Fridays are always a focus on those who want to manipulate the overall market. Some technical traders use weekly closing prices to determine their actions. It is a scare tactic to shake out those who are moved by fear and greed. It you have conviction about your position, you simply go for a walk for add to your position at lower prices. For me, I like to add to my position whenever I can. As always I make no recommendations to others and suggest that you seek the advice of a licensed professional.
