Yup, with the potential for a short squeeze to intensify in the coming days, a multi-week run would certainly not surprise me...would make sence given that this period of seasonal strength for NG typically runs into late April.
Today was clearly another strong day and step in that direction, even as most 'bears' continue to shake their heads in disbelief at this upward move given the 'massive' supply and their prevailing view that this is an over-reaction to the Japanese nuclear situation. The main argument I see put forward is that this should not fundamentally impact U.S. domestic prices as only LNG from other countries is being shipped into Japan to fill near-term needs in the face of their energy crisis. When the panic subsides they expect NG prices to collapse back into their previous funk.
What most 'bears' fail to see though is that the change in the NG market is not about short term supply/demand disruptions resulting from Japan's crippled nuclear reactors, but rather a major sentiment shift across the overall global energy market, one that clearly favors NG, particularly in the U.S. where it is the key to energy security and independence. As 9/11 was for Gold, the tragic events impacting Japan will turn out to be THE game-changer for this commodity going forward. JMHO of course.
The next few weeks shall prove to be most 'interesting', no doubt...
