Wrong sentiment returned
I tried the following two message and got negative sentiment.
"The market has been going up lately."
"The global economy is still growing."
They should clearly be positive.

We have recently released a new version of sentiment analysis.
You can read more about the new v3.0-preview API in the following link - https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/how-tos/text-analytics-how-to-sentiment-analysis#sentiment-analysis-v3-public-preview
The new API will consider most of these kind of vertical specific sentences as factual and thus Neutral.
If you are interested in domain specific flavors of sentiment analysis feel free to open a new suggestion.
