Hi
Something a little bit more complicated to read and quit interesting.
The first article is about : Just How Much Do Individual Investors Lose by Trading?
http://rfs.oxfordjournals.org/cgi/content/abstract/22/2/609
A brief conclusion :
Individual investor trading results in systematic and economically large losses. Using a complete trading history of all investors in Taiwan, we document that the aggregate portfolio of individuals suffers an annual performance penalty of 3.8 percentage points. Individual investor losses are equivalent to 2.2% of Taiwan's gross domestic product or 2.8% of the total personal income. **Virtually all individual trading losses can be traced to their aggressive orders.** In contrast, institutions enjoy an annual performance boost of 1.5 percentage points, and both the aggressive and passive trades of institutions are profitable. Foreign institutions garner nearly half of institutional profits.
After reading the whole PDF : ** This sentence is for me as retail trader the most interesting conclusion in the whole article. It shows clearly, that individuals more tend to speculate and hope of the quick big run than the professional, institutional traders do. And here is one of the biggest reasons clearly explained and explored, why so many retail trader loose there money in trading.
Here is an other PDF which gives informations about : Return autocorrelation and institutional investors. You may not want to read the above PDF, after you have the conclusion, so enjoy that one. It has a lot of interesting points to think over.
