As shown, Technology is still on top with a weighting of 19.87%. Tech has been the largest sector throughout the entire bull market, but it has been stable around or just below the 20% mark the entire time. The Financial sector ranks second with a weighting of 16.14%, followed by Health Care at 14.94% and then Consumer Discretionary at 12.56%.
