Wetin Be Call Options? See How Dem Dey Work

A call option na right to buy 100 shares of a stock for fixed strike price on or before set date. You pay premium for that right, and you no get obligation to use am. If stock climb pass your fixed price, the call gain value. If e no ever reach there, the maximum wey you fit lose na the premium wey you pay.

The clearest way to learn call na to watch one real contract move. This post follow one SPY call: the $740 strike wey expire June 18, 2026, from May 1 reach the final week. SPY na the ETF wey track S&P 500, so this call na bet say the index go rise pass 740 before that date.

The four things wey define call

Every call get four terms:

• Strike price: the fixed price wey you fit use buy the shares. Our own na $740.
• Expiration: the last day wey the right dey valid. Our own na June 18, 2026.
• Premium: wetin the call cost, quoted per share. Quote of $7.22 cost $722 for one contract.
• Multiplier: one contract control 100 shares. Quotes dey per share, so multiply by 100 to get the real dollar figure.

See the full life of that one call, indexed so both the stock and option start at 100 on May 1. Watch how small SPY movement be compared with how far the call travel:

WITH d AS (
  SELECT date, avg(underlying_close) AS spy, avg(option_close) AS call
  FROM global_markets.options_greeks
  WHERE ticker = 'O:SPY260618C00740000' AND date BETWEEN '2026-05-01' AND '2026-06-15' AND implied_volatility > 0.02
  GROUP BY date
)
SELECT date,
       round(100 * spy / first_value(spy) OVER (ORDER BY date), 0) AS spy_indexed,
       round(100 * call / first_value(call) OVER (ORDER BY date), 0) AS call_indexed
FROM d
ORDER BY date

That one contract carry 31 trading sessions of history. The stock line almost flat; the call line dey whip from far above where e start to well below am and back. Same underlying, but the ride dey very different.

Intrinsic value versus time value

Call price split into two parts. Intrinsic value na wetin the right worth if you exercise am now: stock price minus strike, or zero when stock dey below strike. Time value na everything else wey you pay, the premium for the chance say stock go climb further before expiry.

On May 1, SPY at $720 dey below the $740 strike, so the call intrinsic value na $0. All the $7.22 of the price na time value: pure hope, with no floor. By June 2, SPY don rise to $759.63, roughly $20 above the strike, and intrinsic value don grow to $19.63 of the $23.5 price. Time value don reduce to $3.87.

SELECT date,
       round(option_close, 2) AS call_price,
       round(greatest(underlying_close - 740, 0), 2) AS intrinsic_value,
       round(option_close - greatest(underlying_close - 740, 0), 2) AS time_value
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260618C00740000'
  AND date IN ('2026-05-01', '2026-05-14', '2026-06-02', '2026-06-10', '2026-06-15')
  AND implied_volatility > 0.02
ORDER BY date

As June 18 dey near, time value dey drain toward zero: the closer expiry dey, the less time remain for another move. By June 15, three sessions before the end, the $15.41 call get only $1.5 time value. That daily bleed na time decay, one of the option greeks, and when option dey expire determine how fast e bite.

In, at, and out of the money

Traders describe call based on where the stock dey compared with the strike:

• Out of the money: stock dey below strike. Intrinsic value na zero; the price na all time value.
• At the money: stock dey roughly at the strike.
• In the money: stock dey above strike. The call get real intrinsic value.

Our call start out of the money, with SPY at $720 against $740 strike. E enter the money when SPY rally pass 740, then fall back out on June 10. Its $3.17 price become pure time value again, with $0 intrinsic value. Where call dey on this scale affect how e behave: out-of-the-money call nearly be all bet, while in-the-money call dey move more like the stock itself. That sensitivity to the stock na option delta.

Why calls dey magnify moves (leverage)

Call control 100 shares for only part of their price, so its percentage swings dey much bigger than the stock own. The contract wey we follow show this clearly.

WITH m1 AS (SELECT underlying_close AS spy, option_close AS call FROM global_markets.options_greeks WHERE ticker = 'O:SPY260618C00740000' AND date = '2026-05-01'),
     m2 AS (SELECT underlying_close AS spy, option_close AS call FROM global_markets.options_greeks WHERE ticker = 'O:SPY260618C00740000' AND date = '2026-06-02')
SELECT instrument, start_price, end_price, pct_change FROM (
  SELECT 'SPY stock' AS instrument,
         round((SELECT spy FROM m1), 2) AS start_price,
         round((SELECT spy FROM m2), 2) AS end_price,
         round(100 * ((SELECT spy FROM m2) - (SELECT spy FROM m1)) / (SELECT spy FROM m1), 1) AS pct_change,
         1 AS o
  UNION ALL
  SELECT 'SPY 740 call',
         round((SELECT call FROM m1), 2),
         round((SELECT call FROM m2), 2),
         round(100 * ((SELECT call FROM m2) - (SELECT call FROM m1)) / (SELECT call FROM m1), 1),
         2 AS o
) ORDER BY o

Between May 1 and June 2, SPY rise 5.5%, from $720 to $759.63. For that same period, the call rise 225.5%, from $7.22 to $23.5. Small move for the stock turn into very big move for the option.

That multiplier dey work for both directions. When SPY fall through early June, the call give back almost everything, falling to $3.17 by June 10. Leverage amplify losses at the same rate e amplify gains, and out-of-the-money call fit expire at zero while the stock only fall small. The amplification get tighter as expiry near and volatility rise. Na the area of 0DTE options and implied volatility.
