AI will now watch for fraudsters on the world's largest stock exchange
The Nasdaq stock market is an attractive target for fraudsters. As the world's largest stock exchange by volume, it must be constantly monitored for attempts to illicitly beat the system. These can include manipulations to inflate a stock's closing price; churning (rapidly buying and selling stocks) to give the false impression of a lot of activity; and spoofing (placing a large buy or sell order with no intention of actually executing) to create artificially high demand.
That monitoring is now being aided by artificial intelligence, Nasdaq, the stock market's parent company, announced today. A new deep-learning system is working in tandem with human analysts to keep watch over roughly 17.5 million trades per day.
The system augments an existing software surveillance system that uses statistics and rules to flag any signs of market abuse. In the US equity market, for example, the old system issued around 1,000 alerts per day for human analysts to investigate, says Martina Rejsjo, the head of market surveillance for Nasdaq's North America equities. Only a fraction of these cases would subsequently be confirmed as fraud and result in heavy fines.
The new system should have a number of advantages. First, Nasdaq claims it will be more accurate at identifying patterns of abuse, reducing the burden on human analysts. Second, it will be better at detecting more complex patterns of abuse, particularly spoofing, which Nasdaq believes will become increasingly common.

There are probably 1000 alerts per day just for Goldman Sachs.

They have some complex algorithm that improves its accuracy with input from human analysts? This is what “AI” is?

Right...how can you prevent fraud in a system based on fraud?

Just follow the activities of JP Morgan, Goldman Sachs, and Bank of America, and you'll have the 3 biggest sources of fraud on Wall Street.
But I'm sure what they're after is the small-timers.

Not sure I would call it fraud. I would call it more 'doing the needful'.
They hire *very* junior devs then have them handling trillions of dollars. Mistakes are made. Lots of them.
Fraud would take someone sitting down and thinking about it. You do not get that off of stackoverflow.

If they put in a one day delay between putting in the request to buy stocks and actually doing it, it would solve a lot of fraud problems -- more than just mentioned in the summary. In fact, slowing down the whole system would put a lot of sanity back in the stock system. But sanity and reason are no longer a goals of the stock market.

What about entities that buy call options on a relatively illiquid stock and then have someone else later buy that stock during non-trading hours when they are least liquid to inflate the price. The person/entity buying the stock ultimately takes an equity loss but the person that bought the call option makes money on the price increase and they give some of that money to the person that inflated the price.
