Can't Wait Any Longer

I've been waiting for a good sell opportunity and I think this is one.  I'm putting in a bit of short exposure here.  With the Greece bailout catalyst out of the way, I see no other bits of positive news that can signficantly run this market higher.  I believe strong earnings are already baked in, and there is more supply coming with IPOs, secondaries, etc.  Also, sentiment is a bit too one sided as evidenced by the heavy equity call volume relative to puts over the past couple of weeks.  Not looking for much, maybe a couple percent selloff this week.
