The Globe and Mail reports in its Monday edition that strategists and investors have largely held faith in the market despite stocks' recent wobbles. A Reuters dispatch to The Globe says that some, though, are growing more cautious. Reasons for optimism include the relative outperformance of the U.S. economy compared with Europe and China, and signs the so-called profit recession among S&P 500 companies may be over. Still, worries over an economic slowdown in China and concerns that U.S. corporate margins will shrink have led some market participants to believe squeezing more gains out of stocks will grow more difficult. The S&P 500 information technology sector lost more than 2 per cent this past week after news that Beijing had ordered central government employees to stop using iPhones for work. Apple shares fell 6 per cent for the week on fears the company and its suppliers could take a hit from rising competition from China's Huawei. "We think we are still in a bull market that will hit new highs before the end of the year, but it will be a choppy road," said Ed Clissold, U.S. strategist at Ned Davis Research. The U.S. central bank is widely expected to hold benchmark rates steady at its Sept. 20 meeting.
