Can individual investors outperform?

Do some individual investors consistently outperform? That is the question asked by the CXO Advisory blog in a review of a recent paper that examines the investment performance of individual investors.

Here is an abstract of the August 2007 paper in question, entitled, "Performance Persistence of Individual Investors".

This paper investigates the stock market performance persistence of individual investors. The study is based on unique data that allows us to observe month-end stock market portfolios of all individual investors over an eleven year period.

We find that a substantial number of investors exhibit economically and statistically significant performance persistence. This is robust to how we measure past performance, how often investors trade and whether investors are small or large. Unlike the evidence from mutual and pension funds, the persistence in performance we uncover is not concentrated in investors with poor prior performance. We also show that forming a portfolio that is long in stocks previously favored by top performing investors earns a substantial risk adjusted return in the future.

Slate profiles Victor Niederhoffer

Slate's recent profile of writer/speculator, Vic Niederhoffer has been getting some attention from traders and finance types in recent days. I thought we'd take a look at it here too, to offer up some possible educational value from Vic's experiences with trading and loss. Here's an excerpt from Slate's profile of Victor Niederhoffer : " I've enjoyed getting your e-mails. It sounds like you've thought a lot about being wrong. Well, the reason you contacted me, to call a spade a spade, is that I'm sort of infamous for having made a big, notorious, terrible error not once but twice in my market career. Let's talk about those errors. The first was your investment in the Thai baht, which pretty much wiped you out when the Thai stock market crashed in 1997. I made so many errors there it's pathetic. I made one of my favorite errors: "The mouse with one hole is quickly cornered." That is key. There are certain decisions you make in li

William O'Neil Interview: How to Buy Winning Stocks

Investor's B usiness Daily founder and veteran stock trader, William O'Neil share d his trading methods and insights on buying winning stocks in an in-depth IBD radio interview. Here are some highlights from William O'Neil's interview with IBD: William O'Neil's interest in the stock market began when he started working as a young adult.  "I say many times that I didn't get that much out of college. I didn't have much interest in the stock market until I graduated from college. When I got married, I had to look out into the future and get more serious. The investment world had some appeal and that's when I started studying it. I became a stock broker after I got out of the Air Force."    He moved to Los Angeles and started work in a stock broker's office with twenty other guys. When their phone leads from ads didn't pan out, O'Neil would take the leads and drive down to visit the prospective customers in person.
