interesting price action today. Looking at a Bloomberg chart of the stock with volumes, it would appear there is an algo in the market (not a very good one tho), which is buying approx 200k shares every 15 minutes. Is a good indicator that someone is trying to execute a large position - it just isn't being executed in a very sophisticated manner.
your local time:
example
2:19pm 204k shares
2:34pm 210k shares
2:49pm 219k shares
seems then changed to 50k odd every 5 minutes. i would guess an insto is buying and the broker they gave the order to isn't very sophisticated with algo's
