Dow Theory Letters
Dow Theory Letters
ACTING: A few days ago a young subscriber asked me, "Russell, you've been dealing with the markets since the late-1940s. This is a strange question, but what is the most important lesson you've learned in all that time?"
I didn't have to think too long. I told him, "The most important lesson I've learned comes from something Freud said. He said, 'Thinking is rehearsing.' What Freud meant was that thinking is no substitute for acting. In this world, in investing, in any field, there is no substitute for taking action."
This brings up another story which illustrates that same theme. J.P. Morgan was "Master of the Universe" back in the 1920's. Morgan belonged to many exclusive and expensive clubs. One day a young man came up to Morgan and said, "Mr. Morgan, I'm sorry to bother you, but I own some stocks that have been acting poorly, and I'm very anxious about these stocks. In fact worrying about those stocks is starting to ruin my health. Yet, I still like the stocks. It's a terrible dilemma. What do you think I should do, sir?"
Without hesitating Morgan said, "Young man, sell to the sleeping point."
The lesson is the same. There's no substitute for acting. In the business of investing or in the business of life, thinking is not going to do it for you. Thinking is just rehearsing. You must learn to act.
That's the single most important lesson that I've learned in this business.
Again, and I've written about this episode before, a very wealthy and successful investor once said to me, "Russell, do you know why stock brokers never become rich in this business?"
I confessed that I didn't know. He explained, "They don't get rich because they never believe their own bullshit."
Again, it's the same lesson. If you want to make money (or get rich) in a bull market, thinking and talking isn't going to do it. You've got to buy stocks. Brokers never do that. Do you know one broker who has?
A painful lesson. Back in 1991 when we had a perfect opportunity, we could have ended Saddam Hussein's career, and we could have done it with ease. But those in command, for political reasons, didn't want to face the adverse publicity of taking additional US casualties. So we stopped short, and Saddam was home free. We were afraid to act. And now we're dealing with that failure to act with another and messier war.
In my own life many of the mistakes I've made have come because I forgot or ignored the "acting lesson". Thinking is rehearsing, and I was rehearsing instead of acting. Bad marriages, bad investments, lost opportunities, bad business decisions -- all made worse because we fail for any number of reasons to act.
The reasons to act are almost always better than the reasons you can think up not to act. If you, my dear subscribers, can understand the meaning of what is expressed in this one sentence, then believe me, you've learned a most valuable lesson. It's a lesson that has saved my life many times. And I mean, literally -- it's a lesson that has saved my life.

Interviews -- Get out! Get out! Whoever you are! - MSN Money
Part of the premise of your theory is that the Dow Jones Industrial Average and the Dow Jones Transportation Index should move in tandem to confirm each other's new highs or new lows. What does that tell you?
The industrial average reflects the industrial capacity of the nation, the ability to produce goods. The transportation average basically reflects shipping, travel and movement of goods. The thesis is that if you produce, but you're not selling, you're in trouble; and if you're selling a lot, but you haven't got the production behind you, you're in trouble. The Dow Theory requires that the two averages move in harmony, both on the upside and the downside, and when they do that, the moves are considered valid.
The real basis of Dow Theory is values. Beyond that, according to the Dow Theory and according to observations first put forth by Charles Dow back at the turn of the century, the market makes a long trip on the upside of the bull market, and usually yields on the Dow drop down to 3% or below.

XPath select distinct keys generate id...
p2p.wrox.com Forums - Renderering a browser support table
I think for deep understanding of keys and variables it'll be better to refer to Michael Kay's "XSLT Programmer's reference"(it's an excellent source for XSLT in general), or you can look at the W3C's XSLT 1.0 specification: http://www.w3.org/TR/xslt
;
another online snippet on keys: http://saxon.sourceforge.net/saxon6.5.2/xsl-elements.html#xsl:key
I'll try to explain the point concerned with the grouping technique(well known Muenchian method).
The XPath expression
$all-agents[generate-id(.) = generate-id(key('platform', @platform)[1])]
actually selects all such "user-agent" elements, which have distinct "platform" attribute value(and each of those "user-agent" elements is the first one(in document order) in its respective group). Look how it's going on: generate-id(node) function returns a unique id(string) for the parameter-node; key('platform', @platform)
selects all "user-agent" elements having the same value for "platform" attribute as the context node's "platform" attribute; then we select the first one among them(the predicate [1]) and finally we use the function generate-id() to test wheather the context node is the first "representative" of the group or not, and if so, select it. As a result, the XPath above returns "representatives" of groups(each group consists of "user-agent" elements having the same value for the attribute "platform").
For further clarifications see http://www.jenitennison.com/xslt/grouping/muenchian.html
Keys make XPath expression evaluation more effective; they are similar to indexes in relational databases.

And what if I didn?t use attributes? If I was about to select distinct element based upon their names (local-name)? Would that complicate things?
--------------------------------------------------------------------------------
No, in this concrete situation you'll just need to slightly change the code. When you'll fully understand the concept of "key", it'll be obvious.
