In my experience (I recently bought a bond fund), the dividend increases the number of shares but decreases the price of those shares. The increase in the number of shares is offset by the decrease in price.
So, how does the dividend benefit me?
A dividend has ZERO benefit. The fund is playing by its rules and all they're doing is their fiduciary responsibility as stated in the fund rules. You don't make or lose money on the dividend payout as I stated above. The money you "made" was already there assuming the fund appreciated in value (not all do).
Now your fund either stays the same, decreases in value or increases in value. If the value of the fund is the same as last year, I'd get out of that dog & into something that makes money. If you're losing money in that fund, run for the hills. You got a loser.
Your fund maybe making money, but if your return over time is less than the average market return, I'd get out of that as well. Many claim the market average is about 7%. I have a personal floor of 10% that's my rule. If you're making around that, your fund is a solid performer.
If you're making consistently about market return, hang onto that baby or buy some more. That fund Manager is a star.
