Quote from ammo:
there is an unwritten 10 day in house rule for brokerage firms,if you(broker) are pumping abc stock,and your clients are buying,you could always buy it at the open and sell it at the close for 1/2 pt or more on the mere fact that you know they will buy,,for the stocks that they pump,to avoid this temptation, they must hold them for ten days,loosely applied, the indexes follow the same rule often,tomorrow is day ten of this little pump
where did you learn that?
