What is your take on the recent IPO of Sealy (ZZ) ?-- Anonymous

Jim Cramer

: I believe the nation's leading mattress maker, which went public last week at $16 a share, remains attractive to purchase below $18. The company can likely earn more than $1 a share in 2007, is paying down debt and will likely initiate a cash dividend over the coming quarters. With that in mind, I believe Sealy can eventually trade up toward $20 a share.

What exactly does the volume indicator at the bottom of a stock chart represent?-- Austin from Indiana
