    Pigs Get Slaughtered It's OK to Pay the Taxes Don't Buy All at Once Buy Damaged Stocks Diversify to Control Risk Do Your Homework Don't Panic Buy Best-of-Breed Defend Some Stocks Don't Bet on Bad Stocks Don't Own Too Many Names Cash Is for Winners No Woulda, Shoulda, Couldas Expect Corrections Watch Bonds Don't Subsidize Losers Check Hope at the Door Be Flexible Quit When Execs Do Patience Is a Virtue Be a TV Critic When to Wait 30 Days Beware Stock Hype Explain Your Picks

I like to end every television and radio show I have with this signoff: "There is always a bull market somewhere, and I will try to find it for you." I say that because it's true.

Something

is

always

working

! Maybe it's gold, so you buy best-of-breed

Newmont Mining

(NEM) - Get Report

. Maybe it's oil, so you buy some

Halliburton

(HAL) - Get Report

. Maybe it's the chemical complex, so you pick up some

Dow Chemical

(DOW) - Get Report

. I've seen moments where the only stocks in bull mode were in your supermarket or your medicine chest, stocks like

Anheuser-Busch

(BUD) - Get Report

and

PepsiCo

(PEP) - Get Report

.

Now, I know that might mean you have to do some trading. It might mean that you may have to look further and harder than your time and your inclination allow. That's OK, too. What matters is that you don't simply default to what's in bear mode because you are time-constrained or intellectually lazy.

This is not just a criticism of do-it-yourselfers. Many professionals stuck with the

complex or the

(NOVL)

/

leg irons long after they should have. If they looked around, they might have spotted the bull market in oil, and bought something as simple as

Exxon Mobil

(XOM) - Get Report

or as complex but rewarding as

Ultra Pete

(UPL)

.

Just remember:

There is always a bull market somewhere.

I will always end my shows with this tag line because it is vital for me to get you to think more opportunistically than the average investor does.

Oh, and by the way, it has the added advantage of being true. For 25 years there has always been a sector that works. You just have to find it. I know it, and I am honored if you will let me help you.

At the time of publication, Cramer was long Halliburton.
