Detailed Explanation:

Answer: Option 4 — Participatory Note

Participatory Notes (P-Notes) are financial instruments issued by registered Foreign Portfolio Investors (FPIs) to overseas investors who wish to invest in Indian securities without directly registering with SEBI. The FPI holds the underlying Indian securities on behalf of the overseas investor, and the P-Note represents their beneficial ownership.

Why other options are incorrect:
• Certificate of Deposit is a short-term debt instrument issued by banks to mobilize deposits, not related to stock market participation.
• Commercial Paper is an unsecured short-term debt instrument issued by corporations to meet working capital needs, not for foreign portfolio investment.
• Promissory Note is a written promise to pay a specified sum of money at a future date, unrelated to stock market investment mechanisms.

📝 Short Notes: Participatory Notes (P-Notes)

• Definition: Offshore derivative instruments issued by registered FPIs to overseas investors for investing in Indian securities without direct SEBI registration.
• Regulatory Body: Securities and Exchange Board of India (SEBI) regulates P-Notes through FPI regulations.
• Advantages: Easier market access for foreign investors, reduced compliance burden, and anonymity for investors.
• Concerns: Potential for round-tripping of funds, lack of transparency regarding ultimate beneficiaries, and money laundering risks.
• SEBI Regulations: SEBI has tightened P-Note norms over time, requiring FPIs to conduct proper KYC of P-Note subscribers and restricting certain derivative structures.
• Market Impact: P-Notes constitute a significant portion of FPI investments in India, though their share has declined due to stricter regulations.
