Data Privacy, Twitter Data, Reddit Traders, Hedge Funds, AI & Data Gaps, and Digital Maps

This week we begin with an article on data privacy and how Big Techs have been exploiting user data — by selling user-profiles to advertisers and using images to train biased facial recognition systems — and further causing data breaches and hacks. Next is an analysis of Twitter’s announcement to make data available for free to third-party academic researchers interested in social media discourse about online misinformation, election interference, hate speech, and other platform trends. Following this is an article on how much damage a Reddit army of retail traders caused to the US stock market, by chasing a handful of the most-shorted hedge funds and causing a surge in stocks like GameStop and AMC Entertainment Holdings. The following piece is on hedge funds, and how they are seeking real-time data about discussions on Reddit and Twitter — to identify the most talked-about companies, determine trade sentiments, and mitigate investment risks. Next is an analysis of AI’s role in collecting, analysing, and reporting economic data in India. To end, we have a piece on Digital Maps, interactive data hubs powered by a geographic information system (GIS), and how they help businesses make decisions related to market and customer analysis, operational efficiency, supply chain digitisation, and more.

A Reddit army descends on hedge funds chained by risk models

A hellish week for hedge funds will be remembered for how much damage Reddit traders caused by chasing a handful of the most-shorted names in the $43 trillion U.S. stock market. But just why were the institutional pros forced to downsize their market exposures at the fastest pace since pandemic-spurred March rout? One reason is that their risk models told them to. As a flood of retail money sent stocks like GameStop Corp. and AMC Entertainment Holdings Inc. surging, the trading signals that guide how the smart money invest flashed red.

Hedge funds rush to get to grips with retail message boards

Hedge funds accustomed to poring through arcane corners of earnings reports in search of companies to bet against are turning their sights on foul-mouthed online message boards in an effort to stay ahead of day traders who have started beating them at their own game.
