US SMALL/MIDCAPS-Stocks up after strong jobs data

NEW YORK, May 6 (Reuters) - Shares of small-cap and mid-cap companies rose on Friday after a surprisingly large jump in U.S. payrolls boosted investor confidence in the economic recovery.

The S&P MidCap 400 index .MID rose 0.6 percent while the S&P SmallCap 600 index .SML advanced 0.9 percent. In comparison, the benchmark S&P 500 .SPX gained 0.7 percent.

The rally was broad with industrials, materials and energy stocks among the top gainers after a sell-off in the previous session on concerns that global industrial demand is on a downward spiral.

U.S. employment increased more than expected in April as private companies created jobs at the fastest pace in five years, pointing to underlying strength in the economy, even though the jobless rate rose to 9.0 percent. For details, see [ID:nOAT004799]

“Our concern is that between now and the July reporting season, the market will be susceptible to heightened volatility and downward pressure on prices. However, we believe any weakness will prove transitory, in other words, a spring break,” said Jonathan Golub, strategist at UBS in New York.
