Maybe they already have been. Despite the dropping price there has been accumulation. Yesterday was on pace for a 4 million share day with little price movement. One of my mentors calls that kind of activity a "silent alarm" showing accumulation. Because the volume faded dramatically at the end only those watching intraday would see it.
Our EOD had heavy sells into the close for several days in a row but not the kind of volume that would foretell a sell off. What it did do was continue the downward momentum until we arrived at a low volume day like today (really a continuation of yesterday's fade).
1/5 of the volume (albeit a low day) came in the last 20 minutes with that little bump at the end 2 seconds before close to point it upward. Was that a signal? We'll see. I think once retail is done selling the PPS will rise until retail jumps back in. Then the money players will shed some shares to shake out the retail again....until permit arrives and the real games begin.
