Small-cap stocks moved tightly with the major indices Wednesday, delivering a slight afternoon recovery after a bumpy morning in the red.

Among the biggest gainers was Hawaii's

An S&P SmallCap component,

Shares of the company, which makes electronic scoreboards and other digital display equipment, retreated 2% to $24.62.

Also sinking on disappointing guidance was
