The Financial Post reports in its Friday, June 27, edition that with technology stocks driving major U.S. indexes to near record highs, analysts warn of a potential sell-off if other sectors do not join the rally. A Bloomberg dispatch to the Post reports that the S&P 500 has rebounded sharply, sitting just under an all-time high, but market breadth remains stagnant, with the percentage of S&P 500 members above their 200-day moving average unchanged since May. Meanwhile, the equal-weighted S&P 500 is over 4 per cent below its November record. Chart watchers suggest that U.S. stocks may lose momentum in the coming months unless there is significant support from financials, transports and small-cap companies. For now, the S&P 500 could continue to rise due to momentum, as long as there are no major shocks in trade or geopolitics. Janney Montgomery Scott director Dan Wantrobski says: "The markets are very overbought on a short-term basis and leadership is concentrated heavily toward S&P 500 and Nasdaq 100. If breadth does not follow the breakouts in S&P and Nasdaq, then we will be on the watch for a correction." Mr. Wantrobski points to August as a potential area of weakness.
