TOKYO, Aug 6 Japan's Nikkei share average is likely to lose ground for the second day in a row on Tuesday on the yen's strength against the dollar, while most investors are expected to hug the sidelines due to the summer lull and lack of market-moving catalysts. Market players said the Nikkei was likely to trade between 14,150 to 14,350 during the session after falling 1.4 percent to 14,258.04 on Monday, giving up some of its 5.8 percent rise over the previous two sessions. Nikkei futures in Chicago closed at 14,250, up 0.1 percent from the close in Osaka of 14,230. Investors are expected to remain focused on the earnings season for direction. Corporate earnings from companies such as Isuzu Motor Motors Ltd and Suntory Beverage & Food are expected on Tuesday. "Thin trading volume will likely add to investors' concern. It's due to the summer doldrums," said Hiroichi Nishi, an assistant general manager at SMBC Nikko Securities. "We may not see huge selling in the cash market, but if trading volume is thin, the market is likely to be swayed by futures trading." On Monday, volume for both the Nikkei and the Topix was the lowest since December 2012. For the Topix, only 1.99 billion shares changed hands, falling below 2.0 billion shares for the first time since December and was down 23 percent from last week's average daily volume of 2.6 billion shares. Analysts also expect Wall Street's fall overnight to dampen buying interest, while the U.S dollar's pullback against the yen is expected to hamper exporters. A rise in the yen hurts Japanese exporters' competitiveness overseas as well as their earnings when repatriated. The dollar fell 0.6 percent to 98.31 yen overnight, and was last traded at 98.33 yen. > Dow, S&P slip from record highs on year's lowest volume > Dollar falls vs yen on uncertainty about Fed > Bonds fall on strong service data, upcoming supply > Gold drops on strong U.S. and UK economic data > Oil ends touch lower; upbeat US data offsets supply recovery STOCKS TO WATCH --Sony Corp Sony's board voted unanimously not to sell its entertainment unit, rejecting a proposal from hedge fund manager Daniel Loeb, the company said in a statement on Monday. --Toshiba Corp Toshiba plans to build a memory chip production factory with a total investment of 400 billion yen (about $4 billion) with SanDisk Corp SNDK.O, the Nikkei reported.
