McDonald's stock soaring with the first day of the all-day breakfast offering.

FOX Business Network's Jeff Flock reports:

That's the sound of your breakfast cooking and it's not even breakfast time. It's the first day of all-day breakfast at McDonald's all across the U.S.

Karen King is the Chief Field Officer for McDonald's.

(King) "It's a very big day, we have liberated breakfast.  It's a great day for America, a great day for our customers."

McDonald's has been testing all-day breakfast across the country for several months now, the response has been overwhelmingly good.

As they launched all-day breakfast across the U.S., McDonald's stock hit a 52 week high.
