No,

Nymex

(NMX)

isn't nuts. Not at all. Of course, this could be a little like the

New York Stock Exchange

(NYX)

in that the first few days its stock traded were nutty and then it went down and stayed down for a while because it made the Euronext bid. I don't think there's anything Nymex will turn around and buy right now, so you're safe from that risk.

We're all so revolted by what happened in dot-com land (

remember?) that we want to say "this is all baloney." I don't like that analysis. What that analysis says is that there was a stampede toward something worthless and we went and bought the worthless tulip, a la the Dutch bubble, hoping someone else would be even more stupid and buy it from us.

That's not the case here. This is more the case of saying, "OK, had I bought

CME

up 100% from where it came public, I still would have made great money." The comp is fantastic here. Plus the underwriters knew that the demand was much greater than this and they

want

you to make money. They aren't, unlike during the dot-com period, trying to get one over on you!

I urge you to think like this: Let's say the underwriters issued three times as many shares as they did at $19, and the stock opened at $44. Would you freak out? Maybe less than you are now. It still would be huge, but wouldn't seem as nutty to you.

Bottom line: I had said to let Nymex open and then buy it down. I didn't think it would open

this high. If I wanted 500 shares, I'd buy 125 right now.

Then I'd wait to buy more -- not today, not Monday, but a week from now. If in a week it's above where it's trading today, I'd buy 125 shares, and if it's below, I'd buy 125 shares. Then, if after I'd made my 125-share buy, it still was above, I'd call it a day. If it still was below, I'd keep buying until I got to 500 shares, using 10-point increments down.

If worse comes to worse, you'll have 250 shares of what will be a great stock of a great company. There are only so many exchanges. They have fabulous barriers to entry. You can ride this one as it raises fees and becomes more profit-oriented. And as wacky as it seems, it will work for you.
