Which doesn't mean it's not interesting to study :) The omnipresence of fibonacci ratios is interesting by itself. Last year, I was reading Proudhon's criticism of the speculative part of financial markets. His main objection was that speculation was adding absolutely no value to the world, by opposition to investors (who help making something useful real) and merchants (who displace products from somewhere where they're abundant to somewhere where they're scarce). It hitted me back then: actually, they do produce something, they produce data. Financial markets have produced the longest lived and most detailed dataset ever (I can't think of a bigger one, at least). Would be a waste not to try to use it.
