Upon Further Review:

Advanced Micro Devices: Advanced Micro Devices (NYSE:AMD) is moving higher today after the semiconductor firm set a goal for itself of capturing 30 percent of global market share by 2009. Currently, the company's market share is in the low 20s. Separately, Bear Stearns upgraded the shares to "outperform" from "peer perform." Today's rally has taken the shares more than six percent higher. AMD has gained ground during the past few weeks; last week, the stock overtook the 22.50 level, which marks the site of peak call open interest in the September series. This front-month strike is currently home to almost 16,700 open positions. Ranking second in the series is the still out-of-the-money 25 strike, where more than 11,000 open calls reside. The 25 level is also significant from a technical standpoint, as AMD's descending 80-day moving average is descending into this region. So far today, the stock has failed to clear this threshold.

Candela: Medical-equipment concern Candela (NASDAQ:CLZR) visited the earnings confessional last night and reported earnings that fell far short of the mark expected by analysts. In response, Cowen downgraded the shares this morning to "neutral" from "outperform." Today, this stock is one of the biggest percentage losers on the Nasdaq, shedding more than 28 percent of its value. A potential bastion of support resides at the 10 level. Not only is this the psychologically significant barrier between single- and double-digit territory, but it contained significant downside in the shares throughout 2004 and 2005. What's more, 10 marks the sport of the stock's 50-month moving average, below which CLZR has not traded since January 2003.

Toll Brothers: This morning, Toll Brothers (NYSE:TOL) reduced its earnings outlook for 2006, but its third-quarter results did exceed Wall Street's consensus estimate. Investors are focusing on the here-and-now, sending the stock more than four percent higher in midday trading on Tuesday. TOL has been in decline mode since July 2005, surrendering nearly 60 percent of its value beneath the taut resistance of its 10-month moving average. This menacing trendline is perched near the 30 mark, which is also the site of peak front-month call support. The September 30 strike is presently home to more than 23,000 calls. The combination of trendline and options-related resistance could keep TOL from capitalizing on today's strength during the short term.

XM Satellite Radio: XM Satellite Radio (NASDAQ:XMSR) is broadcasting some good news today after Bear Stearns boosted its rating on the stock to "outperform" from "underperform," citing the possibility of a turnaround in the shares. The stock is recovering by leaping more than 13 percent higher. This move has enabled the shares to edge above their critical 10-week moving average, above which XMSR has not managed a weekly close since mid-April. What's more, a single-day rally of 13 percent could be enough to scare away some XMSR short sellers. With more than 16 percent of the stock's float currently sold short, a short-covering rally could be the next step in the equity's near-term recovery.
