On Friday American Movil (AMX) shares shot up +5.03% on news that AT&T (T) was selling its considerable stake in the company to AMX Chairman and Founder Carlos Slim. 

 I bought American Movil for my Clients in early June as I was able to discover this in my research 

Thanks to the FCC-mandated, government-sponsored program, called LifeLine Assistance, the financially disadvantaged can receive a free government cell phone and up to 250 free minutes and texts every month, although some programs in some states provide even more (a few less). An estimated 15 million other Americans already participate, and tens of millions more qualify to enroll. With the economy falling further and further behind, more and more Americans are finding themselves eligible for the Lifeline phone service program. This is the service that gets the lions share of the business https://www.safelinkwireless.com/Enrollment/Safelink/en/Public/NewHome.html?PromoCode=digital12  and this service in owned by Mexican Billionaire Carlos Slim's American Movil, which is a Mexican based company with 272 million cell phone customers in the USA, Central and South America (They have more subscribers than Sprint(S), Verizon (VZ) & AT&T combined).

American Movil stock was trading for $33.87 in 2007, so I was able to buy it at -39.87% below its all time high. They sell the popular "No Contract" Trac Phone, which has 18 million customers in the USA alone. American Movil is the worlds fourth largest mobile phone company. 

Here is my firms research on American Movil, which shows that it still has a lot of room to go to the upside and shows that Carlos Slim is rushing to buy AT&T's shares as he knows he is getting a bargain.
