Stock Badger Android App

Download the Stock Badger App at the Google Play Store.

Stock Badger uses Machine Learning and Natural Language Processing Algorithms to automate the evaluation of market sentiment.

Why is market sentiment and current news valuable? The article “Financial News Predicts Stock Market Volatility Better Than Close Price” in The Journal of Finance and Data Science (June 2018) by authors Adam Atkins, Mahesan Niranjan, Enrico Gerding explains why. In the article, they say “empirical results show that the average directional prediction accuracy for volatility, on arrival of new information, is 56%, while that of the asset close price is no better than random at 49%.”

Stock Badger processes and analyzes 100 current energy sector Tweets to determine if the sentiment is Bullish, Neutral or Bearish. The breakdown of the sentiment scores are displayed for easy reference.

In addition, Tweets are able to be viewed and read inside the app. It keeps users current on energy market news and economic conditions.

Stock Badger provides market information on 50 top energy companies. A sentiment meter shows Bullish, Neutral or Bearish based on the 52-Week Range.

An explanation of the stock price information contained in Stock Badger is given below using Exxon Mobil (XOM) as an example.

 Exxon Mobil Corporation (XOM)

52-Week Range: The measure for a company’s stock price relative to the low and high over the previous year. For the calculation, the low of the 52-Week Range is -1, middle is 0, and high is +1. For example, a stock with a 52-Week Range value at +0.85 is close to its 52-Week High.

 52-Week Return: Calculates the one-year return of owning the stock. A comparison of XOM stock’s percent return relative to the S&P 500 is shown in the plot. The starting point is 52 weeks or 1 year in the past.

Historical Volatility: A measurement of how much a stock moved up or down in the past. The annualized standard deviation of stock price daily returns.

Beta vs S&P 500: An metric that assesses the risk and associated volatility of a stock in relation to the S&P 500. How much does the market movement affect the stock? If the Beta equals 1, then the asset’s volatility matches that of the S&P 500. If the Beta is greater than 1, then the stock is deemed to be more volatile than the market and if it’s less than 1 then the stock is deemed to be safer.

Correlation: How much other stuff is contributing to the stock’s return? A high correlation means stock price movements can be attributed directly to market movements. A low correlation means the stock has its own idiosyncratic variables that affect price.

Market Capitalization: The total value of the company based on share price. Cost per Share x Number of Shares.
