  • 1. Hadoop Project Stock Analyzer (Mapreduce and Hive Implementation) Presented by Punit Kishore(A13011) Debayan Datta(A13006) Sunil Kumar P(A13020) Maruthi Nataraj K(A13009) Ashish Ranjan(A13004) Praxis Business School
  • 2. AGENDA  Understanding of the problem  Technical Architecture  Basic Structure  Pseudo Code  Final Result  Business Implications Electronics Template
  • 3. UNDERSTANDING OF THE PROBLEM  Objective : To find the adjusted closing price for each day that a stock not reported a dividend.  Data Sources :  NYSE daily prices dataset with the below schema exchange stock_symbol date stock_price _open stock_ price_high stock_price _low stock_price _close stock_volume stock_pric e_adj_close  NYSE dividends dataset with the below schema exchange stock_symbol date dividends  Isolation of dividend data from total data will give better picture of the company because sometimes firms avoid cutting dividends even when earnings drop.

  • 22. BUSINESS IMPLICATIONS  The daily close stock prices are adjusted for dividend distributions/stock splits because they are a part of total return and affect the historical volatility estimates .  The primary use for the adjusted closing price is as a means to develop an accurate track record of a stock's performance. The comparison of a stock's historical adjusted closing price to its current price shows the true rate of return.  Graphing the volatility history of the target firm simultaneously with that of its competitors and Market Index can provide unique insights into risk and comparative advantages(frequency distribution of returns can also be used).  Historic stock price volatility might have implications to business valuators.
