Herbjørn Hansson of North American Tankers (NAT) pulls this exact same maneuver on a regular basis, and it's pretty annoying unless you're expecting it. NAT is a high-yield company whose stock price increases, then gets decimated when Hansson suddenly spends the cash. Then the cycle repeats.
Cramer loves Hansson for some reason. I used to own NAT but got sick of dealing with surprises... same may be true for ETP.
