# Futures versus ETFs **FUT-13 · Equity Index Futures · Core** **Lesson question:** Which instrument fits the exposure and workflow? Original fictional examples; educational writing, not live market data, orders or production approval. ## By the end - Explain the mechanism in the lesson question. - Reproduce the worked comparison and recognize its failure case. **Prerequisites:** FUT-01 Futures and index ETFs can express similar broad views through different structures. Futures have expiries, multipliers and settlement cash flows. ETFs are shares with fund expenses, distributions and account-specific financing. Choose by total economics and operational needs, not which displayed quote looks cheaper. ## Understand the mechanism Equal notional is only an initial comparison. Tracking, index composition, trading windows, funding, shorting, fees and tax treatment can differ. No universal tax or regulatory advantage is asserted here. A smaller futures margin requirement changes capital posted, not gross exposure or maximum loss. ## Walk through the process Translate both alternatives into the same dollar exposure. Compare execution at the intended size and time, the holding horizon and ongoing administration. For hedging, assess the actual economic match rather than assuming any broad-index product offsets any stock portfolio. ## Operational boundary All prices, portfolio values and account balances are fictional. Real contract calendars, broker requirements and available liquidity must be checked for the instrument actually traded. The example's mathematical hedge or payoff is not an execution guarantee. ## A worked example A fictional 100,000 exposure can be approximated with four micro contracts if each is 5,000×5=25,000 notional. An ETF at 500 would require 200 shares for the same gross value. Those alternatives still have different cash, distribution and expiry workflows. The graph scales micro count, not a recommendation favoring one instrument. ## Graph: Futures versus ETFs—worked comparison **Horizontal:** Micro contracts **Vertical:** Gross notional (USD) Fictional data from the written example. The chart organizes the comparison; its shape is not a forecast. Complete numerical data are embedded in `scripts/equity-futures/FUT-13.js` and displayed as an accessible table in the HTML lesson. ## What would invalidate the reading? Selecting futures solely from their smaller deposit can introduce unintended leverage. Selecting an ETF solely because it does not expire can ignore financing or tracking costs. ## Check your understanding ### How many 25,000-notional micros match 100,000? **Answer:** Four. **Why:** Notional matching is not a complete total-cost comparison. ### What is the critical failure to avoid? **Answer:** Selecting futures solely from their smaller deposit can introduce unintended leverage. Selecting an ETF solely because it does not expire can ignore financing or tracking costs. **Why:** Explain this risk before treating the example as a decision rule. A correct calculation does not guarantee a favorable market outcome. **Critical risk check.** ## Takeaway Return to the question: Which instrument fits the exposure and workflow? State the observed facts, the assumptions and the failure condition separately. ## References and provenance The cited references support definitions and conventions.
