Stunning: 1.5 Percent of ALL US Trading Pass Through This One Room

(From Alphaspotting)

It is common knowledge now, that high frequency trading contributes to more than 50 percent of all trading in the US stock markets. Here is a lesser known fact – 1.5 percent of all US trading happens from one such firm – Tradeworx -

“A pioneering high-frequency trading firm, Tradeworx, has its relatively humble offices two flights up from an Urban Outfitters in a sleepy New Jersey suburb. Twenty people work there, about half of them on the trading floor, monitoring on triple screens the fractions of a penny as they mount up, second by second. Roughly 1.5 percent of the total volume of stocks traded on US exchanges on a given day will pass, however fleetingly, through the hushed, sunlit, brick-walled room.” (Source)
