While imploding financial markets have zapped investors into spending paralysis, one Atlanta venture capital firm is going on a $400 million buying binge.

Arcapita Ventures plans to raise a petrodollar-fueled investment fund early next year, aimed at health-care, information technology and industrial technology firms on two continents.

“The best time to buy is when there’s blood on the streets,” said Stephen Fleming, Georgia Tech’s chief commercialization officer, echoing the “buy-low, sell-high” investment mantra. “For somebody that does have deep pockets and a long holding period, this is a good time to be investing.”
