CEO changes usually have articles written about them. So why not use the CEO change dataset in combination with a news sentiment dataset to determine whether a CEO change is good or bad, and invest accordingly?
I've attached a notebook where I find matches between the EventVestor CEO Changes dataset and the Accern Alphaone News Sentiment dataset, and do some basic analysis to see if there's any rank correlation between the combined data and price movements. The result is a weak negative rank correlation between news sentiment shortly following a CEO change and relative price movement. This might be a good enough signal to contribute to a long-short trading strategy.
Pipeline and the tools available in Research make it easy to try to find signals of your own to use in a trading strategy. Try cloning this notebook to test out similar techniques on some of the other datasets we have available.
