I wonder if someone could comment on how AI is used at big investment banks? I assume its much more than technical analysis (like this model). I imagine that NLP might be helpful for quickly ingesting a news feed and then making buy/sell decisions based on the news in less time than humans can read and react?
- AznHisoka 8y agoAs you mentioned, one way is to quickly ingest earnings announcements from press wires/company websites. As soon as the earnings report hits the wire, they want to immediately known how big a miss/beat was it, and whether they should immediately dump it or buy more. Other examples include analyzing the words/sentiments in earning calls, to see if certain words indicate a bearish or bullish signal. For example if a CEO mentions the word "headwinds", does that historically lead to a much better quarter next time? Some other companies do analysis with public/private data. For example, you can use a weather dataset to calculate the average temperature for all cities where there are restaurants owned by Cheesecake Factory in a quarter, and see if it will negatively or positively impact sales.
- this_user 8y agoI don't think you need AI for that, though. There are news feeds that are specifically designed to be machine readable. All you need to do is parse it and compare the actual numbers to the expected ones, then calculate the delta for your pricing model. All of this is pretty simple. The real challenge is being faster with this than the competition.
- AznHisoka 8y agoYou're absolutely right. None of this is AI. Wall Street is notorious for making stuff sound more impressive then it really is.
