CNBC veteran Ron Insana has rejoined the network as a senior analyst. Insana's first appearance was during today's Power Lunch.

"Look who's back?" said Bill Griffeth, "Ron Insana."

"Seems like an interesting time to get back into the market," said Insana, adding, "Most of my timing over the last three years has not entirely been in my control."

Insana left a primary anchor slot on the network in 2006, for a senior analyst role while also forming Insana Capital Partners. Insana Partners ceased operations in August 2008 when Insana joined a Connecticut-based hedge fund. That move precluded him from appearing on CNBC.

And it appears CNBCers are happy to have him back. During a tease of his segment, Insana got a "Whoo-hoo! Yay" from Power Lunch co-co-co-anchor Michelle Caruso-Cabrera.
