NEW YORK, July 17 (Reuters) - Trian Fund Management's Nelson Peltz has amassed a "big stake" in chemicals maker DuPont , CNBC said on Wednesday.

Shares of DuPont rose 4.8 percent on the news of Trian's stake. At the CNBC Institutional Investor Delivering Alpha Conference, Peltz declined to comment in response to questions by CNBC host Andrew Ross Sorkin on his DuPont interest.
