Know what you own.Ask what could happen.

Saarth is an investing research workspace from The Quant Lab. Understand what you own, explore “what if?”, and test ideas against history before you act.

Open Saarth Try a what-if

Background: illustrative simulated paths from one starting point. They show how a range of outcomes widens with time. Not market data, not a forecast.

How often do you really open your portfolio? When you do, do you understand what you see? Is someone else managing it for you, and do you know what they bought?

Saarth is for the questions you would ask if you had the time and the tools.

If bank stocks fell 10% tomorrow, would you know what it means for you?

Turn a worry into a question you can test.

Pick an index, move it, and see which holdings carry the impact, including the ones hiding inside your index fund.

See where you’re headed, then choose the route.

Adjust a goal and monthly contribution to explore a range of possible journeys. Compare two illustrative portfolio mixes and the assumptions behind them.

    Why did you buy it? Would you remember a year from now?

    Keep the reason, not just the result.

    Saarth’s decision journal keeps the reason with the move. The Chakra experience below is a concept demo of how a future assistant might help you spot a pattern and turn it into a rule you can inspect. It is not a live Saarth feature.

    Chakra is an idea for a future assistive experience. This scripted example shows how a possible pattern could be inspected before any rule is kept. It is not available in Saarth today.

    How many apps does it take to see everything you own?

    Start with the portfolio you already have.

    Bring in Zerodha (Console files or a read-only Kite snapshot), Dhan, any CSV, or add holdings by hand. Saarth combines the accounts, then shows what they add up to.

    • Combined across brokersThe same stock in two accounts becomes one line.
    • Allocation and concentrationBy holding, sector and market cap, and by the intent you give each group.
    • Risk and benchmarksVolatility, beta and worst fall against NIFTY 50 and other indices.
    • Discover and watchlistsResearch a stock and keep the ones you’re watching together.

    What Saarth won’t do.

    Tell you what to buy or sell

    Saarth shows evidence, ranges and trade-offs. The decision, and the reason for it, stay yours.

    Place orders on your account

    Broker connections are read-only. Saarth can place virtual paper orders for research, but cannot place orders with your broker.

    Predict the market

    Scenarios, simulations and backtests show ranges under assumptions you can see. They are research, not forecasts.

    saarth

    Saarth means purposeful.

    We named it for the kind of investing we want to make easier: fewer reactions to noise, and more decisions you can still explain a year later.

    The name also echoes sārathi, the charioteer who keeps a journey on course. Chakra is a concept we are exploring for the next part of that journey.

    Give your next decision a reason.
