The 10 Worst-Performing Stocks on Monday

3. JetBlue Airways Corp. (NASDAQ:JBLU)

JetBlue Airways shares fell 8.21 percent on Monday, closing at $6.04, amid growing uncertainty over its business prospects. The decline followed continued denials from United Airlines regarding rumors of merger talks with JetBlue.

The speculation originated from a social media post by a well-known aviation insider, who has a solid track record of breaking major stories in the industry. According to the social media post citing sources privy to the matter, United Airlines is reportedly setting its sights on JetBlue, although it remained unclear whether the discussions were about a potential merger or an acquisition of assets. United Airlines dismissed those rumors in a filing with the SEC.

In addition, JetBlue traded lower in line with an overall decline in US airline stocks on the back of higher oil prices following President Donald Trump’s hefty tariffs on a range of imports, including crude from Canada and Mexico, threatening higher costs for American consumers.

The US gets most of its oil imports from Canada, as well as about 500,000 barrels a day from Mexico.
