Hi, I used Bloomberg Terminal and Excel to pull 'PX_LAST' data of various S&P sectors such as Information Technology, Health Care, Financials, etc. Everything seems fine except some dates like: 4/13/2017 2328.95, 888.68, 854.9, 380.38, 689.2954, 550.91, 563.79, 509.4, 262.15,321.77, 165.32 4/14/2017 2328.95, 888.68, 854.9, 380.38, 689.2954, 550.91, 563.79, 509.4, 262.15,321.77, 165.32 Why would the PX_LAST values be the same for two dates? 4/14/2017 was Friday and I believe the market was open that day. Shouldn't prices change from the day before?
