Apache appears to have some of the best leases. While Pioneer is zooming up, look at the leases near the Pioneer leases. This map shows that Apache is in a strong position. I will hold onto my Apache stock and wait for it to zoom. Here is the lease map. Apache is drilling more wells than Pioneer.
Lack of getting the Spraberry/Wolfcamp story out, Egyptian unrest, and having operations that take on exploration risk from wildcatting (now really an unnecessary expense in this oil and gas environment where shale development eliminates the need to take on any exploration risk) I think have hurt APA.
PXD is not in Australia, Canada, Argentina or Egypt, and PDX's domestic production growth outpaced APA's last year. PXD's float is half of APA's, and institutional ownership is 15% greater than APA's. PXD had 10B less debt than APA, prior to APA's recently-announced divestitures, and almost four times as much cash. Don't give up on APA, which has recognized the error of its ways and refocused on domestic production. Provided prices don't tank, you could have a front row seat to PXD or EOG-like share price action in the not-too-distant future. Certainly, APA is better to chase after the fantastic 2013 runs of PXD and EOG.
