i wouldn't average down just to recoup your losses on an earlier position... if you think about it, "averagin down" is just taking another separate position (which you presumably hope to profit from to make up for previous losses, but this can be done by taking position in any issue not necessarily the one you lost in), in which case you might be better off evaluating that NEW position without the psychological pressure of trying to recoup losses.
