Problem
CoStar Group (NASDAQ:CSGP) is a stock listed on NASDAQ exchange.
You will consider the time-period and daily share price of the company for the period 1st of February 2021 until 10th of August 2022.
Provide a bar or candlestick chart (or multiple charts) of the daily share price for the time period above. Identify at least three days, where news stories, events or issues related to the company have majorly impacted the share price. Evaluate and discuss the magnitude and direction of the price changes (opening to close) of the instances you have identified. Your answer should consider why the news/event/story impacted the share price in the manner that it did, as well as other considerations (e.g., theoretical, market, behavioural) besides the identified news articles that you believe would have impacted the share price.
Next, use the chart created above and a technical analysis tool from learning module 4 to predict future stock price movements. What does your analysis indicate if you were an existing investor? (would you buy, sell or hold?). What does the usage of technical analysis mean for the theory of market efficiency?
