UPDATE 1-JP Morgan upgrades DHT, General Maritime to overweight

(Adds details)

Oct 23 (Reuters) - JP Morgan Securities upgraded DHT Maritime (DHT.N) and General Maritime Corp GMR.N to "overweight" from "neutral," saying the companies have sufficient liquidity to meet capital commitments and are attractively valued.

"We believe DHT's relatively high cash flow visibility and dividend security reflecting the company's full-fleet contract coverage and its sufficient liquidity to meet capital commitments through at least year-end 2009," JP Morgan analyst Jonathan Chappell wrote in a note to clients.

Chappell said General Maritime's shares will outperform the peer group in the difficult spot rate environment on its relatively secure cash flows and limited financing risk.

JP Morgan Securities downgraded Frontline Ltd (FRO.N), Nordic American Tanker Shipping (NAT.N) and Overseas Shipholding Group (OSG.N) on a lower spot rate outlook for next year.

The brokerage removed Nordic from the U.S. analyst focus list and dropped its price target of $44 on the stock. Nordic shares closed at $27.33 on Wednesday. (Reporting by Anand Basu in Bangalore; Editing by Mike Miller)
