I'm not exactly sure what your asking, but basically randomness in returns decreases as you increase the sampling rate (i.e. annual returns are more normal than say minutely returns). This is due basically to the fact that the more activity happens between measurements. (I could be misunderstanding your question.) High frequency measurements of prices often exhibit regularities that result from the trading mechanism e.g. bid-ask bounce.

"Analytics is often the single largest infrastructure expense for a company." I'm interested in seeing some supporting evidence. Listed references do not refer to any study or real evidence. This may be true for companies that entire strategy is analytics or ad-based. (See Deloitte 2014 CIO survey -- lots of companies not even doing analytics or feel they are not spending enough on analytics.)
