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

Is Costco (COST) a good stock to keep, or should I sell it?

-- Adrian from Texas

Jim Cramer: I maintain that the retailer is attractive to purchase at current levels. The stock is down about 15% from its recent highs, even though management continues to deliver consistent same-store sales growth.

I own Clorox (CLX), Emerson Electric (EMR), America Fundamental Investors Fund (ANCFX) and American New Perspective Fund (ANWPX). How does my portfolio look?

-- Wendy from Illinois

Jim Cramer: While I like Emerson as a stock, you already own it in both of your mutual funds, and probably don't need to hold it as a separate position.
