Question restatement: Today, SPY is at $285. A put option on SPY with a strike of $250 that matures tomorrow has a price around $0.01. You invest the entire capital of $1,000 to buy that put. The portfolio's value for the next day is to be filled in as a number.

Step-by-step analysis:
- First, determine how many put contracts you can buy with $1,000 given the option price. The option price is $0.01 per share, and each standard option contract covers 100 shares. So the cost per contract is $0.01 × 100 = $1. Therefore, with $1,000, you can buy 1,000 contracts (since $1,000 ÷ $1 per contract = 1,000 contracts).
- Next, evaluate the intrinsic value of the put at the next day’s price. A put with strike 250 has intrinsic value only if SPY’s price falls below 250. If SPY stays at or above 250, the put expires worthless at maturity (intrinsic value = max(0, 250 − S_T) = 0 when S_T ≥ 250).
- In this scenario, the given current price of SPY is 285. Since 285 is well above the strike of 250, and the option matures tomorrow, the likelihood (based on the information provided) is that SPY remains above 250 or ends above 250, leaving the put with zero intrinsic value at expiration.
- Therefore, the option’s value the next day would be 0 per contract, and the entire 1,000-contract position would be worth $0 at expiration (assuming no extrinsic value remains or there is no remaining time value, which is typically minimal at expiration).
- Important caveat: If SPY tomorrow ends with a price below 250, the puts would have positive intrinsic value. The value would then be (250 − S_T) per share, times 100 shares per contract, multiplied by 1,000 contracts. For example, if SPY ends at 240, each contract would be worth 10 × 100 = $1,000, and the total portfolio value would be $1,000,000 (before costs or settlement specifics). Since the problem statement does not provide tomorrow’s SPY price, the stated answer of 0 assumes SPY ends at or above 250.
- Summarizing the key idea: given the strike is well below the current price and the option is a near-term put, the value collapses to zero unless SPY’s price declines below 250 by expiration. With the information provided, the default, asked-for next-day value is 0, reflecting an out-of-the-money or near-expiry scenario.
- Final consideration: the lack of explicit tomorrow’s SPY price means we rely on the stated answer idea that the option expires worthless under the given conditions, aligning with a next-day portfolio value of 0. If the tomorrow price were below 250, the answer would differ substantially, and the analysis would need to recompute the intrinsic value accordingly.

Today, the SPY is at $285. A put on SPY that matures tomorrow with a strike of $250 has a price around $0.01. I spend my whole capital of $1,000 on buying that put. The portfolio's for the next day is $ (a number). 多项填空题
