Small-cap stocks were buoyed by the cheery broader market Tuesday, and among the biggest movers was Bob Evans Farms ( BOBE).

Shares rose 15.2% to $29.60 on the heels of the chain restaurant operator's fiscal second-quarter earnings.

New Jersey's Hill International ( HINT) saw shares climb 10.5% to $11.05 after the construction services and management firm posted third-quarter income of 15 cents a share, or $3.8 million, beating analysts' expectations of 11 cents a share. Last year, the company made 12 cents a share, or $2.9 million.

On the losing side, shares of Superconductor Tech ( SCON) were falling 7.8% after the California-based communication-equipment maker reported a third-quarter loss of $2 million, or 16 cents a share.
