Considering low NAV, Shouldn’t I buy regular plans over direct plans?

NAV of Regular Plans are lower than Direct Plans in mutual funds. Shouldn’t I buy low and sell high? In that case, shouldn’t I be buying regular plans over direct plans in mutual funds?

The NAV of regular plans is lower because it includes distributor commission and it’ll always be lower than the NAV of its direct plan counterpart. In this case, your purchase price doesn’t matter. What matters, is the rate of growth after you purchase.
