For the year to date, major rallies have come as a result of these upside surprises. But investment opportunities can still be found as valuations remain stable and a bullish outlook supports key areas of the defense sector. Here, we look at three companies well-positioned for continued growth. Precision Castparts ( PCP) Precision Castparts showed a 23% increase in its fiscal fourth-quarter earnings on improved sales in all segments of its cast metal parts business. The company makes castings and metal forgings for gas turbines and airplanes, and its revenue performance has seen gains for each of the last three years. The market environment has been widely supportive of these trends, with steady improvements seen in aerospace demand. Strong revenue performance has also enabled the company to broaden its operations through acquisitions. In January, Precision Castparts purchased Titanium Metals Corp. for $2.9 billion, in a move that will allow for expansion in Precision's titanium capabilities. In March, the company outlined an agreement to buy SKF AB's metallic-rods unit for $52 million.
Precision's fiscal fourth-quarter profits came in at $414.2 million, equal to $2.82 per share. This is a marked increase from the $336.1 million ($2.30 per share) seen the previous year. Sales rose by 25% to $2.44 billion. Analysts, on average, were looking for earnings of $2.75 per share on revenue of $2.51 billion for the period ending March 31. Areas of strength were seen in the company's forged products segment -- with gains of 31% to $1.12 billion -- and in air-frame products sales, which saw improvements of 40%. Trading with a P/E of 21.6, PCP stock has seen gains of nearly 14% for the year to date, making the company a strong option for momentum strategies. Triumph Group ( TGI) Triumph Group is another strong earnings performer, with fiscal fourth-quarter adjusted earnings from continuing operations coming in at $1.68 per share. This creates a 7% improvement from the $1.57 per share seen last year and compares well to the $1.59 per share expected by the consensus. In fiscal year 2013, adjusted income from continuing operations rose to $6.21 per share. This is an increase of roughly 24% from the $5.01 seen in fiscal year 2012.
