The global economy is rebounding, which means now would be a good time to be overweight stocks versus bonds, says New York University economist Nouriel Roubini.

Bloomberg asked the man who earned the nickname "Dr. Doom" for predicting the 2008-09 financial crisis how he would invest $1,000 now.

"First of all, you have to re-diversify it," he said, noting that some of the money should stay in the United States, some should go to Europe and some to emerging markets.

"I would say that gradually long-term interests are going to rise, so you might want to be underweight in bonds," he added.

"The global [economic recovery] is going to occur, so you might want to be marginally overweight in equities."

Roubini says you probably want an underweight position in emerging market stocks. Presumably that's because those countries face economic struggles.

"More positive signals are coming right now from Japan, from the United Kingdom," he explained. So those would be markets to consider.

Roubini takes issue with his nickname, saying he would prefer "Dr. Realist" as an appellation.

"It's not as if I'm a perma-bear. . . . You have to be a realist about what can go right and what can go wrong."

Some other experts are bullish on stocks too.

"This is the best environment for stocks right now," Tim Hayes, chief global investment strategist at Ned Davis Research, told The Wall Street Journal. "You don't have rising interest rates becoming a problem. You don't have inflationary pressures. You do have earnings growth."
