The end of the longest government shutdown in history is doing little to gas up stocks this afternoon. The Dow Jones Industrial Average (DJI) is down over 300 points, cooling from yesterday's record close, as investors continue to rotate out of tech stocks. The S&P 500 Index (SPX) and Nasdaq Composite (IXIC) are sharply lower as well, the former weighing the latest earnings reports and the latter carrying a triple-digit deficit as concerns over AI companies' valuations linger. 

Cisco Systems Inc (Nasdaq: CSCO) stock is up 4% to trade at $76.92 at last check, and earlier surged to a record high of $79.50 after the tech name reported better-than-expected fiscal first-quarter results. Plus, the company hiked its upbeat 2026 guidance amid strong AI demand. Cisco Systems stock is is attracting unusual options activity today, with 113,000 and 56,000 puts exchanged so far, which is six times the volume typically seen at this point. Most active is the weekly 11/14 80-strike call, where new positions are being opened. CSCO is up roughly 30% so far this year. 

The shares of Biogen Inc (Nasdaq: BIIB) are among the SPX's outperformers today, last seen up 3.5% to trade at $167.24. The equity is on track for its fourth-straight daily gain, after earlier securing a fresh 52-week high of $167.67. BIIB yesterday conquered $60, too, after facing rejection at that level in early October. In the last six months, BIIB added more than 35%.

Robinhood Markets Inc (Nasdaq: HOOD) stock is toward the bottom of the SPX, down 7% to trade at $123.73. A familiar floor at the $120 level, which kept pullbacks in late September and October in check, is set to contain today's losses. The equity is not too far removed from its Oct. 6, all-time high of $153.86, and sports a massive 286.5% year-over-year lead.
