Question

Your friend is thinking about buying shares of stock in a company. You have been tracking the closing prices of the stock shares for the past 90 trading days. Which type of graph for the data, histogram, Pareto or time-series, would be the best to show your friend? Why?

Answer 1

The most meaningful graph would be a standard time-series chart of closing price vs. date. It will show trends and possible technical patterns such as "breakout", "trading range" and "head and shoulders"
