Catch up on the weekend's top five stories with this list compiled by The Fly:

1. Ford (F) plans to build a new assembly plant in Mexico and expand its existing factory near Mexico City, sharply increasing production capacity in the country as it looks to focus its U.S. efforts on trucks and SUVs, the Wall Street Journal reported.

2. GoPro (GPRO) and Microsoft (MSFT) signed a patent licensing agreement late Friday, lifting shares of the action camera maker in after-hours trading.

3. Media reports indicate Twitter (TWTR) could be rethinking its news feed, potentially ordering posts based on popularity rather than chronological date.

4. Apollo Education (APOL) received a second investigative subpoena from California's attorney general related to the marketing, recruiting, accreditation, and other aspects of its for-profit schools.

5. Celgene (CELG), Gilead (GILD), Thermo Fisher (TMO) and Vantiv (VNTV) were mentioned positively by Barron's this weekend, while Church & Dwight (CHD) was called overvalued and GoPro was identified as a possible takeover target by Under Armour (UA) or Sony (SNE).
