Zinseszinswunder in Action: mit 200 DM/mo. in DAX seit 1959 wärst Du Millionär

Wer in DAX seit 1959 jeden Monat 200 DM bzw. €100 angelegt hätte, wäre nun Millionär. Zwar es in diesem Fall auch viel "wenn das Wörtchen wenn nicht wär" gibt, ist dieser Fall nicht unrealistisch und bestimmt betrachtenswert. Denn selbst wenn man den Zeitvorrat nicht von 60 sondern "lediglich" von 30 Jahren hat und die Rendite "nur" von 6% p.a. erreicht, wird man zumindest die Altersarmut vermeiden!

In this post I show you how to summarize and visualize the data from Alpha Vantage for 6356 American stocks. Continue reading "Visualizing the Data on 6356 American Stocks – with R source code"

Patterns of Technical Analysis – Do They Work?

Seven years ago I tried to reproduce the results of "Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation" by Lo, Mamaysky and Wang with more recent data than they used. Lo et al come to the conclusion that the chart patterns are statistically significant (which does not yet mean their practical usability).
