Upon Further Review:

Blackboard: Before the open this morning, Blackboard (NASDAQ:BBBB) boosted its earnings outlook due to stronger-than-expected market demand. The equity gapped higher today, soaring above former resistance at its declining 10-day and 20-day moving averages. What's more, the security's rally has not wavered today despite the market's overall tendency to hover close to the break-even mark. There is a good chance that a sizeable chunk of short sellers are being squeezed out of their bearish bets, creating a short-covering rally for the shares. As of the May report (yes, we're still waiting for June data on NASDAQ stocks), more than five percent of the security's float was sold short, representing potential buying power.

Nokia: Poor, Nokia (NYSE:NOK). Poor, poor, Nokia. The stock more than doubled from its August 2004 low of 11.16, using the steadfast support of its 10-week and 20-week moving average. But it looks like those winning ways are just dreamy nostalgic thoughts at the moment. The stock has dropped below those intermediate-term trendlines and now appears to be hitting resistance at those once-supportive averages. What's more, the equity has dropped below the key 20 level. Meanwhile investors remain extremely optimistic about this one-time high-flier. Call open interest at the July 20 strike sits at more than 25,800 contracts, providing a wall of potential options-related resistance. A rejection at this round-number level would not be out of the question for this laggard.

Tektronix: Tektronix (NYSE:TEK) is one of those stocks that had me scratching my head for a bit today. The company reported earnings that beat the consensus estimate and was upgraded before the open from "hold" to "buy." Yet, at last check, the stock was down roughly eight percent, and that up from its initial loss of more than 16 percent. It seems that investors are focusing on the equity's lowered first-quarter guidance. While today's action is certainly not the most positive, it is heartening to see the shares steadily rebound from their session lows on extremely heavy trading volume. Investors might want to keep an eye on this security. TEK's pullback may be a little overdone.
