We have had a regular drip of 25k sells in recent times - someone steadily unloading. This is OK if there are enough buyers around (obvious statement) and to an extent mm's may take stock on to their books if they expect it to move. However, they would not expect to shift much before NY so why hold it over the hols? Hence increased price sensitivity to any buy/sell imbalance at this season imho.
I don't see any reason for alarm and it might prove to be a good buying window this/next week. DYOR.
