Shares of aircraft lessor AerCap Holdings NV (AER.N) rose 16 percent to a four-month high after a report that the company was exploring strategic options, including a sale.
Aviation news portal Flightglobal.com, quoting sources, said in its Twitter feed that AerCap had hired Goldman Sachs to look at opportunities.
Wells Fargo analyst Gary Liebowitz said AerCap, which had a market capitalization of $1.5 billion as of Monday, could fetch at least $17 per share.
That would represent a premium of more than 50 percent to Monday's closing price, Liebowitz said in a note to clients.
An AerCap spokesman declined to comment. The Flightglobal report could not be accessed by Reuters on its website.
AerCap shares were up 14 percent at $12.78 in early afternoon trading on the New York Stock Exchange. They touched a high of $12.97 earlier in the day.
