[BRIEFING.COM] This afternoon's action remains largely listless as the major equity averages continue to dance along the neutral line. Still, that has helped the S&P 500 keep intact its week-to-date gain of more than 2%.

The Nasdaq 100 is sporting a bit of an edge over the headline indices, however. It is currently up 0.4% amid gains by Amazon.com (AMZN 126.00, +5.39). Shares of the online retailer recently received an analyst upgrade.
