Analyzing the Price of Macintosh Computers Over Time using Scrapy

Posted on Dec 12, 2019

Apple Inc. (AAPL), founded in 1976, became the first U.S. corporation to surpass $1 trillion in market capitalization last year as its iPhone fueled spectacular growth in sales, profits and its share price. Since then, the company aggressively moves to transform itself from a seller mainly of tech hardware devices into one of the world’s leading providers of digital services. To do that, Apple must sharply boost the sales it gets from software and services. As a result, the sale of Macintosh Computers now makes up a mere 16% of its total revenue.

To extract Data, I used Python & Scrapy. Scrapy is a wonderful tool within Python, it is a perfect fit for Data Scientists who want to answer a question where the current data set does not currently exist.  For my implementation of the library, I decided to look at Macintosh computers, their prices over time & how they related to the interest rates & the price of Apple’s stock price.

To get the correct information for my data set I looked for websites that contain large amounts of data about historical pricing of Macintosh machines, as has no pricing outside of their current product lineup.  I eventually landed with, as it stores large amounts of data, matched my query & had a wide range of different machines from 1991 to present.

Here we see Price over time that is not adjusted for Inflation
Price over Time ~ Inflation Adjusted
