Shares of AerCap Holdings NV (AER.N) fell sharply after the aircraft lessor said it was not in discussions with any party regarding a sale.
The company's shares have run up 16 percent since last Tuesday, when aviation news portal Flightglobal.com reported that AerCap had hired Goldman Sachs to look at opportunities.
AerCap, in a regulatory filing on Monday, said it was exploring options, including a possible sale, but had not engaged any financial adviser.
The company's shares were trading down 6.5 percent at $11.92 in morning trade on the New York Stock Exchange.
