"100 portfolio managers buy and sell 100 million shares a day"
Luck should have been mentioned but the sheer volume of trades and absurd average over 18 years makes it seem like they DO have some special sauce... and a lot of it.

In general, most trades are a wash, not a huge up or down swing. It's the big events, like betting against the dotcom crash, betting against enron, etc, which make or break this size fund.
Those are the 9 or 10 events I'm talking about. These people are probably rarely betting on something more than 1:10 odds. But for those huge cases, they were probably getting 1:100 or 1:1000. Those are the ones it is so important to be on the right side of, and dampen quite a bit of suboptimal whatever in the meanwhile.
He quite specifically bet against the housing and dotcom boom as mentioned in the article, therefore shows to be betting most importantly on those 1:1000 events.

since when does trading volume suggests special sauce? you can buy and sell 100 million shares a day and only trade 20 stocks.
I didn't suggest volume alone suggested special sauce, " sheer volume of trades and absurd average over 18 years makes".
I was more trying to get the point across that they weren't rolling one die for 18 years but rolling it thousands of times.
All this talk about special sauce is making me hungry...

SAC Capital is not #1024. They literally have strong control over the markets. Their process, systems, and relationships allow them to, for example, buy all of the offered stock from multiple investment banks at once, constraining the supply.
It's really a failure of regulation.

That is certainly enlightening to the discussion: They're not lucky, they just hold all the cards.
The article is basically a puff piece. How about a more critical view of SAC and hedge funds in general: http://www.fool.com/community/pod/2005/050401.htm
I used to read these stories and salivate at the thought of these superhuman investors. Now I read just see them as gamblers making big bets with someone else's money.
Lots of fluff in the article.
The only real explanatory investment comments I saw were about him timing his exit of both the tech bubble and the housing/credit bubble right near the peak, riding both to the top and then betting against both to the bottom. If you know an investor who successfully did both of those things without making any huge mistakes along the way, you know an investor who's averaged gaudy returns.
What it doesn't tell us is how he "knew" those bubbles were about to burst. How much of a role did luck have?

A bit of a fluffy piece but interesting to think that 30% for 18 years yields $112 after an initial investment of $1 (1.3^18). Or $5,000 18 years ago is worth a half a million today.
Insider trading?
Given enough series of die rolls by enough different rollers, there is inevitably going to be some with long strings of success.
It only takes looking at 1024 cases before you find someone who bet correctly on 10 binary decisions.
There are assuredly more than 1024 funds.
He might have some special sauce, or may have done some smart things, but it is just as possible he's just #1024
