Check out this headline from ShippingWatch, "Morgan Stanley: Iran deal could send tanker rates soaring."
The gist of the article, and, according to ShippingWatch, Morgan's comments, are that a repeal of oil sanctions on Iran would flood the international market with more crude and that tanker rates, in particular VLCC, would soar.
TNP is breaking out above $8 as I type this. NNA is looking good for a move over $4 in the near future. I remain very bullish on tanker rates and the stocks, whose performance has significantly lagged their underlying fundamentals.
