> How do real quant traders deal with this discrepancy? A lot of it comes down to access to information and speed. All the major traders and quants have access to what effectively boil down to mailing lists (that their companies pay top dollar for) that have the best analysts in the world producing in-depth analysis on various topics[0]. Also, many/most have access to a Bloomberg terminal[1] to get the Bloomberg new feeds and the AIM clone, which costs $25,000/year/person. This is why amateur day-trading is silly. You're not competing in a level playing field- they know more than you do.
