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%.

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%....
