This week, Brian Bolan and Terry Ruffolo discuss CSTM and AAOI. Brian is the aggressive growth stock strategist at Zacks and while CSTM doesn’t have the A for growth that he normally likes to see. Terry gives Brian some guff over having the divergence going in the opposite direction as this stock has an A for value and an F for growth. Brian shows the story of increasing volume and increasing price, which is how it got on his radar screen. Speaking of radar screens, when a company raises guidance four quarters in a row it should be on everyone’s radar. AAOI did just that today, boosting expectations again and that means that even though estimate have increased 20% over the last 90 days, we can expect to see them move higher. AAOI is a Zacks Rank #2 (Buy), as is CSTM, but the increase in guidance should push this stock to a Zacks Rank #1 (Strong Buy).More Stock News: This Is Bigger than the iPhone!It could become the mother of all technological revolutions.
