To make a lot of money in not a lot of time, market players need to get into the next hot initial public offering, Jim Cramer told viewers of his "Mad Money" TV show Friday. AeroVironment, which is expected to go public next week and trade under the symbol AVAV, is the next hot IPO, according to Cramer. The company makes small unmanned aircraft used for surveillance, he said. Even though AeroVironment may have the risk of competition, it's the only company that makes a plane weighing less than a pound. That's what gives AeroVironment an edge, Cramer said. The Pentagon has been "pouring money" into it, as the small, quiet planes AeroVironment makes are used by the army "to spy what's happening 'over the hill,'" he said.
