At the risk of sounding overly simplistic, since management has announced its intention to purchase up to 100 million shares, what motivation would management have to support the pps prior to the completion of its purchase of the desired number of shares? If management is serious about this buy back (which I understand to be discretionary, and not a binding commitment to purchase any specific number of shares), wouldn't management want the lowest pps possible?
If this reasoning is correct, I would not anticipate any action or PR by PBLS that would enhance the pps until the buy back is done.
IMHO, of course.
Disclosure: I am long.
