Gold continues to show weakness, a combined effect of a slight strengthening of the dollar in four of the five sessions of this week's trading. But something else seems to be going on here even more telling and more interesting if you have gold in your portfolio or are considering adding it:

The trade just looks tired and crowded.

What do I mean by this? Well, when I was trading in the oil pits, sometimes we'd look around at the other traders surrounding us and realize that we all had pretty much the same opinion of the market and the same position.

That would be a dangerous moment, because unless we found some fresh money to come in and share our opinion with us, we'd all be looking to liquidate at the same time, "climbing" over each other and competing against each other. The feeling is like being in a soon-to-be sinking ship with only one porthole in the wall -- sooner or later, there would be an incredible scramble to jump through that porthole but not a lot of free space. Last guy out loses.

That's a crowded trade.

Crowded trades can occur with tens of thousands of traders in a larger market too, if they share the same opinions at one time. A little of that seems to be affecting the gold market in the last week. Even talk of a small slackening of inflation has eased buying in the gold market and allowed it to slip quite a bit, from last Friday's close in the

of $93.71. It's at $92.40 at 3 p.m. Friday.

But the inflation thesis still dominates my view on gold, and every time the trade takes a breath because of temporary dollar strength or just plain tiredness, I'm inclined to wade in for a few more.

Take the opportunity then with this downturn to slowly add to your gold position, or even start to accumulate a little.

Everyone should have a little gold as an inflation hedge, in my view, along with TIPS (Treasury Inflation-Protected Securities) with the monetary environment were in.

Oil continues to succumb to the "endless bid," which I have been writing about and appearing on in videos here on

TheStreet.com

and on

CNBC

to explain.

I'll continue to talk about this in my regular column on Tuesdays, but for trading and portfolio positioning, I believe that oil is operating on the "greater fool" theory and not worthy of investment here, if you don't already have it. That doesn't mean, of course, that it can't move higher. The strength of the endless bid is enormous. But I'd much rather talk about commodities with relation to value as opposed to trying to fathom investor appetites -- a much more difficult game, as if trading weren't difficult enough.

Instead, concentrate on natural gas and stocks related to natural gas.

It is impossible in the long term for oil to continue to maintain its $70-plus-a-barrel price and continue to see natural gas languish at $4 an mmBTU. Although it's surprised everyone and done an excellent job of that so far this year! Crude oil settled down 64 cents to $72.04 on Friday.

Still, that's the opportunity at hand -- not overpriced crude, but relatively

underpriced

natural gas.
