Project 1

Overview

This group is producing a software called Personal Stock Portfolio tracking System (PSPTS). This software will access a personal stock portfolio on a day-to-day basis. Their clients are only a small investor. The PSPTS will save their clients’ time to search through the paper for their particular stock(s) or their wait for the quarterly dividend report. Their proposed system is allows small investors to have a more convenient method to manage their stock portfolio from home base on day-to-day basis.

Questions and Comments

  1. Will the PSPTS really remove the brokers because your target clients are only small investor?
  2. Will the software really help the small investors? Here is the condition, what if the stock(s) drop suddenly during the day and the users of PSPTS do not know that incident because the stock market has not closed yet. In this condition, the PSPTS will show previous closing value but not the real-time value.
  3. I think this software will not the users very much because the value of the stock(s) will be shown is exactly the same as shown in newspapers. If the drop of the stock(s) is extreme, the PSPTS will cause the users to face bankruptcy. To me, I think it is better to have a broker to watch the stock rather than check my own portfolio base on day-to-day basis unless this is a real-time market listing software. My reason is "tomorrow is unpredictable."
  4. Do you think scanner is necessary? Why don't you ask the users to input their invested stock(s) themselves? My reason is that the PSPTS only needs four data for each stock. I don't think many users want to spend more so that they can run the PSPTS software for their investment.
