Claymore Securities, a provider of exchange-traded funds, has introduced the Claymore/Delta Global Shipping Index exchange-traded fund on NYSE Arca.

According to the company, the exchange-traded fund (ETF) will seek to replicate the Delta Global Shipping Index, which was developed and is maintained by Delta Global Indices, a wholly owned subsidiary of Delta Global Advisors.

The Delta Global Shipping Index includes companies that derive at least 80% of their revenues from the seaborne transport of goods or the operating and/or leasing of ships. Additionally, constituents must have market capitalizations of at least $250 million and a 30-day average daily trading volume of at least $2 million.

Claymore/Delta Global Shipping Index ETF (SEA) and other Claymore ETFs can be purchased through most brokerage accounts.

Christian Magoon, president of Claymore Securities, said: Maritime shipping is the primary means of international transportation for raw materials and finished goods, and we are pleased to be the first ETF provider to offer investors access to a global portfolio of 30 maritime shipping stocks with a current combined market cap near $50 billion.
