Final answer:
The maximum profit for purchasing a put contract can be substantial, depending on the decrease in the underlying asset's price, but we need more information to calculate an exact profit. The maximum profit is the strike price minus the premium paid, times the number of shares, if the stock price drops to zero.
Step-by-step explanation:
When you purchase a put contract, you are buying the right to sell a specified amount of an underlying asset at a set price within a defined time frame. The maximum profit that you could gain from a put option is technically unlimited, as it benefits from the underlying asset's price decrease. However, since this question specifies a put premium of $10 and does not provide information on the actual stock price or the exercise of the put option, we cannot determine an exact figure for maximum profit without additional data.
If you had specified data regarding the stock's price plummeting to zero, theoretically, the maximum profit would be the strike price minus the put premium of the contract (195 - 10 = $185 per share, multiplied by 100 shares per contract), if the underlying stock became worthless. But without such information, we cannot give a precise amount for the maximum profit attainable with the MBI March 195 put contract.
