How to make money on news headlines

Three names in the news offer opportunity if you know how to look at them, Hunting Hill Global Capital CIO Adam Guren said Tuesday

"The 'shock response' is really a post-event trading strategy," he said. "We think some of the best trading opportunities happen when you have unanticipated events disrupt some of the historical relationships in the marketplace. So, generally speaking, you can look at a macroeconomic shock. You can look at a corporate action event. You can look at a merger."

On CNBC's "Fast Money," Guren shared three of the stocks which he was trading on recent news: BlackBerry, Cobalt International and Delta Air Lines.

BlackBerry's recent announcement that it would initiate a "strategic review process" was "nothing new," even though the stock traded to a high of $12.18 per share this week, Guren said, making the case for shorting the stock — via puts at the moment.

"If it does get to the $11 or $11.50 range, we'll probably be outright short the stock, depending on the announcement," he added.

Guren said that he was sure to manage risk "because we know that this is a relatively crowded trade."

"There's 33 percent short interest in this name on the float, so it does get squeezed up, we don't want to be shaken out of this thing, and so we're looking to actually short on those squeezes, like I said, again, around $11.50," he added.

Next, he liked Cobalt international, a deepwater offshore-drilling company that announced a production decline, pushing its stock down 15 percent.

"We think this is overdone," Guren said.

With coverage by 16 Wall Street analysts and 16 "buy" ratings on the stock, Guren said he would be a buyer around $25 per share.

Lastly, the pending merger between Delta Airlines and United Air Lines posed an unknown factor because of a U.S. Justice Department review.

"This pending merger, we feel like it doesn't necessarily matter for Delta which way the Department of Justice lands, because Delta is set up in a good way. They have a decent business model. There's a secular shift in this industry. It was beat up last week," he said. "We're an owner here."
