TORONTO, Sept 28 (Reuters) - Canada's main stock index
plunged on Monday, with drugmaker Valeant Pharmaceutical
International VRX.TO stunned by U.S. congressional rebuke and
global malaise hurting a range of Canadian resource companies as
commodities prices fell.
Shares of Valeant, a major weight on the index, fell 16.3
percent to C$221.81 after Democratic lawmakers attacked
"massive" price increases for two heart drugs after the company
bought them in February.
While Valeant's fall was by far the biggest reason for the
day's decline, a range of financial and resource-related stocks
- the index's biggest groups - also fell amid unease over the
economic health of China and other big emerging markets.
"People are still blaming global growth, China. But I think
it's now beyond that," said Allan Small, a senior investment
adviser at HollisWealth. "I think it's now just this overall
feeling of negativity in these markets."
