Aggressive Growth – Siliconware Precision Industries Co., Ltd. (Nasdaq:SPIL)

Siliconware Precision Industries Co., Ltd. is a cheap stock relative to its growth prospects. At about 11.5x next year's estimates, the stock trades well below its projected long-term growth rate of 20%. Over the past month, this year's earnings estimates have increased four cents to 82 cents per share. The company has comfortably exceeded analyst expectations in eight consecutive quarters. Both analysts covering the stock raised their numbers for next year.

Growth & Income – Harsco Corporation (NYSE:HSC)

Harsco Corporation has topped the consensus earnings estimate for 15 consecutive quarters by an average margin of 16.2%. The company recently reported record first-quarter results. As a result, HSC raised its full-year 2007 profit guidance to between $2.69 and $2.74 per share. Analysts responded to the company’s bullish guidance by boosting their earnings estimates. HSC has a current dividend yield of 1.4%.

Momentum – Belden CDT, Inc. (NYSE:BDC)

About the Zacks Rank

Since 1988, the Zacks Rank has proven that “Earnings estimate revisions are the most powerful force impacting stock prices.” A $10,000 investment in the Zacks Rank list made in 1988 would now be worth $1.77 million – equivalent to a 31.8% annualized return! During the 2000-2002 bear market, Zacks #1 Rank stocks gained 43.8%, while the S&P 500 tumbled 37.6%. Also note that the Zacks Rank system has just as many Strong Sell recommendations (Rank #5) as Strong Buy recommendations (Rank #1). Since 1988, Zacks Rank #5 stocks have underperformed the S&P 500 by 143.6% annually (+4.8% vs. +11.8%). Thus, the Zacks Rank system allows investors to truly manage portfolio trading effectively.

Zacks Rank performance is the total return (price changes + dividends) of equal weighted portfolios, consisting of those stocks with the indicated Zacks Rank, assuming zero transaction costs. These returns are not the result of a backtest; these are actual returns since 1988. The stocks in the Zacks Rank portfolios were available to Zacks clients before the beginning of each month (monthly rebalancing). Performance results from 1988 through September 2006 are based on a subset of all Zacks Rank stocks that excludes stocks covered by only one analyst and ADR’s.
