I think that averaging down is better suited for the long term investor, albeit an individual or a mutual fund buying value.Quote from StillStanding:
There does not seem to be any simple answer. following all the published rules doesn't seem to work either. you can probably average down in some intelligent fashion only if certain conditions exist. e.g. if original reason for getting into trade still exists.
IMO, for trading, taking a small manageable loss is far better than marrying a position and becoming that investor.
