US equity markets mixed following the first full trading session since last Thursday's Thanksgiving holiday albeit all three benchmark indices hit fresh record intraday highs - Dow up +23-points or +0.10% (touching a record intra-day high of 23,638.92), while the broader S&P500 slipped -0.04% and the technology-centric NASDAQ -0.16%. Retail stocks were again in focus as the holiday shopping season continued and with Cyber Monday sales expected to set an on-line sales record. Investors will also watch for developments surrounding the Republican tax plan, with a Senate vote on proposed tax changes expected this weekâperhaps as early as Tuesday.
