Roll Out-and-Up -- Alexion Pharmaceuticals Inc. Covered Calls

Today is the options expiration date for the initial Covered Calls position in Alexion Pharmaceuticals Inc. (ticker ALXN).  The stock price was well in-the-money and with the time value having declined to $.05, the Covered Calls Advisor decided to roll out the two Alexion November 1st, 2019 $100.00 Call options to November 15th  and up to the $105.00 strike price today when the stock price was trading at $107.80.  The original Covered Calls position was established when the price of ALXN was $100.94 and the subsequent quarterly earnings report exceeded analysts' expectations, so the stock price has risen substantially since then.

A Call options roll out-and-up limit order was placed today at a net debit of $3.15 per share.  The simultaneous rollout transaction was soon executed as follows:
Bought-to-Close 2 Alexion Nov 1st, 2019 Call options @ $7.85
Sold-to-Open 2 Alexion Nov 15th, 2019 Call options    @$4.70
Net Debit Cost per Share                                                  $3.15

As detailed below, a potential investment result is +5.4% absolute return in 25 days (which is equivalent to a +78.8% annualized return-on-investment) if Alexion stock closes above the $105.00 strike price on the November 15th options expiration date.
