Count the bets, not the funds. Six tickers that hold the same top names are one bet wearing six labels. Diversification is what the holdings do, not how many apps you opened.

The cost is real even when no app prints it. Six expense ratios on one overlapping book is six fees for roughly one portfolio. Put the drag in rupees once and it stops being abstract.

Know your real asset mix before you call yourself aggressive. A balanced or hybrid fund you forgot about can be parking a tenth of your money in debt. The CAS shows the split you actually hold.
