TORONTO, Nov 6 (Reuters) - The Toronto Stock Exchange’s main index dropped more than 3 percent on Thursday as energy and materials issues fell along with commodity prices, which were pressured by worries about a faltering world economy.

The market got a brief respite this week from the U.S. presidential election, rising 4 percent on Tuesday, but that rally faded quickly as the main index turn lower in both following sessions.
“Now the focus is turning to the earnings story and the market, frankly, doesn’t much like what it’s seeing. The earnings story is looking quite gloomy and the markets are taking a big dive on that,” said Elvis Picardo, an analyst and strategist at Global Securities.
“All the data points we’ve been getting in recent weeks have been quite gloomy, not so much in Canada but in the U.S. There’s obviously a tremendous amount of concern about what a global recession would do to corporate earnings all over the world including here in Canada,” Picardo said.
The financial group fell 0.4 percent as brokerages Canaccord Capital CCI.TO and GMP Capital Trust GMP_u.TO reported weaker quarterly results because of market volatility. [ID:nN06412806]
Canaccord was down 9.3 percent at C$5.76, while GMP finished up 1.8 percent at C$5.01.
Manulife Financial (MFC.TO) slipped 1.7 percent to C$25.35. Earlier, the big insurer reported lower quarterly profit but said it was able to get financing to shore up its regulatory capital position. [ID:nN06299759]
