The improbable story making the rounds today of the 17-year old whiz kid of Wall Street who is rumored to have made $72 million trading the markets, while still in high school, is being widely disputed.

Mohammed Islam, the alleged teenaged prodigy, said he had no idea where that dollar figure came from and that it's not accurate.

Instead the figure is believed to be a few million dollars, but Mr. Islam declined to be more specific.

"The attention is not what we expected – we never wanted the hype. This was about friends trying to make something exciting together, " Mr. Islam said in an exclusive CNBC interview.
