Seasonal Investing

This chart shows you that there is some truth to the “Sell in May” and the “Santa Claus” rally. Plus it’s the main reason why I rebalance my 401k on April 30th and October 31st.

I know I posted this before, sometime ago when I was having CMS issues, but I can’t remember when.  Anyway, thanks to Eric for this fantastic script!

  • Judge Rejects Google’s Deal to Digitize Books – NYTimes.com – The deal would have allowed Google to make millions of out-of-print books broadly available online and to sell access to them, while giving authors and publishers new ways to earn money from digital copies of their works. Yet the deal faced a tidal wave of opposition from Google rivals like Amazon and Microsoft, as well as some academics, authors, legal scholars, states and foreign governments. The Justice Department also opposed the deal, fearing that it would give Google a monopoly over millions of so-called orphan works, books whose right holders are unknown or cannot be found.

The line in the sand

Looks like lots of volume activity around the 1300 level for the S&P500.  That’s the line in the sand, for now.

Now, if only I could figure out how to make the dates appear correctly in the x-axis…

The Secret Life of Pronouns

I’ve been traveling a lot lately and managed to catch up on a bit of reading when I’m crusing at 30,000 feet. On my nook right now is a fascinating book that all text miners should at least browse in a book store. It’s called “The Secret Life of Pronouns,” by  James Pennebaker.

The premise of the book is that your social status, sex, personality, and secret intentions can be determined by analyzing pronouns (I, you, they), artciles (a, an, the), and few other functional words. In the beginning of his research, James used the Liguisitic Inquiry and Word Count (LIWC) program but appears to have modified it with proprietary word dictionaries.

From the surface, LIWC looks similar to the word frequency routine that Rapidminer does in the Process Documents operator, but they went further and added a bit more “intelligence” to the analysis. What they did was roll out a fun servce called Analyze Words. You just enter your Twitter handle, click the button, and it gives you a snapshot into your tweet sentiment.

So how does this work?  I suspect that James and team use their dictionaries to categorize incoming text documents and test against them and for the author’s sex, social status, personality, and sentiment. I’m sure that a lot of “up front” and hard work was done to build these dictionaries.  A lot of “up front” work is the norm with text mining and if you try using short cuts, you’ll likely get crappy models.

I think a model like his can be done quite easily in Rapidminer, especially if you build a good crawling and sentiment system to test against. All that it requires is a bit of thought and the will to do it.  Isn’t the data driven world we live in, cool?

Finally!

I think I finally got all the hacker code cleared from this site. What a terrible, time consuming mess!

The next steps is to get Google to check if I’m still hosting any malware.

Thanks for your patience.
