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

Should I ring the register on Wells Fargo (WFC) - Get Report?-- Michael from Florida

Jim Cramer

: The company reported strong first quarter results this week and remains one of the premier financial brands. Early signs from this quarter seem to show that the top banks have found a way to cope with higher interest rates.

I used to own this stock in my

ActionAlerts PLUS charitable trust portfolio, and now I'm beginning to question if I sold Wells too soon.

I own Advanced Micro Devices (AMD) - Get Report, Peabody Energy (BTU) - Get Report, General Electric (GE) - Get Report, Fluor (FLR) - Get Report and Toyota (TM) - Get Report. Am I diversified? -- Andy from New York

Jim Cramer

: You own a share-taking chipmaker, a coal stock, a giant conglomerate (which I ultimately work for, by way of

CNBC

), a construction firm and an automaker. Yes, you are diversified!

What is your opinion of Dow Chemical (DOW) - Get Report?-- Janice from Michigan

Jim Cramer

: In my opinion, the stock is attractive to purchase down around its 52-week low. The company should be a beneficiary of the recent decline in natural gas prices.
