Stock prices were up sharply today as March manufacturing activity in both the U.S. and China exceeded expectations.

The good economic news sent interest rates soaring, with the yield on the 10-year Treasury bond rising more than nine basis points to 2.51 percent. It also sparked a surge in the stock indexes. The Dow and S&P 500 indexes were up 1.27 percent and 1.16 percent respectively while the Nasdaq Composite index rose 1.29 percent.

The Entrepreneur Index™ gained 1.3 percent with Wynn Resorts and technology stocks leading the way.

Casino-operator Wynn Resorts was up a heady 8.4 percent -- the biggest gain on the Entrepreneur Index™ today. The stock was buoyed by official and private surveys that showed March manufacturing activity in China expanded at its fastest pace in eight months. Meanwhile, gambling revenues last month in Macau, where Wynn derives about 70 percent of its revenues, also held up much better than analyst expectations. The stock is up 30.8 percent so far this year.
