Very astute (or should I say asstoot?) observation,since chk rose 44.7% in the last 4 months,from$13.20 level. Are you implying that NOW IS THE TIME TO GET IN? You mean you already have missed the boat.
If you look at a chart of CHK,you will see that from the recent bottom,four times it has made lower bottoms and higher highs while rising 44.7%. Many times takeover prices are set at the closing average over the last 60 days.So every increase in chk price means we can expect a higher offer.
