Any time there is obvious anomalous activity and price movement to the upside at the last part of the day it is usually a 'rig' job or as they say .. someone 'painting' the tape. I have no idea as to why in this case of KATX. It's market manipulation anyhow.
"Anticipate this end of day buying pressure", you must be kidding. I agree it wasn't a paint job, but the "buying pressure" statement has me confused. I must be doing something wrong! And your right it don't make a bit of difference on the pinks unless someone makes references to it, like "it finished strong today".(pump) JMO
