Today, there exists an enormous amount of data about every company— data which potentially can influence stock prices and other investment opportunities. As individuals, we may struggle to keep up with the torrent of information from hundreds or even thousands of sources. But new data-analysis tools can help find signals in the noise.
For example, tools which spot surging web traffic can help pinpoint sales trends faster than traditional methods. Satellite images can be studied to detect the movement of shadows across the floating lids of oil storage tanks – the shadows can reveal refineries’ supply and production capacity on a real-time basis, potentially ahead of official statistics.
