Top Factors to Consider When Investing in 2025: An AI-Powered Overview

What exactly is Factor Investing?

If you are investing in mutual funds, you've likely heard about factor investing, a strategy gaining traction in 2025. Several mutual funds have launched factor-based New Fund Offerings (NFOs), which track NSE’s factor indices. But how do these differ from generic indices like the Nifty or Bank Nifty?

A factor index focuses on specific themes—like value, momentum, or quality—that historically outperform traditional market-cap indices. These themes consider factors affecting investment decisions in 2025, such as risk tolerance, market volatility, and evolving AI-powered investment strategies.

Factor funds sit between active and passive funds. Unlike active large-cap funds, where managers actively buy or sell stocks, passive funds simply replicate indices. Factor funds, though pegged to indices, involve periodic rebalancing due to their thematic nature—making them semi-passive.

They also support smarter asset allocation and help investors manage investment risks in volatile markets, offering a structured yet dynamic approach to wealth creation.

Some home truths about Factor Investing

Here are some basic home truths investors must understand about factor investing. 

1. What do we understand by a factor? A factor helps to explain or identify the unique features or characteristics that drives the returns on a stock. For example, a fund may be outperforming the index because it is in the right place at the right time. Like, if you are in a momentum stock in bull markets and dividend yield stock in bear markets; your portfolio is likely to do better. Factor investing actually isolates such factors.
   
    
2. Factors make a particular investment better or worse. But why do factor really matter. Let us say, the fund you are invested earned 18% last year against 13% for the index. You may believe that the 5% additional returns were generated by stock selection. Actually, it may have come by chance because the fund happened to be in the right factor or theme at the right time. Factor investing actually isolates factor impact.
   
    
3. How does factor investment help the investor. Remember, that in terms of cost; factor funds cost more than passive funds, but less than active funds. When investors pick a fund with clearly identified factors, it helps the investor to earn higher risk-adjusted returns compared to a pure and passive index portfolio. In short, factor funds also generate alpha, but it is not from stock selection but from factor selection.
   
    
4. Factor investing brings about a clear demarcation of the source of returns. In the past, you just classified returns into market returns (Beta) and excess returns (alpha). Now the alpha returns are further classified into factor returns (generated by factors) and excess returns (generated by fund manager selection). It helps identify what the fund manager is actually generating through stock selection.
   
    
5. To sum it up, the factor funds capture full Beta and part Alpha. The typical passive index fund only captures the beta part of the returns or the market returns. The factor fund captures market returns plus that portion of alpha that is generated by factors and thus enhances returns, by taking on slightly additional risk. These additional returns are generated on the back of a small additional cost by way of total expense ratio (TER).

A classic of a factor fund is the recently opened NFO of the Bandhan Nifty Alpha 50 Index Fund. This fund is benchmarked on the factor index (Nifty Alpha 50 Index). But, first a little more on factor funds.

Types of factors available in India today

Most of the factors are rule-based and based on these rules an index is created and the factor fund is indexed to that factor index. A quick look at some popular factors.

• A very popular factor is the Momentum Factor. This is based on stocks were momentum is currently favourable. They do well in bull markets but underperform in bear markets.
  
   
• The second factor is Low Volatility Factor. Here, the focus on stocks with volatility (standard deviation of returns) less than average. These volatility factor funds do well in range bound markets or even in bear markets. 
  
   
• The third is Earnings quality factor. Here quality companies are identified based on factors like low debt, stable earnings, above average ROE etc. These factor funds can outperform in stable and long term bullish markets.
  
   
• The fourth is the value factor, where stocks are selected based on valuation attractiveness i.e., lower than average P/E or P/BV or higher than average dividend yield. These perform better in long term range bound markets. 

These are just examples and in practice, there can be many more such factors that can be identified and invested in based on an appropriate index. 

Factor Investing case study: Nifty Alpha 50 Index

One of the popular factor indices on the NSE is the Nifty Alpha 50 index. Here is how this factor index has performed in terms of past returns.

• Nifty Alpha 50 index generated 3 year rolling returns of 17.4% annualized as compared to an average Nifty 50 return of 13%. However, this also means  higher volatility since the Nifty Alpha 50 index has average volatility of 24.6% compare to the average Nifty volatility of around 14%. It is a high risk and high return game and works best in the long run.
  
   
• The alpha (excess returns) generated by the Nifty Alpha 50 index is much more in bull markets than in bear markets or flat markets. For instance, in the bull market of 2005-2007, the Nifty Alpha 50 index generated excess returns of 146%. However, in the period post the IL&FS crisis, it underperformed the Nifty. 
  
   
• The sector exposure keeps changing this factor index. Between, September 2022 and September 2023, large cap exposure fell from 40% to 16.5%, while small cap exposure surged from 12% to 33%. Over the last 2 years, sector shift has been from IT dominated to BFSI dominated. 

These factors have, over a longer time frame, done better than normal generic indices. However, they also entail higher levels of risk and costs. The answer lies in taking a longer term approach to factor investing of 5-7 years for best outcom
