Fitbit getting a nice boost Monday afternoon, after Barclays upgraded the stock to "overweight" from "equal-weight."
The San Francisco-based maker of wearable health and fitness devices cited valuation after the stock dropped nearly 30 percent in the past month.
General Dynamics also received an upgrade from Barclays Monday. While the firm cited valuation as a driver, it also noted the aerospace and defense company had the best "risk-reward profile" in its industry.
General Dynamics is the fifth largest defense contractor based on revenues.
Finally, Philip Morris got a slight upgrade at Nomura to "neutral" from "reduce." The firm noted encouraging industry volume and "reduced risk" products for the American cigarette and tobacco company.
Philip Morris products are sold in over 200 countries and 15 percent of the international cigarette market is outside the United States. Brands include Marlboro, Parliament and Virginia Slims.
