Using Trade Brains’ Portfolio Backtesting tool, you can backtest your strategies to find out the returns that you might have got on any past investments. Here, you can test how portfolios would have performed if you’ve invested in different stocks with varied allocations for 5Yrs/10Yrs back, before Demonetization, amid COVID19, or any other desired time frame.

This advance portfolio backtesting feature allows you to build one or multiple stock portfolios based on different allocations and backtest their performance. Moreover, you can find the detailed result and can look into the absolute returns, CAGR, Portfolio growth, Y-O-Y or M-O-M returns in stocks on these portfolios.

Example: How to perform Portfolio Backtesting on Indian Stocks?

In this example, we’ll discuss how much returns you would have got if you’ve invested Rs One Lakh (1,00,000) in four companies Asian Paints, HDFC Bank, Hindustan Unilever (HUL), and Reliance between Jan 2014 to Jan 2019.

The allocations on all four stocks can vary in different portfolios. For example, an equally distributed portfolio will have Rs 25k invested in each stock. On the other hand, you can also give different weightage to some stocks in an unequally distributed portfolio.

Let’s backtest the return on these four stocks between 2014 to 2019. Here are the steps to perform Portfolio Backtesting on Indian stocks using Trade Brains Portal:

1. Got to Trade Brains Portal.

2. In the ‘Tools’ section on Top Menu Bar, select “Portfolio Backtesting”. Else, here is the direct link to the Trade Brains’ Portfolio Backtesting tool.

3. Enter the Start Date, End Date, and Initial Amount. For this example:

  • Start Date: 1st Jan 2014,
  • End Date: 1st Jan 2019 and
  • Initial investment amount: Rs 1,00,000

4. Next, allocate funds in different stocks to build your portfolio.

For Portfolio 1 (which is equally distributed), enter (25, 25, 25,25) which means 25% of Rs 1,00,000 allocated equally in each stock. In the other two portfolios take two different uneven allocations. For instance, (40, 40, 10, 10) and (20, 20, 30,30) allocation in stocks for Portfolio 2 and Portfolio 3.

From the above table, you can see that portfolio 1 has given a CAGR return of 18.81% per year. If you have an evenly distributed portfolio with the stocks of Asian Paints, HDFC Bank, HUL, and Reliance invested between Jan 2014 to Jan 2019, your investment amount of Rs 1,00,000 would have appreciated to Rs, 2,36,819.16 by 2019.
