Here's a potentially relevant quote from "The Man Who Solved the Market" by Gregory Zuckerman[0].
"One day, a data-entry error caused the fund to purchase five times as many wheat-futures contracts as it intended, pushing prices higher. Picking up the next day’s Wall Street Journal, sheepish staffers read that analysts were attributing the price surge to fears of a poor wheat harvest, rather than Renaissance’s miscue. [...] “Any time you hear financial experts talking about how the market went up because of such and such—remember it’s all nonsense,” [Peter] Brown [CEO of Renaissance Technologies] later would say."
