good day to everyone. i have been placing my first trades on options over the last three weeks trying to speculate on the current earnings season. i have run into one recurrent situation that i wasn't expecting and i want to understand if there is any rule about the pricing of options that i had not properly understood previously. the situation i have in mind is the following:
___
1) if one buys any position in options, the price that one can sell those options back to the market for stays very close to what one paid for them for the duration of that day's regular session. it doesn't matter if the strike price is out, at or in the money; the profit - loss calculation always begins from 0 and the movement in the price of the underlying instrument is what will have the biggest influence on the price of the options.
2) however, if one buys any position in options and holds it overnight, the price of the options decreases dramatically from the same session one purchased the options in to the subsequent ones. i would have expected that the price of the options would stay roughly the same for the next sessions, plus or minus the movements in the price of the underlying and a small loss in value due to time decay (theta) but in several cases i have seen the price of the options i am holding drop almost to zero. the price of out of the money options will go almost to zero but even in the money options will open the following sessions with no other value other than intrinsic value.
i purchased calls for several companies before their earnings reports and even when the price of the underlying instruments moved in my favor and my positions went from being out of the money to in the money, i have made negligible profits when i was expecting my positions to be worth roughly the full price i paid for them plus the favorable price action. after fb, msft and akam reported earnings and the price of their shares was bid higher i was expecting to end up with 200 to 300% of the capital i had put at risk but the day after earnings my positions were worth only the updated intrinsic value and i barely made any profits. akam is the worst case as from the session following the earnings report my position has been displayed as a loser even when the underlying had moved 4% in my favor from the point i purchased the options (71.5 to 74.5).
___
¿is it the case that positions in options always lose all their value except for the intrinsic from the session one has purchased them to the posterior ones? ¿or this is just due to elevated implied volatility in anticipation of the earnings reports? i had been thinking one could use options to place swing trades using the signals from 15, 30 and 60 minute bar charts over several trading sessions (similar to what is displayed in the image below) but if options always lose so much value, even when one has been correct in anticipating the movements in price of the underlying instruments then that would just be impossible.

thanks in advance for your assistance, regards.
