the market is so volitile that if you play by the charts and stats, you have to screen dozens to hundreds of companies- and for each of these, many many variables like 52 wk high, low, market cap, sector, recent performance, PE, etc.
you could use a face to describe all these things very quickly (not
detailed, but a fast way to get an overview). the PE could be the slope of the smile (frown). the sector could be the hair style. etc.
obviously, programs exist to draw graphs in realtime, so you would be able to automate the face. in fact, speaking of realtime, you could animate the faces!
further, these faces could be plotted in order to identify "strangers" or promising types. i first had the idea of using some made-up cartoon character. then i discovered some social scientist (chernoff) already developed the idea of using faces. i think it's time to use this great idea for stocks. i think it would be particulalrly useful with clearstation.com.
of course the real charts are availalbe. click on the nose or whatever. this is just a more effective presentation.
