| * Equities have been strong lately, with the S&P 
				ending at records for the past four sessions, and rising in 11 
				of the past 13. While Wall Street's upward trend is still seen 
				as intact, it may be harder to continue notching solid gains in 
				the absence of big catalysts. There are no major economic 
				indicators on tap for Tuesday.
 * Investors continue to watch the level of trading volume, which 
				has been below average of late, potentially making the market 
				more susceptible to big swings. The CBOE Volatility index, which 
				typically moves inversely to the S&P, rose 3.9 percent on Monday 
				despite the market's advance. The "fear index" recently fell to 
				its lowest since February 2007, and remains at levels that are 
				very low from a historical perspective.
 
 * S&P 500 futures fell 3.2 points and were below fair value, a 
				formula that evaluates pricing by taking into account interest 
				rates, dividends and time to expiration on the contract. Dow 
				Jones industrial average futures fell 17 points and Nasdaq 100 
				futures lost 6.25 points. * The benchmark S&P 500 index has 
				advanced 5.6 percent this year, with the strongest group being 
				"low beta" names like utilities, which tend to move less 
				dramatically than the overall market.
 
 * Achillion Pharmaceuticals Inc surged 40 percent to $5.95 in 
				heavy premarket trading, building on a jump of almost 48 percent 
				on Monday. The company early Tuesday commented on an ongoing 
				Phase 1 clinical trial, and was upgraded to "market outperform" 
				from "market perform" by JMP Securities.
 
 * Another volatile name of late, Spherix Inc, rose 13 percent to 
				$1.95 before the bell. Earlier, one of the company's wholly 
				owned subsidiaries said it had commenced patent litigation 
				against Huawei Device USA Inc.
 
 * Microsoft Corp will work with Chinese Internet security 
				specialist Qihoo 360 Technology Co on mobile Internet and 
				artificial intelligence technology, Chinese state media reported 
				late Monday, as the U.S. software giant fights security concerns 
				in the country.
