What is Index Mangement and How it is Performed?

1 min read


Index management is the act of controlling an index at a particular level. This is generally performed by big funds such as FIIs or DIIs around very big events to control the index performance to avoid extreme negative sentiment or extreme positive sentiment.

In the case of Nifty 50, when a big heavy-weight stock opens with a big gap up or gap down, index managers will buy or sell shares of other stocks in the index to bring the overall index back to its desired level.

For example, if a big heavy weight stock like Reliance Industries opens with a gap up of 1%, index managers may sell shares of other stocks in the index to bring the Nifty 50 down by 0.5%. This will keep the Nifty 50 close to its desired level of 17,600.

Index managers use a variety of tools to manage the index, including:

  • Buying and selling shares of stocks in the index
  • Using derivatives such as futures and options
  • Influencing market sentiment through research reports and analyst recommendations

Index management is a complex process that is constantly evolving. However, it is an important part of maintaining the integrity of the index and ensuring that it is a reliable benchmark for investors.

Here are some of the specific steps that index managers may take to manage the Nifty 50 when a big heavy weight stock opens with a big gap up or gap down:

  1. Identify the stock that has opened with a big gap.
  2. Determine the size of the gap and the impact it will have on the Nifty 50.
  3. Decide how much to buy or sell of other stocks in the index to bring the Nifty 50 back to its desired level.
  4. Execute the trades to rebalance the index.

Index management is a delicate process that must be carried out carefully. If index managers buy or sell too many shares, it can have a negative impact on the market. However, if index managers do not manage the index, it can lose its integrity and become a less reliable benchmark for investors.

It is important to note that index management is not always successful. Sometimes, the market will move too quickly for index managers to keep up. In these cases, the Nifty 50 may deviate from its desired level. However, index managers will generally try to keep the index as close to its desired level as possible.
