The Financial Post reports in its Tuesday, Nov. 18, edition that as traders rolled into the office Friday, they were greeted with a choice, lock in profits as futures on the S&P 500 index were pointing to another brutal day of selling, or heed the advice of Wall Street strategists and buy the dip. A Bloomberg dispatch to the Post reports that they chose the latter, making calls from trading desks at Barclays and UBS Group and the researchers at Wells Fargo Securities look prescient. U.S. stocks reversed a drop of more than 1.4 per cent to end the day little changed. The Friday rebound calmed nerves across Wall Street that had become frayed by signs the artificial intelligence trade was faltering and the U.S. Federal Reserve was no longer a lock to cut interest rates. It was not just a one-day call. The Wall Street prognosticators say any pullbacks between now and the end of the year provide opportunities to add to positions. Their optimism is based on seasonal patterns that show year-end rallies are far more common than not. Underpinning the call is faith in Corporate America after a strong earnings season that brought profit growth of nearly 15 per cent. The U.S. economy, while cooling, remains relatively strong.
