Traders are skittish on Fridays and particularly skittish until they see what way the market is moving hence little from them on the buy or sell side. Investors who also trade like Fridays. I have a theory,buy Friday and sell early next week and it works more often than not. I accumulate freebies trading friday than on any other day of the week. I think Friday this week may have come on thursday so I bought yesterday instead. It pays to have a flexable plan. Today is still a question mark.
