Sadly, the abstract doesn’t include the result, so here it is so you can decide if you want to read more:

> Our main result, which is independent of the market considered, is that standard trading strategies and their algorithms, based on the past history of the time series, although have occasionally the chance to be successful inside small temporal windows, on a large temporal scale perform on average not better than the purely random strategy, which, on the other hand, is also much less volatile.

What a ridiculously formulated sentence.

TBF the four authors have names that appear to be Italian and German. They acknowledge the contribution of someone who provided DAX data (German stock index, like the CAC or Dow). And lots of subordinate clauses are common in written German, or at least a lot more common than in English.

So while I agree the sentence is rather contorted, there is a sympathetic explanation. Especially as the authors claim no institutional affiliations.

I don’t think such a sentence would be justified coming from an institution in an English-speaking country.
