Contest Begins Tomorrow

January 31, 2007’s $100 Contributor-of-the-Day Contest begins tomorrow. We are giving away $100 every weekday in February to the best wiki contributor.

Login to ValueWiki (it’s free), search for any stock in the US, Canada, or Australia, and start writing. It’s just like Wikipedia where anyone can edit. We will announce the first winner, here on the blog, tomorrow, Thursday, by 11:59 EST.

If a blogger wins, we will feature your blog in that post as well. So you will get site exposure and $100. Thank you to Micki at WorldChanging, TradingGoddess, and all the other blogs who have covered the ValueWiki contest. It is much appreciated.


Deep – Data Mining and Technical Analysis

January 31, 2007

So I once spent a whole month data mining the Dow. I learned that sunny days in Manhattan outperform cloudy days. Mondays outperform Fridays. The 3rd quarter is typically dismal, and the 4th quarter is historically the best. So if you conglomerate this data and leverage the Dow Diamonds, you can theoretically make money by buying Dow calls on a sunny Monday in November, right? I’m not sure if anyone’s ever had the guts to start a sunny-day-hedge-fund, but I would be very interested to hear the results!

Anyone interested in technical analysis and data mining should check out this fascinating site, You can examine correlations between stocks – in tandem or apart. You can even study seasonal analysis – what historically is the best day of the year to buy Google? (Answer – August 20 averages 6.73%). I have no idea how Eric Cahoon has built these data mining tools – he must be some kind of genius. If you don’t know Deep Market, go check it out, play with the tools, and read Eric’s daily blog. Big thumbs up.

Bubbles are Not Inflationary

January 31, 2007

Rumors are afoot of a web 2.0 bubble, which raises a sore point for me. People believe that bubbles are inflationary. From 1999 to 2000, the much-lauded Alan Greenspan raised interest rates six times in an effort to tame “irrational exuberance” and stave off inflation. The sixth interest rate hike sparked the crash of April, 2000, ending the longest peace time economic expansion in US history. Greenspan’s subsequent interest rate reversals then fueled the housing bubble, a fact which the now retired Greenspan has admitted.

The point I want to make here is, academically, a stock market bubble is not inflationary. This is a difficult point to articulate, so follow me like a leopard…

Let’s say I take my company public, selling 10 shares for $1 each. Zach (the public) buys all 10 shares for $1. Zach spent $10 and Jon got $10. Net change in dollars in the economy = zero.

Now let’s say there’s some “irrational exuberance.” Bob buys 1 share of Zach’s stock for $10. Now Zach has $10 and Jon has his $10. And Bob spent $10 and Zach spent $10. Net change = zero.

Let’s say Bob goes ape, and buys all remaining shares for $100 bucks a pop. Zach now has $910 and Jon has $10. Zach spent $10 and Bob spent $910. Net change = zero. The amount of real money in the economy doesn’t change! Just because there are millionaires-on-paper does not mean there is any change in real dollars in the economy.

Yes, there was irrationality when the stock market soared in the 90’s. But there was certainly some irrationality when it crashed, too. Greenspan got a lot of praise for being fortunate enough to preside over a technology boom and an economic expansion. But for a guy famous for the “soft landing” philosophy, he sure created a hard bump in 2000, precipitated the recessession of 2001-2002, and helped to create the housing bubble. Is that fair to say?

Maybe I’m being a bit harsh on Greenspan. I certainly couldn’t have done a better job! But I’ve always been intrigued at the disconnect between the media’s high opinion of Greenspan’s Fed performance, and opinions of those of us in the finance world.

Is Wikipedia Becoming a Totalitarian State?

January 31, 2007

Seeing as I’m a co-founder of ValueWiki, it’s probably no shocker that I’m a Wikipedian. And say what you will, but I think Wikipedia is one of the greatest accomplishments of the internet. But is Wikipedia becoming totalitarian?

In addition to recent battles with Microsoft, Wikipedia is in the final rounds of stamping out Esperanza. Esperanza is a Wikipedia subculture that evolved to inspire a sense of community among Wikipedians. The group created “coffee lounge” chat pages, mentored new members, compiled birthday calendars, and awarded “Barnstars” to recognize user accomplishments. In a wiki world of vandals and link spammers, Esperanza supported projects like the Kindness Campaign, WikiLove, and the Barnstar awards. They created “Trading Spaces,” where html-savvy users would pimp each other’s bio pages. Through colorful userpages and sig’s, Wikipedia was finally shedding it’s drab communist grey for a more fun and user-friendly feel. And the sense of community and support Esperanza created certainly helped to fuel Wikipedia’s explosive growth.

Unfortunately, Wikipedia admins have decided that Esperanza is non-encyclopedic, and set about snuffing it out the best way they know how – Byzantine beaurocracy! You really have to read this page to believe it. I’m not sure people outside of Wikipedia are aware this is going on. It reminds me of the Chinese government stamping out Falun Gong. What’s the harm in a bunch of people who want to do calisthenics? Or setup birthday calendars on a wiki talkpage?

Alright, I’m a wiki-geek. But it’s a little sad to see neat Wikipedia projects like Wikifun and WikiGames fizzle out. I know of many upset and exhausted Wikipedians who have left. Now users post in the community portal, Is Wikipedia Beginning to Decelerate?

Zach and I are watching and listening. For any Wikipedians who migrate to ValueWiki, we encourage you to start groups, pimp your bio pages, and build a community. Ultimately, we believe a healthy sense of community will build a better wiki.

Top 60 Finance Blogs (and counting…)

January 30, 2007

In a particularly obsessive compulsive post last week, I decided to rank all the finance blogs I read, by Alexa and Technorati rank. To my surprise, several thousand of you came to read the list. Many of you offered good suggestions for corrections and inclusions. In one week, the list has grown from 40 blogs to 60. I wish I could somehow have invested in this.

Accuracy and Fairness
Alright, alright. So what is the point of this popularity contest? What does Alexa really measure? Is this high school all over again?

A lesson I learned while compiling these numbers is that many of my favorite bloggers are often toiling in obscurity. To this end, I took ten impressive blogs with Alexas over 1 million and blogged Ten Great Finance Blogs Flying Under the Radar. I encourage you to check out any new blogs you haven’t heard of. I wish I could provide similar reviews for all 60 blogs listed below, but what am I your butler? Go check ’em out yourselves!

Including Your Blog
I invite you all to list your finance blog on the ValueWiki Blogroll. It’s a wiki, so anyone can edit. Soon I will post this Alexa list on the ValueWiki website as well, so you can update your stats yourself. In the meantime, you are welcome to post your blog in the comments (including your TR and A ranking is helpful for my updates).

So without further ado…
