Downgrade, Price-Target Cuts Drag Struggling Comcast Shares

Comcast Corp (NASDAQ:CMCSA) shares are down 2.6% to trade at $21.56 after KeyBanc downgraded the stock to "underweight," with an $18 price target. The analyst in coverage cited a downturn in theme parks and subscribers. Though the company's plan to separate from NBCUniversal isn't helping either. Citigroup trimmed its price target to $27.50 to $30 as well.

The stock is a chip shot from its July 24 12-year low of $21.28.  Today's move lower is part of a bigger downtrend, with shares down 27% year over year. The 10-day moving average looms overhead as CMCSA trades near July lows. The stock sports a 14-day Relative Strength Index (RSI) of 25 -- in "oversold" territory, suggesting a short-term bounce may be in the cards.

Given the 12-month deficit, the 10 brokerages with "strong buy" ratings could adjust their stance, which could weigh on CMCSA. Plus, the consensus 12-month price target of $30.03 is a 38.3% premium from the stock's current perch.

Despite the broader sentiment, it should be worth noting CMSCA's Schaeffer's Volatility Scorecard (SVS) sits at a relatively high 85 out of 100, indicating Comcast stock has tended to exceed option traders' volatility expectations during the past year.
