Shares of Rockwell Collins ( COL) were among the NYSE's winners Wednesday, rising 6% after the company raised its 2005 outlook.

The maker of aviation electronics equipment now expects earnings of $2 to $2.10 a share, up from previous guidance of $1.85 to $1.95 a share. Analysts polled by Thomson First Call had been expecting earnings of $1.93 a share. Sales, meanwhile, are now expected to exceed Rockwell's previous guidance of $3.2 billion by $75 million to $100 million. Analysts had been expecting sales of $3.21 billion. Strong sales growth in the company's first quarter and enhanced operating efficiencies -- especially in its commercial systems business -- led to the revised outlook. Shares traded up $2.26 to $39.75.

RC2 ( RCRC) fell modestly after the maker of toys and hobby products warned of weak fourth-quarter sales. Excluding the acquisitions of Playing Mantis and The First Years, the company's sales grew just 3% on a year-over-year basis. Total sales, including the acquisitions, rose 39%, but RC2 said the results were "lower than expected." As a result, 2004 earnings are now expected to be below the company's previous guidance of $2.15 to $2.20 a share. Analysts had been expecting earnings of $2.16 a share. RC2 said margins were hampered by increased costs, including costs associated with 2004 acquisitions, product mix, and discontinued products. Shares traded down 7 cents to $29.35.

Shares of UPS ( UPS) fell 7.4% after the package delivery company cut its fourth-quarter earnings outlook. Excluding items, UPS now expects earnings of 75 cents to 76 cents a share, down from previous guidance of 83 cents to 87 cents a share. Analysts had been expecting earnings of 85 cents a share. The company blamed the shortfall on a slowing in domestic package volume and higher operating costs that were caused by severe weather in the midwestern U.S. during its peak operating season. Looking ahead, UPS said that 2005 earnings would grow by 13% to 17% over 2004's results. Analysts are expecting 2005 earnings of $3.43 a share. Shares traded down $6.12 to $77.18.

Silgan Holdings ( SLGN) rose 2.1% after the packaging products company raised its fourth-quarter earnings outlook. The company now expects to post earnings of at least 76 cents a share, up from previous guidance of 42 cents to 62 cents a share. Strong sales volume late in the quarter and a $3 million pretax benefit related to a litigation settlement led to the earnings revision. Silgan plans to release fourth-quarter earnings on Feb. 9. Shares traded up $1.20 to $58.77.

Shares of Big 5 Sporting Goods ( BGFV) rose 1% after the company posted fourth-quarter sales above expectations. For the 14 weeks ended Jan. 2, the sporting goods chain posted sales of $217.6 million, up from $191.8 million for the 13-week period a year ago. Analysts had been expecting sales of $212.5 million. Big 5 plans to deliver full fourth-quarter results on Feb. 9. Shares traded up 28 cents to $27.53.
