Shares of

CommScope

(CTV) - Get Report

were among the

NYSE's

winners Tuesday, rising 11.9% after the company posted first-quarter results that topped Wall Street estimates and forecast better-than-expected second-quarter sales.

Excluding items, the cable maker posted earnings of $6.9 million, or 11 cents a share, on sales of $309.1 million. Analysts polled by Thomson First Call were expecting earnings of 5 cents a share on sales of $295.7 million. A year ago the company earned $3.6 million, or 6 cents a share, on sales of $235.1 million. Sales gains in the most recent quarter were helped by price increases that were implemented as a response to higher raw-material costs. Looking ahead, CommScope forecast second-quarter sales of $320 million to $340 million. Analysts had been expecting sales of $316.6 million. Shares traded up $1.70 to $15.96.

Safeway

(SWY)

fell 4.5% after the grocery-store chain posted first-quarter results that topped expectations but warned that second-quarter earnings would fall short of estimates. The company earned $131.3 million, or 29 cents a share, on sales of $8.62 billion. Analysts were expecting earnings of 25 cents a share on sales of $7.96 billion. Looking ahead, Safeway predicted that second-quarter earnings would be similar to first-quarter results. Safeway said that about half of its first-quarter upside surprise "was due to Easter sales and operating profits that were recorded in the first quarter, but were reflected in second-quarter analyst consensus estimates." The timing of investments in marketing and branding will also have an impact on second-quarter earnings. Analysts are looking for second-quarter earnings of 34 cents a share. Shares traded down 99 cents to $20.98.

Shares of

Masco

(MAS) - Get Report

fell 6.6% after the building-products maker posted first-quarter earnings that fell from a year ago and forecast second-quarter earnings that are below expectations. The company posted earnings from continuing operations of $212 million, or 48 cents a share, on sales of $2.97 billion. Results included a gain of 6 cents a share from the sale of financial investments. First-quarter results also benefited from a reduction in the company's tax rate, which added 2 cents a share -- and helped offset a 2-cent loss from unfavorable currency translation. Analysts were expecting earnings of 46 cents a share on sales of $3 billion. Looking ahead, Masco forecast second-quarter earnings of 58 cents to 62 cents a share, well below the 66 cents a share that analysts had been expecting. Shares traded down $2.11 to $29.89.

Papa John's International

(PZZA) - Get Report

rose 6.4% after the pizza chain posted first-quarter earnings and sales that beat expectations and raised its full-year earnings outlook. The company earned $10 million, or 59 cents a share, on sales of $252.4 million. Excluding items, the company would have earned 68 cents a share. Analysts were expecting earnings of 59 cents a share on sales of $228.4 million. Looking ahead, Papa John's now expects 2005 earnings of $2.35 to $2.41 a share, up from previous guidance of $2.27 to $2.35 a share. Including the consolidation of BIBP Commodities, a cheese purchasing entity, the company expects earnings of $2.58 to $2.64 a share. Analysts are expecting earnings of $2.30 a share. Shares traded up $2.22 to $36.97.

Looking ahead, Emerson now believes it will post 2005 earnings of $3.35 to $3.45 a share, representing growth of 12% to 16%, ahead of the 10% to 15% it had previously forecast. Sales, meanwhile, are expected to grow by 9% to 11%. Analysts are expecting earnings of $3.44 a share on sales of $17.1 billion, or sales growth of about 10%. Shares traded up $1.90 to $65.90.
