Shares of C3.ai (NYSE: AI) were pulling back again this week as the software-as-a-service company for artificial intelligence continues to fall out of favor. The primary culprit for the sell-off was an analyst downgrade, but the stock also missed out on big gains in the Nasdaq index after tech giants like Microsoft and Meta Platforms turned in strong numbers. According to data from S&P Global Market Intelligence, C3 AI was down 12.3% for the week through Thursday's close.
