The ETF is up 8. Answers were edited for clarity and length. If you think about algorithmic trading or robo-advisers these are tools that are used by human portfolio managers to make decisions on what to invest in. Artificial intelligence is very, very different. Q: Is AI better at picking stocks and curating funds than more conventional approaches? A: We will find out. Theoretically, it should be better, because it has the ability to crunch a much larger universe of daily information and risk-weigh and apply it to a portfolio much faster and efficiently than humans can.
In addition, the computer learns from its past actions and the result of those actions and gets smarter over time. A: The more predictive information you can have and analyze, the better. Initially only a few money-managers had the technology to crunch the numbers. Now everybody does. Some quant funds, like Bridgewater, use algorithms to perform data analysis, but call on humans to select trades.
However, many quant funds, such as Two Sigma and Renaissance Technologies, are pushing automation even further, by using machine learning and artificial intelligence AI to enable the machines to pick which stocks to buy and sell.
If so, that could lead to a better understanding of how markets work, and what companies are worth. The execution of orders on the stockmarket is now dominated by algorithmic traders. Equity-derivative markets are also dominated by electronic execution according to Larry Tabb of the Tabb Group, a research firm. Much of that volume is high-frequency trading, in which stocks are flipped at speed in order to capture fleeting gains. High-frequency traders, acting as middlemen, are involved in half of the daily trading volumes.
Even excluding traders, though, and looking just at investors, rules-based investors now make the majority of trades. Three years ago quant funds became the largest source of institutional trading volume in the American stockmarket see chart 2. Machines are increasingly buying to hold, too.
A prism by which to see the progress of algorithmic investing is hedge funds. The sole exception, Man Group, a British hedge fund, bought Numeric, a quantitative equity manager based in Boston, in This figure probably understates the shift given that traditional funds, like Point72, have adopted a partly quantitative approach.
The result is that the stockmarket is now extremely efficient. The new robo-markets bring much lower costs. Passive funds charge 0. Active managers often charge 20 times as much. The lower cost of executing a trade means that new information about a company is instantly reflected in its price.
Rock-bottom fees are being passed on, too. On October 1st Charles Schwab, a leading consumer brokerage site, and TD Ameritrade, a rival, both announced that they will cut trading fees to zero. Cheaper fees have added to liquidity—which determines how much a trader can buy or sell before he moves the price of a share.
More liquidity means a lower spread between the price a trader can buy a share and the price he can sell one. But many critics argue that this is misleading, as the liquidity provided by high-frequency traders is unreliable compared with that provided by banks.
It disappears in crises, the argument goes. A recent paper published by Citadel Securities, a trading firm, refutes this view. The strategy of factors that humans devised when technology was more basic is now widely available through ETF s. Some ETF s seek out stocks with more than one factor. Each added level of complexity leaves less for human stockpickers to do.
To understand the coming developments in the market, chess offers an instructive example. It was a triumph of machine over man—up to a point. Deep Blue had been programmed using rules written by human players. It played in a human style, but better and more quickly than any human could.
Jump to , when Google unveiled AlphaZero, a computer that had been given the rules of chess and then taught itself how to play. It took four hours of training to be able to beat Stockfish, the best chess machine programmed with human tactics. Intriguingly, AlphaZero made what looked like blunders to human eyes. For example, in the middlegame it sacrificed a bishop for a strategic advantage that became clear only much later. Quant funds can be divided into two groups: those like Stockfish, which use machines to mimic human strategies; and those like AlphaZero, which create strategies themselves.
For 30 years quantitative investing started with a hypothesis, says a quant investor. Investors would test it against historical data and make a judgment as to whether it would continue to be useful. Now the order has been reversed. Humans are not out of the picture entirely. Their role is to pick and choose which data to feed into the machine. But just as AlphaZero found strategies that looked distinctly inhuman, Mr Jacobs of Lazard says AI -driven algorithmic investing often identifies factors that humans have not.
Such new factors will eventually join the current ones. But for a time they will give an advantage to those who hold them. Many are cautious. Others are outright sceptics—among them Mr Dalio.
