I think the comment on option expiration was right on target. Stock is holding near $45 all day.
Someone is in control-- look for a close just below $45 today so that all the $45 calls expire worthless.
I've seen it happen many time before.
Nice call on the option expiry indeed.
Too bad the price dropped, but a good chance this is for a few days allowing many (including me) to be buying more RNF and looking forward to distribution day coming.
