New York markets are open for a half-session on Friday.Also in the background are concerns that the U.S. Federal Reserve may decide to start cutting back on its US$85 of monthly bond purchases if economic performance allows. Those purchases have kept long-term rates low and encouraged investors to pile into the equity markets, resulting in the S&P 500 charging ahead 27% year to date.However, an increasing number of investors believe that stocks have run their course for 2013 and are due for a pullback soon.“I would like to see this market take a breather,” said Jim Lauder, a fund manager for Wells Fargo Advantage Dow Jones Target Date Funds in New York.The energy sector was down almost 1%. The January crude contract on the New York Mercantile Exchange fell 75 cents to US$94.09 a barrel, even though the agreement does not loosen sanctions on Iran’s oil exports.The deal with Tehran announced on the weekend raises the possibility that a more comprehensive agreement would eventually allow Iran to restore oil production to pre-sanctions levels. That could add one million barrels of oil a day to world markets, which would be enough to meet the entire global growth in demand for 2014 projected by the International Energy Agency.Suncor Energy (TSX:SU) gave back 72 cents to C$37.24.The base metals sector shed about 1% with December copper up a penny at US$3.22 a pound.

Agnico Eagle Mines (TSX:AEM) gained 48 cents to $28.04 while Detour Gold Corp. (TSX:DGC) fell 50 cents or 11.7% to $3.77 amid an announcement that company founder and CEO Gerald Panneton has resigned, effective immediately.Industrials led advancers as Canadian Pacific Railway (TSX:CP) improved by $2.07 to $161.11.In corporate news, auto parts maker Martinrea International (TSX:MRE) was a major TSX decliner, down 77 cents or 8.37% to $8.43.
