Editor's Note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EDT on CNBC.

What is your opinion on the drug retailers?-- Joe and Anne Marie from Clinton, N.J.

James J. Cramer

: Here is a three-for.

Walgreen's

(WAG)

and

CVS

(CVS) - Get Report

are best in breed and growing their store bases. I would be buyers of them to play an aging population and an increase in generic drug sales that carry higher margins. And I would be a seller of

Rite Aid

(RAD) - Get Report

, which is struggling with an older store base an a heavy debt burden. I own

UnitedHealth

(UNH) - Get Report

for my Charitable Trust to play the health care sector, though.(To see all of the holdings in my charitable trust, visit

ActionAlertsPLUS.)

What should I do with MNBA (KRB) now that Bank of America (BAC) - Get Report is taking it over?-- Dan from Illinois

James J. Cramer

: We never attempt to do arbitrage on "Mad Money." I would take the bid from Bank of America and sell right into it. I think it is a fool's game to hold off for a higher bid.

What should I do with your previous Stock of the Week, Time Warner (TWX) ?-- Rick from Wisconsin

James J. Cramer

: I like Time Warner here and think it is bargain when you consider the premium the Dolans just agreed to pay per subscriber to take

Cablevision

(CVC)

private. At this price, you are practically getting the AOL division for free, and I think shares trade to $20 a share in the coming year.

What is your opinion of Sirf Technology (SIRF) ?-- Paul from Ottawa

Image placeholder title

James J. Cramer

: Sirf is an emerging player in the global positioning satellite (GPS) space. The company has an established installed base already thanks to its relationships with Motorola and LG, and I expect further adoption of handheld GPS solutions such as GPS in cell phones to lead to 30%-plus top-line growth for Sirf.
