Here's how Matt Amodio, who racked up $1.5 million on 'Jeopardy!,' plans to invest his winnings - CNBC

Matt Amodio, whose prolific run on "Jeopardy!" came to an end earlier this week, told CNBC on Thursday he has no risky investment plans for his winnings.

I'm going to do long-term invest and hold," Amodio said on "Squawk on the Street.".

It's too much for me to keep track of," said Amodio, an Ohio native who's pursuing a doctorate in computer science at Yale University.

Although he often won in runaway fashion, Amodio told CNBC he's not totally shocked his "Jeopardy!" streak is over now.
