Shares of OMNOVA Solutions fell more than 10 per cent Tuesday, a day after the specialty chemicals maker reported quarterly results below Wall Street estimates.

Trex Shares Decline, SunTrust Downgrade Cites Slowing Industry

A SunTrust Robinson Humphrey analyst on Tuesday downgraded Trex Co., maker of composite deck materials, pointing to slower times for the home and deck-building industries.

Shares declined $3.40, or 12 percent, to $24.56 with above-average volume in midday trading on the New York Stock Exchange.

Analyst Keith Hughes in a client note downgraded Trex, which sells wood and plastic composite decking materials through wholesalers, to "Neutral" from "Buy."

He cited a slowing composite decking industry, beginning in August and continuing into September.

Declining sales volumes after a strong second quarter have led manufacturers to slash prices, the analyst wrote.

"While some "end of year discounting" is normally seen during this period, the current trend is much more serious than in years past," wrote Hughes.

Dropping lumber prices, coupled with weakness in the home builder sector, could be pushing down composite lumber prices, the analyst wrote. An overall deterioration in consumer spending is one reason demand is down, he added.
