Macquarie Group soared $6.30 or 24.18 per cent to $32.35 within 15 minutes of the market opening, after plunging 23 per cent yesterday.
The group, which manages assets such as airports and toll roads globally, has suffered from investor concerns over companies carrying large debts in the wake of the collapse of US investment giant Lehman Brothers.
The bank is one of the best-known of Australian financial institutions, with its name regularly short-listed in the past among bidders for assets such as the London Stock Exchange, Prague airport or Berlin television tower.
The rise in Macquarie shares reflected a bounce in the wider market, which opened up 1.6 per cent higher after a rally on Wall Street overnight.
