"Authorities are exploring potential holes in the system, including new algorithms referred to as “news aggregation” that search the internet, news sites and social media for selected keywords, and fire off orders in milliseconds. The trades are so quick, often before the information is widely disseminated, that authorities are debating whether they violate insider trading rules, the people familiar with the matter said."
It makes me wondering if above technology-driven trading trick was using Big Data technology. If some people or companies are able to use Big Data to generate benefits for other people or customers, there must be some guys who can take advantage of Big Data to make money for themselves.
Why did Big Data make a bad thing so easily?
- Big Data especially people's social network information from Internet are easily be accessed and consumed.
- There are so many Open Source technologies which can help on processing the Big Data.
- The cloud computing make Big Data crunching faster.
- The fast-growing IT technology including hardware and software drive the Big Data processing cost lower.
There is no way to stop people to access the Big Data just like no way to stop the data getting big. Like fighting computer virus, people has to keep their anti-virus software updated. So for the above computer trading case, FBI and SEC have to get them equipped with Big Data technology to fight those guys who also know the Big Data.
