S&P 500 Sector Rebounds, Investors Bet on End of Bear Market.

Healthcare has "suddenly come to life," according to Fundstrat's head of technical strategy Mark Newton, who sees a "steep ascent" in the sector's relative chart versus the S&P 500. Healthcare is the second-largest sector in the S&P 500 by market capitalization at nearly 12%, and larger than financials, making it a good sign for market bulls. Medical devices broke out as a subindustry group on Wednesday, and biotech is setting up for something similar, said the strategist. Meanwhile, stock futures are on the fence as a Fed decision nears.
