Algorithmic Investors on Wallstreet 249
eldavojohn writes "Recently, setting up prediction markets that people play was the big thing to guess the future. But is there a chance that computers will replace investors? From the article: 'Quantitative investment managers use a model to identify sets of characteristics for their investments. Computing power is now relatively cheap. Obviously, computing power can access data almost instantaneously and simultaneously. Asset classes and financial instruments within those asset classes can then be screened and investments are selected. They reflect the manager's views.'"

Why would it be "irresponsible"?
And no, it's not illegal, but there are some exchange rules on it - depends on the exchange. See here: Program Trading [answers.com]

Warren Buffet has outperformed the market over many years. http://en.wikipedia.org/wiki/Warren_Buffett [wikipedia.org]
Buffet understands the economy and invests accordingly. The computer programs only understand the market. In other words they can't really respond faster than the rest of the market. Buffet can be years ahead of the market.

As for the question of "Why?", the answer is on the page you linked. Black Tuesday, for example.

Until you can look at the numbers of a company and know everything about that company with certainty (meaning that a human _could_ do it if they had an infinite amount of time), or until we have computers that are great at telling when people (enron) are bluffing, I'll stick with investmant companies that rely predominantly on humans.

If that happens, and if all the investitors has access to such software, my bet is that the whole point of investing on market will flop. Since everybody will always "win", nobody will actually make a huge profit, the money will enventually be equally distributed among all investitors.
The sad thing about capitalism is that there's always a fixed amount of money on the market, so to win somebody else has to loose. If we make a super AI, that always wins... nobody will, because to win someone has to loose.
In the end this could mean a good thing, and we can turn our attention from pure profit to things that really matters.

When everyone is crunching numbers on their head, the computing might give an advantage. If everyone is computing with compters, the advantage goes to the one with better algorithm. And the better "algorithm" might actually turn out to be thinking and looking at the global picture instead of madly computing.
When huge trades are decided by these algorithms it is almost like a huge herd of milling cattle. When the stampede, just get out of the way. But if someone could trigger a stampede and send it over the cliff, there will be rich pickings later. And in free markets, if there is a way for someone to make money, someone will.
I think algorithmic investing is the new name for the old "programmed trades" and it might actually make the thinking and studying fundamentals investors richer.
The code is
if( InputDataIsGood() && AlgorithmIsGood() && AlgorithmIsBetterThanOthers()){
Output(profit);
}else{
Output(loss);
}

I also know of a company nearby doing exactly that and doing well and have an acquaintance who retired at the age 35 or so after running his companies dept. who found (using algorithms) and exploited these patterns that don't exist.

But the real growth of the economy is all based on debt, the government decides how much to lend out and that decides how big companies get and how much money there is to pay workers and stuff.
Of course, if you get too much money out there relative to other countries (like now, where the government has been printing $500B per year of new money in the form of debt), your currency falls and your money is worth less and less. You can only push so far before people begin to lose confidence. Having a good leader can really help out the confidence, both in and out of the country. But the economy is showing that it could take the huge infusion of money pretty well and we're sending it to China and they're still taking it so what do we care?
Now, what's going to happen when we move to one world currency? Well, it's going to be a long process and there's going to be a big war and eventually we'll all settle down and we can all move a bit slower. But as long as there are more people than there is available water, food, energy, etc. it will not be possible. I think we will probably hit that population number soon. I like to follow the progress of the "Euro" because that was a major major change for the world that we haven't even felt yet. In the West we have most of S. America tied to the dollar now. Since Europe is now the biggest economy in the world, once they get the kinks straightened out, free up trade between the member states and drop tax rates, they(you) are going to be a force to reckon with.
The only country with anything to fear right now is Russia; they have a huge land mass with huge resources and on the outside you have overcrowded China and Japan in the East, and Europe on the West. But I like the Russians, I think they are some of the most brilliant people. I think they will be our friends.
