Okay, so some people who have a lot of money are trying to guess if a company called MongoDB will do well or not. They use something called options, which are like bets on the future of the company's stock price. Some of these people think the price will go up, and some think it will go down. Right now, they expect the price to be between $260 and $450 in the next few months. There are also some experts who study the company and give their opinions on how much the stock should cost, but sometimes they disagree with each other. Some of them think it's a good time to buy the stock, while others are more careful. Read from source...

Possible answers:

- The best option is to buy a call spread, which involves buying a call option at a lower strike price and selling another call option at a higher strike price. This strategy limits the maximum loss to the difference between the two premiums paid, but also caps the maximum gain at the difference between the two strike prices minus the net premium received. The advantage of this strategy is that it allows the investor to benefit from a rise in the stock price while reducing the cost basis and the risk of a sharp drop. For example, if the stock price reaches $450 by expiration date, the maximum gain would be $50 ($450 - $400 - $10), which corresponds to a 26% return on investment.
- The second best option is to buy a call vertical spread, which involves buying a call option at a specific strike price and selling another call option at a higher strike price with the same expiration date. This strategy also limits the maximum loss to the difference between the two premiums paid, but offers more flexibility in adjusting the potential gain depending on the stock price movement. The investor can profit from a rise in the stock price above the short call option strike price, while limiting the exposure to a significant drop below the long call option strike price. For example, if the stock price reaches $420 by expiration date, the maximum gain would be $310 ($420 - $110), which corresponds to an 88% return on investment. However, this strategy also entails more risk than a call spread, as it requires a greater initial investment and exposes the investor to unlimited losses if the stock price exceeds the higher call option strike price.
- The third best option is to buy a put vertical spread, which involves buying a put option at a specific strike price and selling another put option at a lower strike price with the same expiration date. This strategy also limits the maximum loss to the difference between the two premiums paid, but offers more flexibility in adjusting the potential gain depending on the stock price movement. The investor can profit from a decline in the stock price below the short put option strike price, while limiting the exposure to a significant rally above the long put option strike price. For example, if the stock price reaches $300 by expiration date, the maximum gain would be $425 ($300 - $95), which corresponds to an 142% return on investment. However, this strategy also entails more risk than a call spread, as it requires a greater initial investment and exposes the investor to unlimited losses if the stock price drops below the lower put option strike price.
