Option Price changes as you get closer to earnings (but stock remains unchanged)
How does option price change with stock price?
The current stock price is fairly straightforward. The movement of the price of the stock up or down has a direct, though not equal, effect on the price of the option. As the price of a stock rises, the more likely it is that the price of a call option will rise and the price of a put option will fall.
Why did my option price change?
As interest rates rise, call option premiums increase. Higher rates increase the underlying stock’s forward price (the stock price plus the risk-free interest rate). If the stock’s forward price increases, the stock gets closer to your strike price, which we know from above helps increase the value of your call option.
Why do option prices change after market close?
Why Are Stock Prices More Volatile in After-Hours Trading? The number of participants in after-hours trading is a fraction of those during regular market hours. Fewer participants means lower trading volumes and liquidity, and hence, wider bid-ask spreads and more volatility.
Do options lose value as they get closer to expiration?
As the time to expiration approaches, the chances of a large enough swing in the underlying’s price to bring the contract in-the-money diminishes, along with the premium. This is known as time-decay, whereby all else equal, an option’s price will decline over time.

Does theta decay throughout the day?
If you’re talking about just Theta, the amount of decay due to the passage of time (all else being equal), then theoretically, the time value is a continuous function, so it would decay throughout the day (although by the day of expiry the time value is very, very small).
