I have read somewhere that the chart contains all the information to date on any given stock (I am sure many people wouldn't agree but some hardcore tech anals have mentioned it before). But is there any way anywhere to filter for variables that really move stocks? I was thinking of a news-driven filter...one that collected (perhaps through rss feeds or something) company news from a collection of web sites and filtered that into a summary of what stocks are making news and why.

My initial thought was a points-based system that added for positive earnings and good announcements and such while subtracting for negative events and the like (sort of like counting cards for you blackjack players). A morning look at the filter could find BIDU with a rating of 6 (positive news - negative news) while ZUMZ might have -4 (a potential short). Coupled with careful tech anal I would think a filter of this nature could be very powerful.

Um...so like, what do yall, like, think, dudes?

I've been thinking the same thing. I have a feeling that although it's definitely something that can be done, it would be an extensive undertaking.

I use another website that rates stocks using earnings criteria so I know it can be done, but including it in a stockfetcher filter might too much to ask.

What say you, stockfetcher?

A quick thought.

How would a machine know what "positive" or negative" news is?

Key words. Or for that matter, if some financial site wanted to invest in the idea of a news-based filter they could hire a few people to sort through news coming in and assign it points. A hassle, yes, but if it had true merit people would subscribe to have access. That would pay for itself, no?

Hey that is pretty cool. You seem pretty far from a curmudgeon, Mr. Curmudgeon.

Holy smokes...today I noticed at the bottom left of the Yahoo! Finance page there was a little box labled "Market Movers: Newsworthy", and it listed stocks with big moves and is "Determined based on increased frequency of appearance in news"

Wow...that is *almost* what I was looking for when I started this thread! Close enough to be impressed!

On Google Finance they have letter tags on the chart to match news events on the right column. I dont get why GOOG dont do more with their Finance website, doesnt look like it even supports candle charts..

TRADING RULE 43.

It is better to be more interested in the market's reaction to new information that in the piece of news itself.
