TORONTO — The Toronto stock market was flat Tuesday afternoon amid concerns about whether a U.S. stock rally may be running out of steam and indications of slower than anticipated economic growth prospects.The S&P/TSX composite index ticked 2.52 points higher to 13,460.58 as the Canadian dollar fell 0.39 of a cent to 95.47 cents US.The Organization for Economic Co-operation and Development cut its 2014 forecast for global growth from 4% to 3.6%. The OECD cited U.S. fiscal uncertainty, the impact of the Federal Reserve tapering its asset purchases and weakness in emerging markets.U.S. markets were lower after indexes backed off Monday after hitting key technical levels, raising questions about whether American markets are due for their first serious retracement in two years.The Dow Jones industrials declined 19.66 points to 15,956.36, the Nasdaq fell 22.41 points to 3,926.65 and the S&P 500 index slipped 5.5 points to 1,786.03.Investors remained cautious a day after the Dow broke 16,000 and the S&P breached the 1,800 mark — both for the first time. The Dow alone has surged more than 20% this year and is up about 900 points since early October amid optimism that the Federal Reserve won’t be moving to cut back on its monthly US$85 billion of bond purchases until well into the new year.“You always have to be cautious when the market has gone up as fast as it has,” said Ian Nakamoto, director of research at 3MACS.“(But) any correction that could happen I would use it to buy the dips because valuations are still reasonable.”The TSX is up about 8.5% for the year so far, dragged down by the mining sector. Most other sectors have put in a solid performance, particularly financials, energy companies and industrials — companies Nakamoto thinks will likely take the TSX higher.“Much more of the direction of the TSX is going to be the financial and energy components because we have had such a correction in the mining sectors,” he observed.Commodity prices advanced and the energy sector was the strongest group, up 0.35% as December crude on the Nymex inched up 27 cents to US$93.30 a barrel.

The sector has been a major drag this year, plunging about 45% as global inflation remains very low while economic conditions are gradually improving, making bullion less attractive as a hedge.
