expressed my critics (a bit less polite than I should have done it). But the survey author reasonably pointed out that he did his best in his free time and did provide the raw survey data. Recalling a popular motto in Soviet Union: if you are disagree then criticize but if you criticize then do it better I try to interpret the survey results more correctly.
