* Isuzu climbs after raising earnings estimate

TOKYO, April 20 (Reuters) - Japan's Nikkei average clawed up 0.4 percent on Tuesday, a day after its biggest percentage loss in two months, with exporters rising though wariness about tighter financial regulations capped gains.
Carmakers rose, with Isuzu Motors <7202.T> up following an outlook hike and Suzuki Motor <7269.T> gaining after a report that it plans to boost output in India. [
]But gains were limited, with investors still wary after concern about fraud charges against Goldman Sachs Group Inc <GS.N> revived long-term worries about tighter financial regulation, while worry about China's attempts to control its real estate market sent Shanghai shares tumbling.
Market players said the news that U.S. regulators had charged Goldman Sachs with fraud over its handling of a debt product tied to subprime mortgages had mainly been used as an excuse to take profits on Monday.
"The market's taking a bit of a breather today after being sold so sharply yesterday, but it's still hard to predict direction and we can't say the yen is definitely weakening," said Kenichi Hirano, operating officer at Tachibana Securities.
"If the dollar could rise to 93 yen, the mood in the market would really change. But technically, the picture for stocks right now isn't that good."
The benchmark Nikkei <
> gained 46.24 points to 10,955.01 by midday after falling 1.7 percent to 10,908.77 on Monday. The broader Topix < > gained 0.6 percent to 976.69 yen.The Nikkei's 25-day moving average, currently a little above 11,000, is likely to prove short-term resistance.
Initial support lies near 10,800, a roughly 38.2 percent retracement of a two-month rally that started in early February and pushed the Nikkei up to an 18-month peak of 11,408.17 in early April. Below that a 50 percent retracement of that same rise lies roughly around 10,600.
But the benchmark's losses over the past two trading days have sent its relative strength index (RSI) down as far as 48 from a high last week of 76. Anything from 70 and above is considered overbought, while 30 and below is oversold.
"Given that the Nikkei has fallen some 3.2 percent over the last two trading days, investors are likely to buy at first on the sense that prices are now comparatively good, with a halt in the yen's rise boosting exporters," said Hiroichi Nishi, general manager at the equity division of Nikko Cordial Securities.
"But there's a lot of uncertainty out in the international markets, including China's recent steps to control the real estate market, as well as various international meetings."
Beijing ordered local governments on Monday to take steps to control speculative buying of real estate, sending Shanghai shares <
> tumbling nearly 5 percent. [ ]With Japanese corporate earnings results set to move into full gear from next week, the market is growing increasingly attentive to earnings reports and forecasts, though market players warned that high expectations could lead to falls if results were merely in line with forecasts.
Isuzu Motors climbed 5 percent to 275 yen, becoming the top percentage gainer on the Nikkei 225, after the automaker raised its net estimate for the year ended in March to a profit of 8 billion yen ($86.54 million) from a loss of 5 billion yen.
Suzuki gained after the Nikkei business daily reported that it plans to boost engine output capacity in India by about 30 percent to more than 1.25 million units a year by setting up a new line dedicated to low-pollution models.
It rose 1.8 percent to 1,964 yen, outperforming the transport equipment subindex <.ITEQP.T>, which rose 1.2 percent. ($1=92.43 Yen) (Editing by Michael Watson)
