Groww Portfolio Analysis: Overlap, Risk and Real Returns

A great many Indian investors started with a monthly SIP, added a few direct stocks a year or two later, and now hold both. That is a genuinely sensible way to begin — and it creates one specific blind spot. Funds and stocks are shown as two separate lists, so almost nobody adds up what they actually own underneath. Portfolio analysis is how you find out.

The overlap nobody checks

This is the most common hidden risk in a mixed fund-and-stock portfolio, and it is almost never visible on a holdings screen. Suppose you run a SIP into a large-cap or index fund, and separately own Reliance, HDFC Bank, ICICI Bank and Infosys as direct stocks. Those same companies sit among the largest weights inside that fund. You have not diversified across two sleeves. You have doubled down on the same handful of businesses, and your real exposure to them is larger than either list suggests.

The same trap works between funds. Two large-cap funds from different fund houses can hold substantially the same top ten names. Owning both feels like diversification and behaves like one position, while you pay two expense ratios for the privilege. Only analysis that looks through to underlying exposure — company by company, sector by sector — will show you the true picture.

What your holdings screen can and cannot tell you

What AIVITTA analyses

• Concentration — the share of your portfolio, and of your risk, sitting in your largest positions. Most investors underestimate this, because a position that grew never felt like a decision.
• Sector and theme exposure — where the money really sits once you group holdings by what drives them, which is how you spot that a diversified-looking portfolio is three bets wearing ten names.
• Portfolio health score — diversification quality, allocation balance, volatility profile and benchmark alignment condensed into one figure you can track month over month.
• Volatility, beta and drawdown — how sharply your portfolio moves, how much of the market it absorbs via beta, and the deepest fall it has already sustained via maximum drawdown.
• Real returns via XIRR — XIRR computed across every instalment and withdrawal, set beside Nifty 50 over the identical period.
• Rebalancing insight — which drifts matter, which are noise, and which adjustments reduce the most risk per rupee moved. See our rebalancing guide for the framework.

Why SIP investors especially need XIRR

If you invest a fixed amount every month, an absolute return figure is close to unusable. Money invested last month has had one month to work; money from four years ago has had forty-eight. A single headline saying you are up 22 per cent hides all of that. XIRR is the calculation built for the problem: it treats every instalment as its own cash flow with its own date, then solves for the annualised rate that reconciles them. You can test it on your own numbers with the XIRR calculator.

Then compare that figure to Nifty 50 over exactly the same period. For a newer investor this single comparison is the most clarifying thing available, because it converts a vague good feeling into an actual decision: keep doing this, or simplify what you are doing.

Small portfolios still need a risk framework

There is a widespread belief that risk analysis is something you take up once the portfolio is large. It is backwards. When the amounts are small, the habits you form — position sizing, sector limits, how you behave during a 25 per cent fall — are the habits you will carry onto much larger sums later. A two lakh rupee portfolio with 60 per cent in one stock is not a small problem. It is a rehearsal for a large one.

Drawdown is worth understanding early for exactly this reason. Maximum drawdown is the deepest peak-to-trough fall your portfolio has already lived through. Knowing that you sat through a 30 per cent fall without selling — or that you have never yet faced one — tells you more about your real risk appetite than any questionnaire will. Our guide to understanding portfolio risk walks through the measures one at a time.

Getting started

1. Open a free accountAnalysis credits are included on the free tier. No payment and no broker connection are required to look around.
2. Bring your holdings inZerodha connects directly through official read-only API access. For a Groww portfolio, use your holdings statement until direct integration is available.
3. Read the full X-rayHealth score, concentration, sector exposure, beta, drawdown and XIRR versus Nifty, each explained rather than left as a bare number on a dashboard.
4. Change one thing, then re-checkThe value compounds when you re-run it. The score becomes a trend, and you can see whether a decision reduced risk or quietly added more.

On read-only access, and what we never ask for

Where AIVITTA connects to a broker, it does so through that broker's official read-only API. It can read holdings and positions; it cannot place orders, cancel orders, or move funds, because that permission is never requested. You can revoke the connection from the broker's own interface at any time. Separately, and importantly: no analytics tool should ever ask you for your broker login password or your trading PIN. Read-only API access is the safe standard, and anything else is a reason to walk away.

Who this suits

• Investors holding both mutual funds and direct stocks who have never checked the overlap between them.
• SIP investors who want a real annualised return instead of an absolute percentage.
• Newer investors who would rather learn the framework than collect tips.
• Anyone whose portfolio grew one holding at a time, without an allocation plan behind it.
