Citic Securities, Guosen Securites both being investigated

Chinese authorities' investigations into two major Chinese brokerages over suspected violations pressured shares in Shanghai Friday, dragging the market lower for the week.

The Shanghai Composite Index was on track to lose 4% this week, with most of the losses on Friday, when the benchmark fell 4.6%. .

Worries over China's financial-market investigations also weighed on Hong Kong's Hang Seng Index which fell 1.8% on Friday and is on track to lose around 3% for the week.

In Japan, shares fell 0.3% Friday after the Nikkei neared the 20000 level earlier this week. Australia's S&P/ASX 200 fell 0.2% and South Korea's Kospi fell 0.1%.

On Thursday, China's largest stock broker, Citic Securities Co. (600030.SH), said it would cooperate with the country's stock regulator in an investigation of the firm for suspected violation of securities rules. Guosen Securities (002736.SZ) , China's third-largest broker by assets, said it is under investigation for suspected violations, too, according to a company filing.

Shares of Citic fell 6.6% in Shanghai and 4.2% in Hong Kong on Friday. Shares of the Hong Kong-listed Guosen lost 6%.

Shares of Haitong Securities (600837.SH) fell 3.8% in Hong Kong, before the brokerage issued a trading halt after the market opened without citing reasons.

Chinese authorities' increased scrutiny of the securities industry is part of a crackdown that has ranged from targeting "malicious" short sellers to arresting star fund managers in the wake of the summer stock rout. The Shanghai Composite Index, which fell more than 40% from peak to trough during the summer, is now up more than 20% from its August lows.

Analysts say officials' moves aim to drain leverage and speculation from the market. Investors who borrowed heavily to buy shares fed a yearlong rally through June, though the unwinding of those loans also accelerated losses over the summer.

A two-month rebound in margin loans has stalled recently with loans reaching 1.22 trillion yuan ($190.94 billion) as of Thursday, according to Wind Information Co.

Loans fell below 1 trillion yuan in late September, when the market's fall forced the unwinding of bets by brokerages.

Regulators also have said they are looking for signs of irregularities in the industry. Earlier this week, the quasi-regulatory Securities Association of China said Citic overstated its swap transactions numbers between April and September.

"The government wants to foster a stock market that can support the real economy, not one that allows speculative investors to profit from derivatives products," said Guotai Junan's analyst Zhang Xin.

Earlier this week, metals including copper and nickel fell to multiyear lows. Metals rebounded Thursday after reports that China will start buying industrial metals to stock up its strategic reserves.

Still, the materials sector on the Hang Seng and Australia's S&P/ASX 200 indexes is down 3.6% and 4.5% this week, respectively.

The broader S&P/ASX 200 is down 1.1% week-to-date, after jumping 4.1% the previous week, its best week in over a month.

In Japan, a weakening yen lifted the Nikkei close to the 20000 level earlier this week, though shares retreated Friday. The yen was last at Yen122.59 to one U.S. dollar, roughly flat from late Thursday in Asia.

The currency has weakened since mid-October, when it reached as strong as Yen118.04 to one U.S. dollar. A weaker local currency bodes well for Japanese exporters that repatriate profits from abroad.

Investors are also hopeful that Japan's central bank will extend stimulus, after minutes show officials are open to further action if inflation targets slip out of reach.

On Friday, data showed that consumer prices in Japan fell slightly for the third month in a row in October. The figures indicated that sustained inflation remains elusive despite the central bank's efforts to spark price growth. Some economists have forecast that flat lining inflation may force the bank and some of its peers to ease again.

Markets in the U.S. were closed Thursday for the Thanksgiving holiday.
