I don't hold DODBX because it's "a dividend fund" (which it's not); I hold it because it's a fund that delivers on its promise: "The Fund seeks regular income, conservation of principal and an opportunity for long-term growth of principal and income."
If all I focused on were dividends, then I'd have 100% of my equities portfolio invested in JNJ, PG, KO, PEP, WFC, SO, XOM, etc. As Justin has shown, holding dividend stocks has blown the doors off DODBX, CAIBX, etc.
