I am still talking pre split era. If you look at a 5 year chart for RPC in the period from March 1 to April 15 on average the stock moves about 30 % in that time frame. If you take 14 as the low and add 30 % it should take you to about 18.20 before you hit resistance, and that is based on the 5 year history without any premium attached to Middle East conflict etc.
On Wednesday the day the stock was at the low about 20 % of the April 15 calls changed hands. I bought at 90 cents that day and sold a few on Friday. But the amount of buyers to sellers for those calls on Friday was intense with hundreds at the bid and only a few on the sell.
Precious few calls were sold despite the call option increasing in 40 % since Wednesday. In my view the stock will hit 20 dollars before April expiry.
