Diamond Resorts International's shares were lifted after the hospitality company announced it would explore "strategic alternatives to maximize shareholder values." Though the company has created "intrinsic value," the board said in a statement, shares are down almost 43 percent so far this year.
IMAX's stock fell after posting lower-than-predicted earnings in the fourth quarter. The immersive movie technology company reported earnings of 39 cents per share, excluding items, lower than the 43 cents per share estimated by Thomson Reuters analysts. Still, with major movie franchises releasing sequels this year, the company is "well positioned" going forward, IMAX CEO Richard Gelfond said in a statement.
And Bankrate, an online aggregation website of personal finance information, saw shares dive nearly 30 percent in somewhat light trading volume after competition from Google and lower advertising revenue depressed earnings. The company said Google will terminate its rival credit-card comparison tool, but management is still assessing the impact of lower advertising budgets in the winter season, said Kenneth Esterow, president and CEO of Bankrate, in a statement.
"In 2016, RATE will step up product, technology and marketing investments," Esterow said. "We are confident these investments are the key to return Bankrate to the level of growth that we all expect, in 2017 and beyond."
