The raging tanker market is benefiting more than just tanker owner — at least in one case.

Shares of dry-trade owner Scorpio Bulkers (ticker symbol: SALT) soared to an 18% gain Wednesday on the New York Stock Exchange as investors caught on to the ability to play tankers through SALT's holding in sister listing Scorpio Tankers (ticker symbol: STNG).

Investors were aided greatly by a note from J Mintzmyer, analyst/investor with Value Investors Edge, who reminded the market of the arbitrage in a note published on the Seeking Alpha website on Wednesday morning.
