Really I can't imagine we're getting value here. The risk for these brokers pales in comparison to futures trades, yet as a % of underlying merchandise moved equity traders pay a huge amount in commission. As annoyed as I get at the commish game and paying so much I'm quite happy to be on the side I'm on, which is to say the beneficiary of lower rates. Unless we get even more consolidation in the industry, and even if we do, I think equity rates are headed much lower. Technology makes clearing very cheap, and there really is no value-added in charts, scanners, etc. To answer the thread' question: 50% last year, less this year.
