Multiplier, margin, and stop discipline on cash-settled index minis

A smaller cash-settled index future

Smaller-multiplier cash-settled index futures were introduced so a retail-sized account could hold index exposure at a lower notional and lower outlay than a full-size contract.

Editorial: that listing is a mini-index-contract, a reduced-multiplier, electronically traded index future that lowers per-contract outlay and notional versus a full-size contract.

Contract-multiplier and notional-value

With a five-dollar multiplier, a quoted level of 8500 implied a 42500-dollar contract value.

Editorial: notional-value is the quoted futures level multiplied by the contract-multiplier. The contract-multiplier is the dollar amount gained or lost for each one-point move in the quoted index future.

Initial-margin and the equity hit

An initial margin of 2700 dollars per contract left most of that notional unfunded, so a given index move changed account equity by a much larger percentage than it changed the index.

An adverse move on a leveraged contract can produce a loss larger than the initial margin deposit.

Editorial: initial-margin is the deposit required to open one contract, a fraction of full notional-value. Leverage-control means keeping notional exposure and posted margin inside a planned equity impact before entry and for as long as the position is open.

Stop-loss as required discipline

A 100-point stop on the five-dollar contract maps to a 500-dollar maximum loss because each point is worth five dollars.

In the worked adverse-move example, that 500-dollar stop loss was about 1.19 percent of unlevered notional and about 18.5 percent of the 2700-dollar margin.

Applying stops was treated as required discipline for leveraged index futures, not an optional overlay, because margin does not cap the loss.

Editorial: a stop-loss is a pre-committed exit distance, in index points, that converts to a bounded dollar loss through the contract multiplier.

Basis, live terms, and path size

The cash index and the mini future moved almost in step, with a small premium explained by financing cost versus dividends on the basket.

Editorial: that usual premium is the cash-futures-basis, the premium of the future over the cash index linked to financing cost versus dividends on the underlying basket.

Live contract terms were listed as items to check because they can change: multiplier, tick value, listed months, cash settlement, electronic hours, and successive 10, 20, and 30 percent daily limits.

A 30-name industrial index was argued to be less likely than a single glamour stock to move 75 to 90 percent in a year, which is a contract-selection point about path size rather than a safety guarantee.

Editorial: futures-contract-selection means choosing among index products by multiplier, margin, settlement, limits, and how closely the contract tracks the cash basket.
