Olympian Matt Grevers had the honor Thursday of ringing the opening bell at the NASDAQ.
The Lake Forest native rang the bell on Wall Street just days after coming home from London, where he won a gold medal in the men's 100-meter backstroke.
Grevers swam 52.16 seconds to set an Olympic record in the event, 0.38 seconds ahead of the previous mark set in 2008.
Grevers is no stranger to setting records. He took home a silver medal and set another record in the 2008 Beijing Olympics.
Traders hope the swimmer's golden touch will have a positive effect on the markets.
