I think this is an interesting topic.
It's good that you're sentiment analysis is based on qualitative information from tweets as well as quantitative data from Yahoo Finance

Are you going to get your word list of sentiments from somewhere? How so?
I don't understand the use of investment back-testing. Are you saying you're looking at the sentiments of each stock in a portfolio, then predicting the financial returns? If so, then I think this is really interesting because you're analyzing both individual stocks as well as portfolios where combined effects of multiple stocks together could yield expected/unexpected results.
