What you'll learn
- Index Funds as Research Objects. You've just selected a fund tracking the S&P 500.
- Market Efficiency and Strategy. The Grossman-Stiglitz paradox cuts straight to the tension: if markets were perfectly efficient, no one would pay to gather information, so prices would stop being efficient.
Questions this course answers
What is the outermost layer of an index fund?
The legal wrapper is the outermost layer, which is a 1940 Act mutual fund, a '40 Act ETF, or an offshore SICAV.
How does synthetic replication work?
Synthetic replication transfers index exposure to a counterparty via total-return swaps.
Why is rules-based design epistemically deliberate?
Rules-based design makes the fund's behavior falsifiable and auditable, which allows performance attribution and factor decomposition to be tractable research problems.
What does the Grossman-Stiglitz paradox state?
The Grossman-Stiglitz paradox highlights that if markets were perfectly efficient, no one would pay to gather information, so prices would stop being efficient.
