Deep Dive: The “Big Three” Topics
To pass the IISI exam, you must secure strong marks in the three most heavily weighted areas:
1. Equities and Bonds (28% combined)
These two chapters form the bedrock of the qualification.
- For Equities, you must understand the different types of corporate actions (rights issues, bonus issues), the rights of ordinary vs. preference shareholders, and how equity markets operate.
- For Bonds, focus heavily on the relationship between price and yield. Understand the difference between government bonds and corporate bonds, and how credit ratings impact bond pricing.
2. Investment Funds (12%)
You will be tested on the structural differences between open-ended and closed-ended funds. Ensure you know the definitions and operational mechanics of Unit Trusts, OEICs, Investment Trusts, and Exchange Traded Funds (ETFs).
3. Financial Services Regulation (14%)
This chapter is dense with terminology. Focus on the core principles of authorization, client money rules, money laundering stages, and the definition of insider dealing and market abuse.
