Hello…

Yahoo! Finance only has data on the Value Line Geometric Average going back to January 11, 1985 – but according to this site, the index dates to June 30, 1961. Winning on Wall Street covers May of 1966 through February of 1993.

Anyone know how I can get my hands on data prior to 1985? Pretty please….

Regards,

Kevin

Sign-in with Facebook now here!

by Kevin on September 29, 2010

kewl

This is gonna be quick – I’m getting ready to head out to a concert. I just added a new feature on the site… the ability to sign-in with Facebook.

Here’s the deal – *no one* wants to have to create another new username/password for every random site they stumble across on the interwebs. So Facebook (and lots of other large web properties) offer themselves as a trusted source of authentication. That means you can use your Facebook credentials to sign into Zweigmodel.com.

A couple of quick notes:

You are signing into Facebook — YOU ARE NOT providing your FB credentials to me. Check out the URL, it’s the FB url. Once FB verifies who you are, they redirect you to my site, and there is a brief handshake between me and FB… something that goes like – “yep, this is a valid Facebook user and here are a few pieces of info about him/her”. It then passes me your first name, last name, email address and a few other pieces of data. I’m not storing them yet… I soon will for tracking/metrics/etc. Don’t worry – 1500 people and not one spam.

I will be adding a few other providers soon… namely, Google, MSN, Yahoo! and OpenID. Between those four (plus Facebook) – I think I’ll have the whole planet covered.

And, for you – there’ll be one less username/password to remember.

QUESTION: Will anyone be impacted by this? Is there anyone who *doesn’t* have credentials with one of those five services? Man, I’ve got all five… and I don’t think I’m alone in that regard.

I’d love to hear your thoughts.

Regards,

Kevin

Finally, Something Visual!

June 7, 2010

Well, I know I said last September about adding something to visually display data. What can I say, I’m lazy. Now, I FINALLY added a very basic  Prime Rate Indicator chart. I was originally doing some pretty cool stuff with Flash, but with all of the static between Apple and Adobe (and the fact that it […]

Hello – I am in currently in the process of migrating from Blogger to WordPress for blog.zweigmodel.com. Blogger is down (again) so I can’t import my older posts from there.

Prime Rate Indicator – Now Configurable

September 18, 2009

The Prime Rate indicator is now configurable. You can change the threshold ‘high/low’ rate (it’s 8% in the book) and you can choose between either the Value Line Composite Index (Geometric), the S&P 500, or the Dow Jones Industrial Average. Interestingly, setting the threshold to 14% shows significantly improved performance over 8%. Hmmm… need to […]

Zweig Model – Status Update & Roadmap

September 16, 2009

Although it may be hard to tell, we’re making some significant progress with the indicators. We’re just about done with making the Prime Rate Indicator configurable (you will get to change the high/low threshold, as well as the Index). Fortunately, it’s starting to look better (from a results/performance perspective – not necessarily a user interface […]

Prime Rate Indicator – Published!

September 7, 2009

Well, it’s been the better part of a year since our last post – but we’ve finally published the Prime Rate Indicator. The initial results are not good… and it looks like the indicator began falling apart shortly after the book was published. We’ll be working on making this configurable over the next few days. […]
