The SLT spreadsheet explaining the short sale of SLT was blogged in correctly
I forgot to add one important factor in: We need to buy back the SLT FEB. 22.5 PUT to CLOSE ( for around $3.00 - $3.20 DEBIT )
That would make our potentially profit less attractive, but still viable.
The corrected scenario should look like this which includes buying back the SLT February 22.5 put to close ( see highlighted in YELLOW )
Sorry for the confusion. It should make sense now. It was probably due to the fact I did the SVNT scenario first which does not require the buying back of the short put
