How to Build a Diversified Portfolio in the Bangladesh Stock Market


Building a diversified portfolio is a fundamental strategy for managing risk and optimizing returns in the stock market. Diversification spreads investments across different asset classes, sectors, and individual stocks, reducing the impact of poor-performing assets on your overall portfolio.

In the context of the Bangladesh stock market, where investors face unique opportunities and challenges, creating a diversified portfolio is crucial for long-term success. 

In this article, we will explore the principles and strategies to build a well-diversified portfolio tailored to the Bangladesh stock market.

Understanding the Bangladesh Stock Market

Before delving into portfolio diversification, it’s essential to have a basic understanding of the Bangladesh stock market. Bangladesh has two main stock exchanges: the Dhaka Stock Exchange (DSE) and the Chittagong Stock Exchange (CSE). The stock market consists of a wide range of sectors, including textiles and garments, pharmaceuticals, banking, telecommunications, energy, and more.

Principles of Portfolio Diversification

  1. Asset Allocation:

Start by determining your investment objectives, risk tolerance, and time horizon. Asset allocation involves deciding how much of your portfolio to allocate to different asset classes, such as stocks, bonds, and cash. In the Bangladesh stock market, where stocks are often a primary choice, consider diversifying beyond equities.

Here is asset allocation formula- 

Asset Allocation (%) = (Desired Allocation to Asset Class / Total Portfolio Value) x 100

  1. Sector Diversification:

Within the stock market, sectors can perform differently based on economic conditions. Allocate your investments across multiple sectors to reduce sector-specific risks. Consider sectors like textiles, pharmaceuticals, banking, energy, and information technology.

Here is Sector allocation formula-

Sector Allocation (%) = (Desired Allocation to Sector / Total Portfolio Value) x 100

  1. Individual Stock Selection:

When selecting individual stocks, aim for a balance between large-cap and small-cap stocks. Large-cap stocks are typically more stable, while small-cap stocks may offer growth potential. Research companies with strong fundamentals, solid financials, and growth prospects.

Here how to split your stocks in small or large cap. 

For example, if you aim for 30% of your portfolio in small-cap stocks and your portfolio is 10 lakh BDT then, 

Small-Cap Allocation (%) = (30% / 100%) x 1000000 = 300000

  1. Geographic Diversification:

Consider diversifying your portfolio beyond Bangladeshi stocks. While the domestic market is your primary focus, explore opportunities in international markets, particularly in neighboring countries like India and Sri Lanka.

  1. Long-Term Perspective: 

Maintain a long-term perspective when investing in the Bangladesh stock market. Diversification is a strategy for reducing short-term risk while pursuing long-term growth. Avoid making frequent changes to your portfolio in response to short-term market fluctuations.

Strategies for Diversification in Bangladesh

Diversifying your investment portfolio in the Bangladesh stock market involves spreading your investments across various asset classes, sectors, and individual stocks. Here are some strategies for effective portfolio diversification in the context of the Bangladesh stock market:

  1. Exchange-Traded Funds (ETFs):

ETFs are a convenient way to achieve instant diversification. Look for ETFs that track major indices or sectors in Bangladesh or global markets. They offer exposure to a broad range of stocks within a single investment.

  1. Mutual Funds:

Mutual funds in Bangladesh provide diversification by pooling investments from multiple investors to purchase a diversified portfolio of stocks. Research and choose funds that align with your investment goals.

  1. Balance Large and Small Caps:

Include a mix of large-cap and small-cap stocks in your portfolio. Large caps may provide stability, while small caps can offer growth potential. Balance your allocation based on your risk tolerance.

  1. Regular Rebalancing:

Periodically review and rebalance your portfolio. As asset values change, your portfolio’s allocation may drift from your desired targets. Rebalancing ensures you stay on track with your diversification goals.

To maintain your desired diversification levels, periodically rebalance your portfolio. Calculate the required adjustments using this formula:

Rebalancing Amount = (Current Allocation – Desired Allocation) x Total Portfolio Value

For example, if your desired allocation to small cap is 20%, but it has grown to 5% of your 10 Lakh portfolio:

Rebalancing Amount = (25% – 20%) x 1000000 = 50000 

You would need to sell 50000 worth of Small cap and reallocate the proceeds to other asset classes to achieve your desired diversification.

  1. Consider Defensive Stocks:

In uncertain market conditions, consider defensive stocks in sectors like utilities or consumer staples. These stocks may provide stability during economic downturns.

  1. Dividend Stocks:

Dividend-paying stocks can be an essential component of a diversified portfolio. They offer income and potential capital appreciation. Look for companies with a history of consistent dividend payments. 

Risk Management in Diversification

While diversification is a powerful risk management tool, it’s essential to understand that it cannot eliminate all risks. Be mindful of the following:

Market Risk: Diversification reduces specific risks but not market-wide risks. Global economic events, interest rate changes, and geopolitical factors can impact all stocks.

Monitoring and Research: Regularly monitor your portfolio and stay informed about market developments, company news, and economic conditions in Bangladesh and abroad.

Review Your Portfolio: Periodically reassess your portfolio’s performance and adjust your strategy based on changing financial goals and market conditions.


Building a diversified portfolio in the Bangladesh stock market is a fundamental strategy for achieving long-term investment success while managing risk. By allocating your investments across different asset classes, sectors, and individual stocks, you can create a resilient portfolio that can weather market fluctuations and provide opportunities for growth. Remember that diversification is not a one-time task but an ongoing process that requires vigilance, research, and a commitment to your financial goals. 

With careful planning and discipline, you can navigate the unique opportunities and challenges of the Bangladesh stock market and build a portfolio that aligns with your investment objectives.
