this, in conjunction w/other stuff, could be really useful in timing the medium and long term trend. imho.
Absolutely. Just looking at those data is not enough. But I am not sure their effect on the long term though. I mean longer than one year. I would doubt they can see that long...Just my 2 cents.
You can send email to the webmaster, it used to be 50 days, but then I guess he changed his mind to only show 10 days. Don't know why.
You may want to check FLO, http://www.secform4.com/insider/hotbuys.php The report of a director purchase just came in. Don't just buy it, do your own DD first. I am doing my own DD now. I would not be paying too much attention on PPHM, which also is having an insider buy. But that guy own 1.8 million shares of PPHM, and he bought 50,000 shares, a suspect of pump & dump. Just my 2c.
