Super Simple Stocks

Super simple stocks is an application to manage trades on a set of stocks and it's a technical test as part of the hiring process for a very important company.

1. Assignment Description

Requirements

  1. Provide working source code that will:

    a. For a given stock:

    i.    Calculate the dividend yield.
ii.   Calculate the P/E Ratio.
iii.  Record a trade, with timestamp, quantity of shares, buy or sell indicator and price.
iv.   Calculate Stock Price based on trades recorded in past 15 minutes.

    b. Calculate the GBCE All Share Index using the geometric mean of prices for all stocks

Constraints & Notes

  1. Written in one of these languages:

    • Java, C#, C++, Python.

  2. No database or GUI is required, all data need only be held in memory.

  3. Formulas and data provided are simplified representations for the purpose of this exercise.

Global Beverage Corporation Exchange
Stock Symbol Type Last Dividend Fixed Dividend Par Value
TEA Common 0 100
POP Common 8 100
ALE Common 23 60
GIN Preferred 8 2% 100
JOE Common 13 250

2. Solution

A solution for the assignment is designed to provide a service which has operations to calculate the dividend yield, P/E Ratio,Stock Price and record trades for a given stock. Besides, the service provides an operation to calculate the GBCE All Share Index for all stocks supported by the Super Simple Stocks application. Providing this service, all the requirements of the assignment are met.

Responding to one of the constraints, the implementation of the solution is written in Python language. I also believe that the application benefits
of thread-safe implementation. Since such a requirement has not been stated explicitly in assignment I have not considered in my design.

Unit Test

I follow a Test Driven Approach to test the code of the technical test. A comprehensive unittest conducted. I believe that the application benefits an extensive functional test. However, due to time constraint I was not able to implement the functional testing. I can complete this task if the assignment deadline extended.

Try Yourself

The code for the technical test was built as a PyCharm project. To compile the code, download the folder super_simple_stock and import the project in PyCharm.
