I feel like I've found a bug but please let me know if I'm doing something incorrectly to see these issues. I noticed that for more than a few stocks, their closing prices are mysteriously missing for large amounts of time using Pipeline in the Research environment. One such stock I found was GM. Using the Q1500US universe, I only observe a few months in 2016 where GM actually has data. Is this a bug? It's possible for a stock to be in and out of the Q1500US I realize, but a stock as highly traded as GM seems unlikely. I also compared it to Pipeline data using the StaticAssets for GM and I got all stock prices as normal. Also, get_pricing() within Research is functioning correctly. Please see the attached notebook, it's really messing with some of the research I'm currently doing. If there is something obviously wrong with my code here please tell me! Thanks in advance.
