Shares in the outfit soared more than 10 percent after the Nikkei Business Daily reported that Sharp forecasts operating profit of about $385 million for the business year through March which was much better than expected.
Meeting the forecast would mark the first operating profit in three years for Sharp, which is rebuilding under Taiwan's Foxconn which bought two-thirds of the telly maker in August.
Sharp slashed about 6,000 jobs in the last financial year through early retirement and an operations overhaul including withdrawal from its money-losing North American TV set business.
Sharp said it expected profit to improve but revenue to fall. Its shares subsequently jumped nearly 11 percent to their highest price in about six months, far outperforming the benchmark Nikkei average share price index.
However the prospects of Sharp's mainstay display panel business are not that hot. The global panel market is on the cusp of improvement as a production cutback resolved a supply glut.
But Sharp still has to find ways to compete with Chinese peers rapidly expanding capacity, and with South Korean makers far ahead in next-generation technology.
Sharp said it would provide a full-year earnings forecast on 1 November when it announces its second-quarter results.
