Following on the heels of their poor Black Friday performance, shares of online auctioneer eBay (EBAY: sentiment, chart, options) are offering up a Cyber Monday encore. At last check, EBAY was off nearly 4%, with the shares reeling from negative brokerage comments earlier in the session. Specifically, Stifel cut its price target on the stock to $17 per share from $20 per share. EBAY watchers may remember that the stock was downgraded on Friday at Argus to "hold" from "buy."

It wasn't all bad news for EBAY today, however, as Standard & Poor's Ratings Services assigned its A- corporate credit rating to eBay with a positive outlook. "The rating on eBay reflects its well established brands in Internet e-commerce and payment segments, coupled with strong discretionary cash flow generation and ample liquidity," the ratings agency noted.

Still, the bad has outweighed the good in today's trading, with EBAY falling back below potential resistance at the 13 level. The shares have been rebuffed by a wall of resistance in the 13-14 region during the past 3 weeks, and the situation won't improve as time wears on. Specifically, EBAY's 10-week moving average is quickly descending into the area, and could pressure the shares even lower. The stock has not closed a week above this trendline since mid-May.
