according to my knowledge i think it won't help retailers at all,however this would help big players as well as manipulators,
this how it works,,,,, those days poor investors did not have enough money to buy when big players manipulate some shares... as where as they could have load such a shares in a certain degree,,, be course there were some resistance..especially not enough buying power.. but credit relaxation tend big players to easily pump and dump. since this poor retailers would use their credit to load such a shares..
thatz y market was kept down by some ones until they got what they want.the movement they got it,, defa.. they allow market to go up.but all remember this will not last for long time.
therefor please be very careful when you deal with ur credit when you do trade eventually u may end up with nothing???
