Deep ITM LEAPS As Stock Replacement Strategy Explained

A deep in-the-money LEAPS call na one long-dated option wey dey trade well above im strike price, and active traders dey hold am as stock replacement: one single contract dey stand for 100 shares at small fraction of the cash. LEAPS (Long-term Equity AnticiPation Security) just mean say option get pass one year before e go expire. "Deep in the money" mean say the strike sit far below the current stock price, so the option dey built mostly of intrinsic value (real, dollar-for-dollar stock value) and e carry high delta. This post dey follow one real SPY LEAPS call through im deep-ITM life to show wetin the swap buy and wetin e cost.

The contract na SPY $600 call option wey go expire January 16, 2026. We pick am for early June 2025, with SPY back above $600 and the call already in the money, and we dey follow am toward expiry.

Wetin stock replacement mean

To own 100 shares of one S&P 500 ETF na to get one dollar of gain for every dollar the fund rise. One deep-ITM call for the same fund dey do nearly the same thing for far less money down. The link na delta: the amount the option go move per $1 move for the stock. One share get delta of exactly 1. When call delta sit near 0.9, e dey capture about 90 cents of every dollar the stock add while e dey tie up small slice of the cash wey one share position need. That gap between exposure and cash na the whole appeal.

Delta dey climb toward 1

As SPY push further above the $600 strike for the second half of 2025, the call delta climb steadily toward one share own:

SELECT toStartOfWeek(date, 1) AS week,
       round(avg(delta), 3) AS delta
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260116C00600000' AND date BETWEEN '2025-06-02' AND '2026-01-13' AND implied_volatility > 0.02
GROUP BY week ORDER BY week

Delta open the window for 0.586 for early June and e reach 0.962 by mid-January. Delta of 0.962 mean say the LEAPS move almost exactly like the stock, near enough one-for-one say holder go feel the same daily profit and loss wey shareholder go feel per dollar of SPY. The full set of sensitivities wey dey behind that number na the option greeks.

The capital efficiency

The point of the swap na the cash wey e free. Watch the same inputs for three deep in-the-money dates:

SELECT date,
       round(avg(underlying_close), 2) AS spy_close,
       round(avg(underlying_close) * 100, 0) AS shares_cost,
       round(avg(option_close), 2) AS leaps_price,
       round(avg(option_close) * 100, 0) AS leaps_cost,
       round(avg(underlying_close) / avg(option_close), 1) AS leverage_x,
       round(avg(delta), 3) AS delta
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260116C00600000' AND date IN ('2025-07-01', '2025-10-09', '2025-12-01') AND implied_volatility > 0.02
GROUP BY date ORDER BY date

For October, with SPY closing for $671.96, one hundred shares cost about $67,200. The LEAPS trade for $82.03 per share, so one single contract for the same 100 shares run about $8,200: roughly 8.2 times less capital for position wey dey carry delta 0.897. Trader fit hold the SPY exposure and park the other ~$59,000 for cash or Treasuries. The leverage multiple actually shrink as the call dey go deeper, from 12.7 times for July go reach 8 times for December. Deeper call cost more, so e command less leverage per dollar even as im delta dey rise.

Leverage, indexed

Index SPY and the LEAPS to 100 for the start and the amplification dey clear:

SELECT week,
       round(spy / first_value(spy) OVER w * 100, 1) AS spy_index,
       round(leaps / first_value(leaps) OVER w * 100, 1) AS leaps_index
FROM (
  SELECT toStartOfWeek(date, 1) AS week,
         avg(underlying_close) AS spy,
         avg(option_close) AS leaps
  FROM global_markets.options_greeks
  WHERE ticker = 'O:SPY260116C00600000' AND date BETWEEN '2025-06-02' AND '2026-01-13' AND implied_volatility > 0.02
  GROUP BY week
)
WINDOW w AS (ORDER BY week)
ORDER BY week

SPY finish the window near 116.6 for that scale, mid-teens percentage gain. The LEAPS, wey dem index the same way, reach 265.8, pass double. One contract turn mid-teens move for the fund go triple-digit percentage gain for the premium. This na the same leverage wey the low cash outlay dey imply, dem read am as return instead of price.

Why the decay dey small

The normal knock for options na time decay. Deep in the money, that worry mostly dey fall away. Almost all of deep-ITM premium na intrinsic value, wey no dey decay; only the thin extrinsic (time) portion go erode as expiry dey near.

SELECT toStartOfMonth(date) AS month,
       round(avg((option_close - greatest(underlying_close - 600, 0)) / option_close) * 100, 1) AS extrinsic_pct,
       round(avg(theta), 3) AS theta
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260116C00600000' AND date BETWEEN '2025-06-02' AND '2026-01-13' AND implied_volatility > 0.02
GROUP BY month ORDER BY month

For early June, with SPY sit near the $600 strike, 92.7% of the premium na time value. By December, deep in the money, that one don thin to 3.6%: only few dollars of the $84.49 December premium na decayable time value. Theta, the dollars of value wey dem lose per day, run near -0.106 through most of the hold and e only steepen to -0.441 for the final month as the last of the time value drain. Stock-replacement trader go close or roll the position well before that final-weeks ramp, so dem go sidestep the steep decay entirely. How that curve behave over option life na im own topic: how the greeks change over time.

The trade-offs

The swap no free. Three costs dey ride with am:

1. No dividend. Shareholder dey collect SPY quarterly distribution; call holder no dey collect. Over long hold, that forgone yield na real money.
2. One fixed expiry. Stock no dey expire; the LEAPS dey expire. To keep the exposure alive mean say you go roll into later-dated contract before the option expires, and you go pay fresh spread each time.
3. Wider spread. Options cost more to enter and exit than the underlying ETF, and one mispriced roll go chop the capital wey the strategy save.

Leverage also cut both ways. The low outlay cap the dollar loss for the premium, yet one sharp drop for SPY go shrink the call faster for percentage terms than the stock move. The same delta wey reward the upside go sharpen the downside. The strategy fit trader wey want defined-risk, capital-efficient exposure and go actively manage the roll, no be set-and-forget shareholder. The bearish mirror of the idea dey use puts instead: see buying and selling put options.
