How to Use Factsheets to Identify Window Dressing in Mutual Funds

Checking how to check mutual fund performance in India starts with one free document every fund house publishes monthly: the factsheet. But most investors skim past it. That is a mistake. Factsheets hold clues that reveal if a fund manager is dressing up the portfolio right before reporting dates.

Window dressing means a fund manager buys popular, well-performing stocks just before the month or quarter ends. The goal? Make the portfolio look smarter than it really was. Then, after the snapshot date, those stocks quietly get sold.

This guide gives you a step-by-step method to spot window dressing using nothing but publicly available factsheets.

Step 1: Download the Latest and Previous Factsheets

Every mutual fund house in India uploads monthly factsheets to its website. You can also find them on AMFI India. Download at least three consecutive months for the same scheme.

Why three months? Because one month of changes could be genuine rebalancing. But when you line up three months side by side, patterns become visible. Stocks that appear and vanish within a single month are your red flags.

Step 2: Compare the Top 10 Holdings Month Over Month

Open the factsheets and look at the top 10 holdings section. Write them down for each month. Then ask yourself:

1. Did any stock appear in the top 10 this month that was not there last month?
2. Did any stock vanish from the top 10 that was present for the previous two months?
3. Are the new additions stocks that recently rallied hard in the market?

A fund manager who genuinely likes a stock will hold it for months. A window dresser buys it just before the cut-off, so it shows up in one factsheet and then disappears.

Step 3: Check the Sector Allocation Shifts

Factsheets show sector-wise allocation as a percentage. Compare sector weights across months. If a sector suddenly jumps from 2 percent to 8 percent and then drops back, something is off.

For example, say IT stocks had a massive rally in February. If a mid-cap fund's IT allocation spikes in the February factsheet but returns to normal by April, that is a sign. The fund manager likely loaded up on IT names to ride the optics of a hot sector.

Genuine portfolio shifts happen gradually. Window dressing happens in sudden bursts.

Step 4: Look at the Portfolio Turnover Ratio

The portfolio turnover ratio tells you how frequently the fund manager buys and sells holdings. A high turnover ratio means the portfolio changes often. Find this number in the factsheet, usually near the bottom or in the scheme information section.

• A turnover ratio above 100 percent means the entire portfolio was replaced in a year.
• For a large-cap fund, anything above 60 to 70 percent deserves scrutiny.
• For a mid-cap or small-cap fund, ratios above 80 percent should make you cautious.

High turnover plus sudden top-holding changes equals a strong window-dressing signal.

Step 5: Cross-Check with How to Check Mutual Fund Performance in India Using Returns Data

Now compare what the factsheet claims against actual performance numbers. If the fund's top holdings look impressive but the fund's trailing returns are mediocre, something does not add up.

Check the fund's 1-month, 3-month, 6-month, and 1-year returns in the factsheet. Then compare these with the benchmark index returns listed right next to them. A fund that consistently lags its benchmark despite holding popular names is likely engaging in cosmetic portfolio management.

You can verify returns independently on the SEBI website or AMFI's portal.

Step 6: Check the "Other" or "Below Top 10" Holdings

Most investors only look at the top 10 stocks. But the real story often hides below. Factsheets sometimes list the complete portfolio or at least the top 20 to 25 holdings.

Look for stocks ranked 11 through 25. If these are obscure, illiquid names while the top 10 are all blue-chips, the fund might be using a barbell approach — or it might be dressing the window with well-known names on top while the actual bets sit lower.

A consistent, conviction-driven fund will show coherence between its top and bottom holdings. A window-dressed fund will show a split personality.

Step 7: Watch the Reporting Calendar

Fund factsheets in India are dated as of the last day of each month. SEBI requires portfolio disclosure on a monthly basis. The most common window-dressing periods are:

• March end — financial year close, maximum scrutiny from investors.
• June, September, December end — quarter-end reporting dates.
• Any month with heavy NFO launches — fund houses want existing schemes to look good.

Pay extra attention to factsheets published right after these dates. The changes you see were made right before the cut-off.

Common Mistakes Investors Make

Trusting one factsheet alone. A single snapshot tells you nothing about behavior over time. Always compare at least three months.

Ignoring the expense ratio. High turnover from window dressing costs money. Those transaction costs eat into your returns even if the factsheet looks pretty.

Assuming big names mean good management. Holding Reliance, TCS, and Infosys does not automatically mean the fund is well-managed. What matters is whether those names were held consistently or just bought for show.

Not reading the fund manager commentary. Some factsheets include a brief note from the fund manager. Read it. If the commentary talks about long-term conviction but the portfolio churns monthly, that mismatch is telling.

Quick Tips to Protect Yourself

1. Download and save factsheets every month. Build your own archive.
2. Use a simple spreadsheet to track top 10 holdings over six months.
3. Compare portfolio turnover ratios across similar funds in the same category.
4. If you spot window dressing repeatedly, move your money. There are plenty of honest fund managers.
5. Combine factsheet analysis with trailing return comparison for a full picture.

Window dressing is legal but dishonest. It misleads you into thinking a fund performed differently than it actually did. The factsheet is your free audit tool. Use it every month, and you will see through the tricks that most retail investors miss completely.
