"So much for the summer doldrums," said Richard Peterson, an analyst with Thomson First Call. "This is shaping up to be one of the busiest weeks for IPOs this year."

K&F Industries (KFI - Cramer's Take - Stockpickr), a long-established manufacturer of aircraft parts, made its debut in the stock market on Monday. Its IPO priced 18 million shares at $17.50, toward the high end of estimates, and the shares gained 5.4% in their first day to close at $18.45.

"The recent success in the IPO market reflects the fact that investors are getting more risk-averse," said Michael Sheldon, chief market strategist with Spencer Clarke LLC. "Despite the fact that the Fed has raised interest rates so many times in the past year, a lot of liquidity remains in global financial markets. That liquidity provides fuel for equity IPOs and other asset classes."
