using options to recover from a big move against me when buy a stock for shareholder benefits - RCL attempt to repair position

Shareholder Benefits Owning shares of a company can entitle you to special benefits when consuming products or services.  For example, Royal Caribbean Cruises (RCL) provides $100 onboard credit per Stateroom on Sailings of 6-13 nights.  With an upcoming cruise booked and most of my portfolio in cash, I decided to take advantage of this offer.  I've done a few cruises in the past and definitely enjoyed Royal Caribbean, especially having young children; and can imagine I will take more cruises with them in the future. The Purchase of Shares I didn't do any deep Fundamental or Technical Analysis, but looked at a 5 year chart seeing the stock priced at $135 before the COVID-19 pandemic, and during the pandemic reached a low of around $24.  When I purchased the shares it was $40 and dropped in price for the 2 preceding days.  Since I bought at the end of the day, I figured I would sell a call option (overwrite) the next day as the volatility was high around 85%....

How does theta change through time when selling strangles? SPY, META, IEF

What is Theta? Theta is amount of value that an option position changes each day due to the passage of time.   For example, SPY closing at 411.99 and Implied Volatility (IVOL) 22.58% SPY 9/16/22 (47 DTE) Strike delta price theta 376P -0.15 3.12 -0.09 440C 0.15 1.97 -0.07 The above table shows that the 376 Put has a theta of -0.09.  This means the option will lose $9 a day (each contract represents 100 shares so -0.09 x 100 = -$9. To standardize, the theta/price is a ratio that can be used.  In our example  -$9/411.99 => -0.02%. Table of Theta for 15 delta Strangles for SPY, META, and IEF Information was pulled from market data on 7/31/2022 taking the initial strikes and seeing how the data changes for different upcoming Days to Expiration (DTE).  (15 delta Strangles for SPY correspond to 376P and 440C).

Trading Ethereum (ETH) merge? Are the CME Ethereum Options on Micro Futures markets reasonable?

Ethereum Merge Brief Background Most people are aware of Proof-of-Work (consensus mechanism to validate blocks on the blockchain - this is done with miners solving math problems (work)).  Ethereum, the second largest Crypto Currency is moving from a Proof-of-Work to Proof-of-Stake (consensus mechanism that validates blocks through a validator (like voting) system).   The main reason for doing this is to get away from miners wasting electricity solving useless math problems to a system that doesn't waste energy on miners.   One argument against moving to Proof-of-Stake, is that it becomes more about controlling a large number of validator nodes (so in a sense, the larger validators have more say, whereas Proof-Of-Work rewards are more 'fair' as it is randomly distributed. Either way you look at it being positive or negative, it is an event that can be traded as the current estimated merge date (the date the blockchain switches from Proof-of-Work to Proof-of-Stake...
