Kazerone: Averaging down means you buy a stock at let's say $10 and it then goes down to $5. You then buy more at $5 ... so it averages out at $7.50 Hope that's clear. But just to confuse you a little, the same principle applies to averaging up. You seem to be new in the market, so be careful.
It means buying more shares at a lower price to average down the price from where u originally bought from... . Always good to average down if ur looking to hold long, just wait for a good buy in price unless u see it confirming an upward movment to the 52 week agin. :-)
