Predict Earnings Plays Like a Pro with the Moomoo Option Price Calculator!

1. Introduction
Imagine this:
It's a week before one of your favorite tech company's quarterly earnings release. You're feeling a rush of adrenaline, mixed with the sharp tang of anticipation. The company has a track record of beating estimates and you're bullish about this time as well. You are convinced the stock price will skyrocket, and in this frame of mind, you decide to buy a call option, betting that the stock will rise after the earnings announcement.
You select a call option with a strike price slightly above the current market price, set to expire in a few weeks. The Implied Volatility (IV) is elevated, as it typically is before earnings, but you don't pay it much mind. You're focused on the upside potential. You're poised to make a huge profit when the stock shoots up following the earnings announcement.
The day arrives. The company releases their quarterly report and, just as you predicted, they beat earnings estimates. You could almost hear the pop of champagne bottles from the other investors who shared your belief. But when you rush to check the price of your call option, expecting to see a hefty profit, your heart sinks. Despite the positive earnings report, the price of your option has plummeted. You're in the red. But why?

Currently, Coinbase is trading at $76.79. Given your bullish outlook, you decide to purchase an At-The-Money (ATM) call option with a strike price of $76, set to expire on August 11th. You examine the option chain and find a wide bid-ask spread: the bid is $9.85 and the ask is $10.20. This means market participants are willing to sell the option for $9.85 (ask) and buy it for $10.20 (bid).

A spread this wide can make it challenging to determine the optimal price to enter the trade. This is where the Moomoo option price calculator, utilizing the Black-Scholes model, comes into play.
By inputting the relevant parameters (current stock price, strike price, time until expiration, risk-free interest rate, and the stock's volatility), the option price calculator can estimate the fair value of the option.

With this estimated value, you can then compare it to the current bid and ask prices. If the estimated fair value is closer to the bid, you might consider placing a limit order at a price below the current ask, towards the estimated value. If it's closer to the ask, it might be worth buying at the market price, particularly if you're confident in your bullish outlook. However, you might also decide to wait and see if the ask price comes down closer to the fair value.

2.1 Understanding Theta Decay
Now that we've explored how an option price calculator can help you navigate the market bid-ask spread, it's time to consider another critical aspect of options trading: time decay, also known as Theta decay.

As each day passes, the time value portion of an option's price diminishes – this is Theta at work. For example, with our Coinbase call option, the option price calculator estimates the theoretical price at $9.49 on July 7. However, if we move the calculator's date forward to August 7, the day before the earnings announcement, and keep all other factors equal, the theoretical price drops dramatically to $3.77.

This reduction in value, which occurs even if the underlying stock price and all other option Greeks remain constant, is due to Theta decay.
This example highlights the importance of considering Theta when trading options. If you're long an option, Theta is your silent adversary, gradually eroding your option's value as time passes. So, how can you mitigate this?
One alternative is to purchase options with a longer time until expiration. Options with more distant expiration dates are less affected by Theta, especially far from expiration. Thus, by buying further out, you can reduce the impact of time decay on your option's value.
Another strategy you might consider is selling options instead of buying them. In this scenario, Theta becomes your ally instead of your foe. As an option seller, you benefit from the time decay, as it reduces the value of the option you've sold, potentially allowing you to buy it back later for less or let it expire worthless.
Finally, a more complex strategy involves spreads where you both buy and sell options, aiming to offset the negative effects of Theta decay. However, these strategies require more experience and understanding of options trading.
No matter the strategy you choose, it's clear that the Moomoo option price calculator is a valuable tool in visualizing and understanding the impact of Theta decay. By using this tool in conjunction with a thoughtful trading strategy, you can navigate the complexities of options trading and make more informed decisions.

2.2 Predicting the IV Crush
If Theta is the silent adversary of options trading, Implied Volatility (IV) is the invisible threat, especially when trading around earnings announcements. By using tools like the Moomoo option price calculator and market data from free resources such as Market Chameleon, you can better predict and prepare for this so-called "IV Crush".

Consider this: during Coinbase's last earnings announcement, the implied volatility (IV30) going into earnings was 112.0. Following the earnings release, the IV dropped to 89.2, resulting in an IV Crush of approximately 20%. Five days after earnings, the 30-day IV was 90.2. By comparing how Coinbase's implied volatility changed around earnings for the last 12 quarters, we see an average implied volatility crush of 16%.
Let's explore how this volatility crush could impact our Coinbase call option with a strike price of $76, set to expire on August 11th. Suppose we purchase this option on the day before earnings, when the IV is at 112, similar to the previous earnings. Using these parameters in our option price calculator, we find an expected option price of $4.43.

But, what happens after earnings? Let's model a 20% IV crush, similar to the last earnings release, which drops the IV to 89.2. The expected price of our option, assuming the stock price hasn't moved, would drop to $2.90. That's almost a 34.5% loss largely due to the decrease in implied volatility!

In fact, in order to just about break even after such an IV Crush, the stock price would need to increase to $79.2, which would result in an expected option price of $4.44.

Now, you might wonder if this price move is even feasible, especially considering the average actual earnings move for Coinbase is 8.3%. If your analysis and conviction lead you to believe that such a price move is likely, then this could be a potentially profitable play despite the IV crush. However, it's important to remember the substantial risk involved.

This example highlights the critical role an option price calculator can play in predicting and preparing for IV crush. By modelling different scenarios, you can better understand the potential risks and rewards of your options trades, enabling you to make more informed decisions.

2.3 A Contrarian Play: Profiting from IV
So far, we've talked about how Theta decay and IV Crush can negatively impact your long options positions. However, as an options trader, you can actually turn these dynamics to your advantage, particularly if you're willing to explore more advanced strategies. Let's consider an example where you can profit from selling out-of-the-money (OTM) put options, despite a drop in the underlying stock price following earnings.
Imagine it's August 7th, the day before Coinbase's earnings announcement. The stock price stands firm at $76.5 and IV is at a heightened level of 112, reflecting market participants' anticipation of the upcoming earnings.
In this situation, you could decide to sell an OTM put option, specifically the $60 put. According to the option price calculator, with the IV at 112, the theoretical price of this put option is $0.10. By selling this option, you would receive a premium of $10 per contract.

Now let's fast forward to August 9th, the day after earnings. Even in a bearish scenario where Coinbase's stock price drops to $70.4 (predicted by the average 8.3% move from Market Chameleon), your position could still be profitable. If the IV crushes down to 89.2 as anticipated, the theoretical price of your $60 put would fall to $0.05.

At this point, you could buy back the put option you sold for just $5 per contract, netting a profit of $5 per contract – a 50% return on the initial premium received. Despite the stock price dropping post-earnings, you would have profited from the decline in implied volatility, demonstrating the power of selling options in high volatility scenarios.
This strategy isn't without its risks – should the stock price fall significantly below your strike price, your losses could be substantial. However, with a careful assessment of the risk-reward profile and a sound understanding of the potential outcomes, selling OTM put options around earnings can be a viable strategy to profit from the often predictable IV Crush.
