Definition

A mutual fund (or open-end fund) is a pooled investment vehicle that collects money from many investors and invests it in a diversified portfolio of stocks. "Open-end" means the fund issues and redeems shares on demand based on its Net Asset Value (NAV).

NAV = (Total Value of Portfolio – Liabilities) / Shares Outstanding

Mechanism

Investors buy or redeem shares directly from the fund company, not from other investors. Shares are priced once per day at NAV, which is calculated after the market closes. A fund manager actively manages the portfolio based on a specific investment mandate.

Example

An investor buys $10,000 worth of the Fidelity Blue Chip Growth Fund. They receive shares at that day's closing NAV (e.g., $50/share = 200 shares). If the NAV rises to $55, their investment value becomes $11,000.

Index Funds

These are passive funds that aim to replicate the performance of a market index, like the S&P 500. They are low-cost, have low turnover, and their NAV is calculated daily like a mutual fund. An example is the Vanguard 500 Index Fund.

Exchange-Traded Funds (ETFs)

ETFs are typically index-tracking funds that are traded on stock exchanges, just like individual stocks. Unlike mutual funds, ETFs can be bought and sold intraday at market prices.

ETF Creation/Redemption Mechanism

Authorized Participants (APs) keep the ETF's market price aligned with its NAV through an arbitrage process:

  1. Creation: APs deliver a basket of the underlying securities to the ETF issuer in exchange for new ETF shares.
  2. Redemption: APs return ETF shares to the issuer in exchange for the underlying securities.

If an ETF trades above its NAV, APs will sell the ETF and buy the underlying stocks, pushing the ETF price down. If it trades below NAV, they do the opposite.

Tracking Error: This is the small difference between an ETF's returns and its underlying index's returns, caused by fees, cash drag, or sampling methods.

Definition

Hedge funds are private, actively managed investment vehicles for accredited or institutional investors. They aim for absolute returns using flexible strategies like leverage, short selling, and derivatives. They typically charge "2 and 20" fees (2% management fee, 20% performance fee).

Key Hedge Fund Strategies

StrategyDescriptionExample
Long/Short EquityGo long undervalued stocks and short overvalued ones.Long Apple, short Dell.
Market NeutralBalance long and short positions to remove market beta.+$100M in long positions, –$100M in short positions.
Event DrivenTrade corporate events like mergers or spinoffs.Long the target company, short the acquirer in a merger.
ActivistTake significant stakes in companies to push for strategic changes.Elliott Management's involvement in Twitter.
QuantitativeUse algorithmic and statistical models for trading.Renaissance Technologies.

Definition

These are large, long-term institutional investors managing public or corporate retirement assets (pension funds) or state reserves (SWFs). They focus on capital preservation, steady growth, and income over extremely long horizons.

Examples

Role of Equity

Equities serve as the primary long-term growth driver in their asset allocation, often making up 40–70% of the portfolio.

Definition

Private equity involves investing in non-public companies or taking public companies private with the goal of improving operations and selling them for a profit later. These are long-term (5–10 years), illiquid, high-risk, and high-return investments.

Types of PE Investments

TypeDescriptionExample
Venture Capital (VC)Investing in early-stage, high-growth startups.Sequoia investing in Stripe.
Growth EquityProviding capital for mature firms that are scaling rapidly.Tiger Global investing in Flipkart.
Buyouts / LBOsAcquiring a controlling stake in a company, often using significant debt.KKR buying Boots Alliance.
Mezzanine FinancingHybrid debt-equity financing for expansion or pre-IPO funding.Convertible debt + equity warrants.

Definition

Equity strategies that focus on generating steady income through dividends or option premiums, rather than just capital appreciation.

Types of Income Strategies

StrategyDescriptionExample
Dividend Growth FundsFocus on companies that consistently increase their dividends.Procter & Gamble, Johnson & Johnson.
High-Dividend FundsTarget the highest-yielding stocks available.Utility and REIT ETFs.
Covered Call ETFsEnhance income by systematically selling call options on the fund's holdings.Global X NASDAQ 100 Covered Call ETF (QYLD).

Definition

Smart beta and factor investing systematically tilt portfolios toward certain characteristics (factors) that have been shown to deliver excess returns over time. It is a rules-based, quantitative approach.

Common Factors

FactorDescription
ValueCheap stocks (low P/E, P/B) tend to outperform.
MomentumStocks that have been trending higher tend to continue rising.
QualityCompanies with high ROE and stable earnings tend to perform well.
SizeSmall-cap stocks have historically outperformed large-cap stocks over time.
Low VolatilityLower-beta stocks tend to outperform on a risk-adjusted basis.

Definition

Quant strategies use data science, statistics, and algorithms to identify and exploit market inefficiencies to generate alpha.

Key Quant Approaches

StrategyDescriptionExample
Statistical ArbitrageExploits short-term mispricings between correlated stocks.Pair trading Coke vs. Pepsi.
Factor ModelsUses multi-factor models (e.g., Fama-French) to forecast returns.Overweighting value, underweighting growth.
Pairs TradingLong one stock and short a related one based on mean reversion.Long Ford, short GM when their price ratio deviates.
ML-Driven AlphaUses machine learning to identify predictive signals from vast datasets.Using NLP on news sentiment to trade earnings.

Understand the ETF creation/redemption process, as it's a favorite interview question. Be ready to explain the key differences between hedge funds, mutual funds, and private equity. For factor investing, connect it to academic theory like the Fama-French factors.
