Most portfolios don't fail from bad picks — they fail from fees, overlap and concentration. Run this 4-box audit quarterly.
Box 1: Concentration
No single stock >15%, no sector >35%. If BBCA already 22% of your portfolio, you’re betting, not investing.
Box 2: Fees
Active reksadana 2% fee → over 20 years you lose 35% vs 0.3% ETF. Switch to index (IDX30 ETF, S&P500). Check “expense ratio” line.
Box 3: Overlap
Holding 3 similar tech funds = 1 fund + 3× fees. Paste holdings into overlap tool (we give sheet) — if >80% overlap, merge.
Box 4: Cash Drag
>20% cash beyond emergency = inflation tax. Deploy via DCA or SBN if you fear correction.

Bottom line: 15 minutes now avoids 15% drag later. Audit, trim, automate.
