At a media conference in Paris, Levy said that the global advertising market should stabilise in the first half of the year, with growth of 1% in the second half.
However, he once again warned the industry that the possibility of a war with Iraq was making it difficult to predict growth.
Levy has previously complained about the lack of visibility in the advertising marketplace. Nonetheless, he has promised investors that he will increase profit margins at the company he heads, following Publicis' takeover of Bcom3.
At the conference, he said that the 2002 operating margin for Publicis was expected to be in line with the 14.1% forecast last year. The figure for 2003 was likely to be 15%.
Publicis Groupe merged with Bcom3 in a $3bn (£2bn) deal in September. Levy has promised that the merger will deliver €60m (£38m) in savings, although the full effect will not be felt until 2004.
The holding company has already moved to close the D'Arcy network and move clients, including Procter & Gamble, to other groups, including Saatchi & Saatchi, Leo Burnett and Fallon Worldwide.
