How to Build a Low-Cost Portfolio Using ETFs 

Building a cost-efficient investment portfolio is one of the smartest financial moves you can make in today’s market. Exchange Traded Funds (ETF) have become increasingly popular among Indian investors because of their low expense ratios, diversification benefits, and ease of trading. If you’re looking to invest smartly while keeping costs low, learning how to build a portfolio using ETF options is essential starting with opening a demat account online. 

What is an ETF? 

An ETF (Exchange Traded Fund) is a basket of securities (like stocks or bonds) that tracks an index, sector, or asset class. Unlike traditional mutual funds, ETFs are traded on stock exchanges just like shares. 

Key Features of ETFs: 

• Low expense ratios  

• Real-time trading  

• High transparency  

• Diversification in a single investment  

Why Choose ETFs for a Low-Cost Portfolio? 

1. Lower Costs Compared to Mutual Funds 

ETFs typically have significantly lower expense ratios because they are passively managed. This means more of your money stays invested. 

2. Easy Accessibility 

You can buy and sell ETFs through a demat account online, just like stocks, making them convenient for beginners. 

3. Diversification at Low Cost 

With a single ETF, you can invest in a broad index like Nifty 50 or Sensex, reducing risk without needing multiple stocks.
