(AP) – Stocks are dropping sharply after the Supreme Court upheld the central provision of President Barack Obama’s health care overhaul, a requirement that almost all Americans carry health insurance. Stocks of major insurance companies fell sharply as analysts sorted through the ruling. Hospital chains rose. Bank stocks were the biggest losers in the market. JPMorgan fell 4 percent after the New York Times reported that its loss from a complex trade could swell to $9 billion.
