> Averaging down only makes sense if the fundamental thesis hasn't changed
> Warning: averaging down a falling stock amplifies losses if the thesis is broken
> Value averaging: buy more when price is below target, less when above
> Never average down more than your position sizing rules allow (max 5–10% of portfolio)
> NFA — averaging down can turn a small loss into a large one. Know when to cut.
