💰Finance Unit 12 – Derivatives and Risk Management

What Are Derivatives?

• Financial instruments that derive their value from an underlying asset, such as stocks, bonds, commodities, or currencies
• Enable investors to hedge against potential losses or speculate on price movements without owning the underlying asset
• Contracts between two parties that specify the terms of the transaction, including the price, quantity, and settlement date
• Leverage allows investors to control a larger position with a smaller initial investment, amplifying potential gains and losses
• Derivatives can be traded on regulated exchanges (futures, options) or over-the-counter (swaps, forwards)
• Facilitate risk transfer from one party to another, enabling more efficient allocation of capital
• Provide liquidity to financial markets by allowing investors to easily enter and exit positions

Types of Derivatives

• Futures contracts obligate the buyer to purchase an asset at a predetermined price on a specific future date
  • Standardized contracts traded on exchanges (Chicago Mercantile Exchange)
  • Used for hedging and speculation in commodities, currencies, and financial instruments
• Options give the buyer the right, but not the obligation, to buy (call) or sell (put) an asset at a predetermined price (strike price) on or before a specific date (expiration)
  • Traded on exchanges (Chicago Board Options Exchange) or over-the-counter
  • Buyers pay a premium for the right to exercise the option
• Swaps involve the exchange of cash flows between two parties based on a notional principal amount
  • Interest rate swaps exchange fixed and floating interest payments
  • Currency swaps exchange principal and interest payments in different currencies
• Forwards are customized contracts between two parties to buy or sell an asset at a specific price on a future date
  • Traded over-the-counter and not standardized like futures
  • Often used for hedging currency or commodity price risk
• Credit derivatives, such as credit default swaps (CDS), transfer credit risk from one party to another
  • CDS buyer makes periodic payments to the seller in exchange for protection against a credit event (default, bankruptcy)
• Exotic derivatives are complex instruments tailored to specific investor needs or market conditions
  • Barrier options, lookback options, and Asian options
  • Structured products combine derivatives with other financial instruments

Pricing and Valuation

• Derivative pricing models use mathematical formulas to determine the theoretical value of an instrument based on various inputs
• Black-Scholes model is widely used for pricing European-style options
  • Inputs include the current price of the underlying asset, strike price, time to expiration, risk-free interest rate, and implied volatility
• Binomial option pricing model uses a discrete-time framework to value American-style options
  • Constructs a tree of possible price paths for the underlying asset
• Monte Carlo simulation generates multiple random price paths for the underlying asset to estimate the derivative's value
• Implied volatility reflects the market's expectation of future price fluctuations and is a key input in pricing models
• Greeks (delta, gamma, theta, vega, rho) measure the sensitivity of an option's price to changes in various inputs
  • Delta represents the change in option price for a given change in the underlying asset price
  • Gamma measures the rate of change of delta
• Pricing models rely on assumptions, such as constant volatility and no transaction costs, which may not hold in real-world markets
• Mark-to-market accounting requires derivatives to be valued at their current market price, which can lead to significant fluctuations in reported profits and losses

Trading Strategies

• Hedging involves using derivatives to offset the risk of an existing position in the underlying asset
  • A company can use currency forwards to lock in a favorable exchange rate for future foreign currency transactions
  • An investor holding a stock portfolio can purchase put options to protect against potential market downturns
• Speculation seeks to profit from predicted price movements in the underlying asset
  • Traders can buy call options if they believe the price of the underlying asset will rise or buy put options if they expect the price to fall
  • Futures contracts allow speculators to take long or short positions in various markets (commodities, currencies, indices)
• Arbitrage exploits price discrepancies between related assets or markets to generate risk-free profits
  • If the same asset is trading at different prices on two exchanges, an arbitrageur can buy the cheaper one and sell the more expensive one
  • Index arbitrage involves trading futures contracts against the underlying basket of stocks
• Spread trading involves simultaneously buying and selling related derivatives to profit from changes in their relative prices
  • Calendar spreads trade options or futures with different expiration dates
  • Butterfly spreads combine bull and bear spreads to profit from low volatility
• Volatility trading strategies aim to profit from changes in implied volatility rather than the direction of the underlying asset price
  • Long straddle involves buying both a call and a put option with the same strike price and expiration, profiting from large price moves in either direction
  • Short strangles sell out-of-the-money call and put options, profiting from stable prices and declining implied volatility

Risk Management Techniques

• Position sizing determines the appropriate amount of capital to allocate to each trade based on the investor's risk tolerance and account size
  • Kelly criterion maximizes long-term growth by sizing positions based on the expected value and probability of success
• Diversification spreads risk across multiple asset classes, sectors, and geographies to reduce the impact of any single position
• Stop-loss orders automatically close a position when the price reaches a predetermined level, limiting potential losses
  • Trailing stops adjust the stop-loss level as the price moves in the investor's favor, locking in profits
• Value at Risk (VaR) estimates the maximum potential loss for a given portfolio over a specific time horizon and confidence level
  • Historical VaR uses past price data to estimate future risk
  • Monte Carlo VaR simulates multiple price paths based on assumed probability distributions
• Stress testing evaluates a portfolio's performance under extreme market conditions or hypothetical scenarios
  • Helps identify potential vulnerabilities and inform risk mitigation strategies
• Counterparty risk assessment evaluates the creditworthiness and stability of trading partners
  • Credit ratings, financial statements, and market indicators (CDS spreads) provide insight into counterparty risk
• Margin requirements ensure that investors maintain sufficient collateral to cover potential losses on leveraged positions
  • Exchanges and brokers set initial and maintenance margin levels based on the volatility and risk of the underlying asset
• Risk governance frameworks establish clear policies, procedures, and oversight for managing derivatives-related risks
  • Risk committees, limits, and reporting requirements ensure that risks are identified, measured, and controlled

Market Participants

• Hedgers use derivatives to manage exposure to various financial risks, such as price fluctuations, interest rate changes, or currency movements
  • Commodity producers (farmers, mining companies) can lock in future prices using futures contracts
  • Corporations can use interest rate swaps to convert floating-rate debt into fixed-rate obligations
• Speculators aim to profit from predicted price movements in the underlying assets
  • Hedge funds employ sophisticated strategies to exploit market inefficiencies and generate high returns
  • Day traders use technical analysis and short-term price fluctuations to make rapid trades
• Arbitrageurs seek to profit from price discrepancies between related assets or markets
  • High-frequency trading firms use algorithms to identify and exploit fleeting arbitrage opportunities
• Market makers provide liquidity by continuously quoting bid and ask prices for derivatives
  • Banks and specialized trading firms act as market makers in various derivative markets
• Institutional investors, such as pension funds and insurance companies, use derivatives for hedging, yield enhancement, and portfolio diversification
• Retail investors can access derivatives through brokers or packaged products (ETFs, structured notes) to gain exposure to specific strategies or markets
• Clearing houses act as intermediaries between buyers and sellers, reducing counterparty risk by guaranteeing the performance of the contracts
  • Major clearing houses include the Chicago Mercantile Exchange (CME) and the Intercontinental Exchange (ICE)
• Regulators, such as the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC), oversee derivatives markets to ensure fair and transparent trading practices

Regulatory Environment

• Dodd-Frank Wall Street Reform and Consumer Protection Act (2010) introduced sweeping changes to the U.S. financial system in response to the 2008 financial crisis
  • Mandated central clearing for most standardized over-the-counter derivatives
  • Established the Volcker Rule, prohibiting banks from engaging in proprietary trading and limiting their investments in hedge funds and private equity funds
• European Market Infrastructure Regulation (EMIR) and Markets in Financial Instruments Directive (MiFID) II regulate derivatives trading in the European Union
  • Require central clearing, trade reporting, and improved transparency for over-the-counter derivatives
• Basel III capital and liquidity standards require banks to hold more capital against their derivatives exposures and improve their risk management practices
• Margin requirements for non-centrally cleared derivatives mandate the exchange of initial and variation margin between counterparties to reduce systemic risk
• Position limits restrict the number of contracts a single entity can hold to prevent excessive speculation and market manipulation
• Swap execution facilities (SEFs) are regulated trading platforms that aim to increase transparency and competition in the swaps market
• Reporting requirements oblige market participants to disclose their derivatives transactions to trade repositories, enabling regulators to monitor systemic risk
• Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations require financial institutions to verify the identity of their clients and prevent illicit activities

Real-World Applications
