KEY TAKEAWAYS

  • FII (foreign institutional investor) holdings have dropped to 17.22%, marking a 12‑year low.
  • DII (domestic institutional investor) holdings have climbed to 10.35% in mutual funds alone, helping push total domestic institutional ownership above FII levels.
  • As a result, the FII:DII ownership ratio has fallen below 1—specifically to 0.98, highlighting stronger domestic influence in Indian markets

Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs) are key players in the financial markets, particularly in countries like India. FIIs refer to investors or investment funds based outside a country that invest in its financial assets. In contrast, DIIs are investors residing within the country who allocate funds to local securities and financial instruments.

Both FIIs and DIIs significantly impact market trends and capital flow. Their investment choices are often influenced by political stability, economic policies, and global financial conditions. While FIIs bring foreign capital into the economy, DIIs contribute to domestic liquidity and stability. Understanding their roles and distinctions helps in analysing market movements and investment strategies.

In this article, we will elaborate on who FII and DII in the share market and the differences between these two concepts.

Who are FIIs?

Foreign Institutional Investors (FIIs) are institutional entities that invest in the financial markets of a country other than the one where they are registered or headquartered. The term “FII” is commonly used in India, where it refers to outside entities investing in the nation’s financial markets.

Here are some key points about FIIs:

  1. Definition: FIIs are investors or investment funds from foreign countries that participate in the capital markets of a host country. They engage in various financial instruments such as stocks, bonds, and other securities.
  2. Role: FIIs play a significant role in providing finances and capital to enterprises in developing countries. Their investments can impact market liquidity, stock prices, and overall economic growth.
  3. Trading activity: You can track FII trading activity on stock exchanges like the National Stock Exchange (NSE), Bombay Stock Exchange (BSE), and Metropolitan Stock Exchange of India (MSEI). The data includes information on their buying and selling activities in the Indian capital market.

In summary, FIIs contribute to the global flow of capital and play a crucial role in shaping financial markets across borders.

Types of FIIs

Foreign Institutional Investors (FIIs) encompass various entities that invest in financial markets across borders, contributing to capital flows and economic development. Below are the primary types of FIIs:

1. Sovereign Wealth Funds (SWFs):

  • Definition: SWFs are state-owned investment funds that are created using surplus reserves from national revenues, such as those generated from oil or other exports.
  • Purpose: These funds aim to benefit the nation's economy and its citizens by investing in diverse assets globally to achieve long-term returns.

2. Foreign government agencies:

  • Definition: These are entities or agents authorised by foreign governments to perform welfare and other services in another country.

Who are DIIs?

Domestic Institutional Investors (DIIs) are financial entities that operate within a country’s borders and engage in investment activities using funds sourced from domestic investors. Unlike Foreign Institutional Investors (FIIs), who come from abroad, DIIs are local entities that manage and deploy funds within the domestic financial market.

Here are some key points about DIIs:

  1. Definition: DIIs include various institutional investors within a country, such as mutual funds, insurance companies, local pension funds, and banks. They play a crucial role in shaping the stock market and contribute to the overall liquidity and stability of the financial system.
  2. Investment focus: DIIs primarily invest in the financial instruments and securities of their own nation. For instance, Indian mutual funds investing in Indian company equities fall under the category of DIIs in the Indian stock market.
  3. Long-term perspective: DIIs tend to have a long-term investment horizon. Their actions can influence market trends and impact stock prices over extended periods.
  4. Regulatory framework: DIIs operate within the regulatory framework of the country where they are based. They must adhere to rules set by local regulatory bodies, such as the Securities and Exchange Board of India (SEBI) in India.

In summary, DIIs are essential participants in the domestic financial ecosystem, contributing to the growth and stability of the stock market.

Types of DIIs

Domestic Institutional Investors (DIIs) refer to entities within a country that pool and invest domestic funds into various financial instruments, thereby fostering economic growth. The key types of DIIs are:

1. Indian insurance companies:

  • Definition: Insurance companies in India offer financial protection against various risks, such as critical illnesses or accidental deaths.
  • Significance: Their growing importance in the financial sector is evident through their substantial investments in the equity and bond markets, contributing to economic stability and growth.

2. Indian mutual funds corporations:

  • Definition: Mutual funds pool resources from individual investors to invest in a diversified portfolio of assets.
  • Objective: They aim to achieve investment returns in line with the risk tolerance of their investors, providing a popular avenue for individuals to partake in the financial markets.

3. Indian banks and other financial institutions:

  • Definition: These institutions include commercial banks and other entities that offer a variety of financial services such as loans, safe deposit lockers, and insurance products.
  • Investment role: Profits generated from their services are often reinvested in the stock markets, playing a pivotal role in the domestic investment landscape.

Frequently asked questions

Do FIIs and DIIs work in opposite ways?

Yes, FIIs and DIIs are often seen taking opposite positions in the market. While FIIs typically react swiftly to global trends and prefer short- to medium-term gains, DIIs tend to follow a buy-and-hold approach, especially during FII sell-offs. This often results in DIIs buying when FIIs are selling, and vice versa.

Why is there an outflow by FIIs?

FII outflows are mainly triggered by factors like rising inflation, tighter RBI policies, increased interest rates, and a stronger US dollar. Additionally, global economic uncertainties and restrictive domestic regulations can discourage foreign investors, prompting capital withdrawal from Indian markets.

How do FII and DII affect the stock market?

FIIs influence the market by infusing or withdrawing foreign capital, which impacts liquidity and investor sentiment. Their heavy buying lifts stock prices and boosts confidence, while large-scale selling often leads to corrections. DIIs help stabilise the market by offsetting FII volatility through steady, long-term investments.

How to analyse FII and DII data?

To analyse FII and DII activity, observe net buying/selling trends, sectoral investments, and volume data. Use tools like market indices and stock performance to assess their influence. Contrasting FII and DII behaviour often reflects differing economic outlooks and can help forecast market direction.

What happens when FII buys and DII sells?

Such situations can cause volatility. FII buying boosts liquidity and prices, but simultaneous DII selling may counteract the upward pressure. If FII inflows are stronger, markets tend to rise. However, heavy DII outflows may cap gains or trigger corrections depending on trade volumes.

What is the FII buying indicator?

The FII buying indicator reflects net FII activity in the stock market. A positive reading shows FIIs are net buyers, indicating bullish sentiment. A negative value suggests selling pressure and bearish outlook. It is shaped by factors like market valuations, policy changes, economic data, and global trends.

What are some recent initiatives taken by the government of India?

Recent steps to encourage investment include:

  • 100% FDI allowed via the automatic route in select sectors like telecom.
  • Establishment of an Investment Clearance Cell (ICC) under the National Single Window System.
  • Expansion of the Production Linked Incentive (PLI) Scheme to 14 sectors to attract global investors.
