This is meant for my experimenting and educational purposes :)
In this experiment, I will attempt to analyse stock ticker symbols using sentiments garnered from the news, sentiments on Twitter, and fetch the sentiments analysed by AWS Comprehend. The app will fetch buy recommendations from Yahoo Finance as well.
This might provide a quick and basic way to display stock information at one's fingertips. [Will attempt to improve this in the near future]

Use this API at your own risk. You will be billed by the second, even when you're not using it! So take care and delete the API on AWS when not using.
