One index view, three instruments
Lessons 13–17 compare the vehicles that can hold the same view of the same index. (A gold contract is a view on gold — it cannot hold an index view at all, so it is not a row in this table.)
| Dimension | Shares — fully paid, long | Index future (E-mini S&P 500, ES) | Bought index call |
|---|---|---|---|
| What you hold | A fractional interest in the corporation itself; the corporation owns the assets | A contract on the index’s level at a future date — no ownership | A right to buy at the strike until expiration — no ownership unless exercised |
| Leverage | None built in, bought with your own cash | Built in: the multiplier is $50 per index point; at an index of 5,000, one contract is $250,000 of notional exposure | Built in: one contract covers 100 shares; a $5.00 premium is $500 paid per contract |
| Capital down | The full purchase price | Margin — a deposit, not the maximum loss | The premium, paid up front |
| Expiration | None — no clock | Yes — settle in cash or roll before it | Yes — the right dies at expiration |
| Liquidity | Deep, tight spreads in large index names and funds | Deep, nearly around the clock in the major index futures | Varies by strike and date; thin or far strikes carry wide spreads and hard exits |
| Monitoring | Least — the vehicle that waits | Most — daily settlement and expiry dates to mind | The clock runs: time decay is slow at first and faster as expiration nears; decay is not constant |
| Worst case | Loss capped at the stake — only when fully paid, unleveraged and long; borrow to buy or sell short and the cap disappears | Losses can run past the deposit; each day’s move settles in cash | The premium paid — for the option itself. Exercise is the one door out of the cap: a $100 strike takes $10,000 per contract and leaves you holding shares |
Reaching a commodity instead: four routes
| Route | What it is, in one line |
|---|---|
| Physical holdings | You own the good itself — with storage, insurance and dealer spreads; practical for gold, impractical for oil or grain |
| Futures | The purest exposure to the good’s price — deposit, daily settlement, expiry and roll, and the most attention of the four |
| Commodity funds | Bought like a share, with fees; because funds roll futures, returns can drift from the good’s own price |
| Producer equities | Ownership of a business: the commodity price drives earnings, but costs, debts and management also drive the shares — they can fall in a year the good rose |
Prices in this folder rest on physical facts and expectations of them: an announcement about future supply can move the price the day it lands, before a single barrel changes.
