Welcome!

Welcome to the Prescient Coding Challenge 2024!

The Problem Description

You have been provided with price and financial data for 100 US stocks. Your task is to generate 1-day-ahead trading signals for each stock. Additionally, you need to select the top 10 stocks each day to form a portfolio. The performance of your selected portfolio will be evaluated based on the total return index over the evaluation (test) period.

This type of trading is known as swing trades. You are only allowed long positions, i.e. you matrix of buys will only contain 1's and 0's.

You are given files

  1. README.md - this file
  2. data0.csv - 1st data file
  3. data1.csv - 2nd data file
  4. returns.csv - returns file
  5. solution.py - a skeleton structure with sample solution for the problem description

The Data

The data provided is a mix of daily, monthly, and yearly data. Where possible the data has been issued daily otherwise forward filled to match the pricing data availability.

  • The file data0.csv contains the security sector data
  • The file data1.csv contains price, historical returns, financial ratios and the 1-day-ahead price change label for each security and trading day

A brief description of the columns in the data are:

  • date - close of business day
  • security - the instrument code, in this case its the stock ticker
  • sector - the security's sector classification
  • price - closing day price in USD
  • ratio_pe - price to earnings ratio
  • ratio_pcf - price to cash flow ratio
  • ratio_de - debt to equity ratio
  • ratio_roe - return on equity
  • ratio_roa - return on assets
  • label - a 0 or 1 label, with 0 indicating a loss taking bet and 1 a positive winning bet

Ratios Reading

The Output

We are interested in the total payoff for the buys in the testing period 2024-01-01 to 2024-06-30. The high level steps are

  1. Generate buy-signals
  2. Create a buy-matrix of 1s (buys) and 0s (don't buy) with each row summing to 10 (10 buys)
  3. Generate payoff chart

Your buy-matrix will create your payoff chart using the plot_payoff function.

Hints

  • You may use a subset of features.
  • You may engineer features using the existing features.
  • You may use pure rule based, quant, or ML methods
  • You may create more than 1 model to generate buy-signals
  • ChatGPT is allowed

Grading Guide

The table below is the 1st grading guide.

Step Criteria Action
1 Submitted on 5 October 2024 before 2pm? Yes - next step, no - disqualified
2 No tampering with data sets and no additional data imports of any kind? Yes - next step, no - disqualified
3 Script runs without intervention from us? Yes - next step, no - disqualified
4 Script runs within 10 minutes? Yes - next step, no - disqualified
5 Does it produce the same solution on consecutive runs? Simulation and stochastic estimation needs to be highly stable. Yes - next step, no - disqualified
6 Does not contain look-ahead bias? Stock picking in this case will be considered look-ahead because you can see future prices. Yes - next step, no - disqualified
7 Successfully feeds into TRI function and produces desired chart? Yes - next step, no - disqualified

The 2nd grading is a combination of the classification score, TRI final level and the solution originality decided by the Prescient Investment Management Team.
