I'm trying out an insider trading service, basically the idea is to follow insiders because they know something we don't. Today they have reported a CEO purchase of 10K shares at HGSI:

looks interesting, however it looks like the COO just sold 50K shares just a few days ago... seems like a bit of a contradiction...

I actually have (I'm new but I've done some homework) . Here is a book by the chair of the finance department at the University of Michigan business school, which studies insider trades between 1975 and 1995. During the 20 years insiders were able significantly beat the market:Alternatively, you might like to conduct a serious research product on the relationship between insider trading and stock price movements to determine the value of this information.

For example, he claims that top executives in small firms (<$25M) buying shares in their own companies had 12.3% net return (i.e., 12.3% over the average market return) over the next 12 months. I think this sounds very impressive.
I agree, the biggest challange that I find it to weed out all the noise information, but I do believe there are some interesting trades to be followed.I may be wrong (which is often the case), as I am just speculating here and have done no tests myself, but my guess is that this information is of negative value when you include the cost of the information, the time spent reviewing it, and the opportunity cost of both.
Another aspect of it that I'm noticing is the "news" factor. For example, take HGSI, which has started the discussion. The report came out yesterday, the stock is up over 5% today... and, of course, I didn't get in! ... Well I still don't like the fact that the CEO is new to the company and that the COO had sold 5 times the amount just two days before the purchase.
Well, if took for them 20 years to find such thing out why they're not as rich as George Soros, Paul Tudor Jones or othe rgreat traders and investors? just think of investing as a job, you'll find a niche someday, you just dont know exactly when, its just like any other job...demosthenes wrote:I actually have (I'm new but I've done some homework) .
