LEAPS & stock replacement

Definition

LEAPS are exchange-listed options with expirations out to roughly three years. STOCK REPLACEMENT is their signature use: substituting a deep in-the-money LEAPS call (delta 0.80+) for a stock position — controlling similar upside exposure for a fraction of the capital, with loss capped at the premium paid. The structure converts a stock thesis into a defined-risk, capital-efficient position at the cost of time decay, dividend forfeiture, and a hard expiry date on a thesis that may not respect calendars.

How it works / structure

• The construction (engine-parameterizable): buy a call 12-30 months out, deep ITM (delta 0.75-0.90 — greek-delta selects the stock-likeness); capital outlay ≈ intrinsic + modest time value; the freed capital is the structure’s point (and its temptation — see failure modes).
• The economics vs stock: pays time value (greek-theta — small per day at long tenor and deep moneyness, but nonzero); forfeits dividends (priced into calls — opt-dividend-effects); caps loss at premium (the stock can lose more); no margin interest (the embedded financing is the time value — comparing it to margin rates is the honest cost comparison); early-exercise/assignment doesn’t apply to the holder (American-style long positions exercise at choice — acct-assignment-tax for tax shape).
• Variants: the poor-man’s covered call (LEAPS long
  • short near-dated calls against it — strategy-covered-call economics on option collateral, a diagonal — strategy-diagonal-spread family); moderate-delta LEAPS (0.60) as leveraged directional theses with more convexity and more decay.
• Rolling discipline: LEAPS held past ~6-9 months to expiry enter accelerating theta — the documented practice is rolling out while time value is still cheap to replace (opt-term-structure pricing of the roll).

When it applies

Long single-name theses where capital efficiency matters (the freed capital funding hedges or diversification — not more of the same exposure); defined-risk versions of strategy-buy-and-hold convictions in volatile names (the premium cap IS the stop that gaps can’t jump); low-IV entry windows (long options bought cheap — IV percentile as an entry gate).

Risk profile & failure modes

• The leverage temptation (the signature failure): replacing $50k of stock with a $15k LEAPS and then buying MORE LEAPS with the difference converts a defined-risk structure into concentrated leverage — position sizing must count exposure (delta × notional), not premium spent.
• Thesis-calendar mismatch: the stock can be right after the option expires — expiry converts “eventually” theses into total losses; tenor must exceed the thesis’s honest timeline with buffer.
• IV entry risk: LEAPS bought at high IV suffer vega losses even as the stock cooperates (greek-vega at long tenor is large) — the entry-IV gate is structural, not cosmetic.
• Liquidity/spread cost: long-dated books are wide; entering and rolling pays real friction — limit-order discipline (ms-order-types) and roll-count minimization matter.

Evidence & limits

Contract mechanics are OCC/Cboe-documented; the cost-vs-margin financing comparison is arithmetic; no claim is made that stock replacement outperforms stock — it re-shapes the exposure (capped loss, paid carry, dated). The KB treats it as a structure choice governed by the same falsifiable thesis the stock position would carry.

Falsifiable-thesis examples

Illustrations only, not signals:

• “A 0.85-delta 24-month LEAPS position replicates the stock’s return within 3% per year less its measured time-value cost across the replay universe (stock-likeness check)” — falsified by the paired replay.
• “Rolling at 9 months to expiry costs less time value than holding into the final 6 months across the historical windows (roll-discipline check)” — falsified by the roll-ledger comparison.
