Buying the dips (to me) right now is dollar cost averaging up (on strength) and down (on weakness) into a position as I begin building long-term equity positions again.
I never DCA'd before, but I sure as hell will do so from now on, volatile markets or not -- a position started in November and DCA'd into since then on a major oil company is up (to my surprise) 70% since November.
Taking advantge of the 'dips' as I see them, and as long as my investment thesis for the long term with this company/sector/industry hasn't changed for the worse, I use the dips and market volatility as buying opportunities.
