NEW YORK ( TheStreet) -- Several small-cap stocks were moving on above-average volume during Thursday's session.

Harmonic ( HLIT) dropped by 64 cents, or 10.8%, to $5.30 after the company reported a third-quarter adjusted profit of 5 cents a share, falling short of the Thomson Reuters average estimate of 6 cents a share. Volume topped 1.4 million shares, compared to the 50-day average daily volume of 722,000, according to the Nasdaq.

Cytokinetics ( CYTK) tumbled by 75 cents, or 17.6%, to $3.52 Needham downgraded the stock to hold from buy due to the delay of its CK-452 heart drug treatment program and lack of near-term catalysts to drive valuation.

Volume topped 1.2 million shares, compared to the 50-day average daily volume of 602,000, according to the Nasdaq.
