    Study Notes

    Exploratory Data Analysis (EDA)

    • EDA in finance is like getting to know your financial data, to understand patterns and characteristics.
    • EDA is the first step to make decisions about further analysis and find insights.

    Visualizing the Data

    • EDA uses graphs and charts like line charts, histograms, and scatter plots to see trends and changes over time.
    • For example, you can plot stock prices over 10 years to see patterns like uptrends, downtrends, and periods of volatility.
    • Boxplots and histograms help visualize how data is spread out, for example, how often stock prices are high or low, and if there are any unusual jumps.

    Descriptive Statistics

    • These are basic calculations that help understand the main features of data:
      • Mean: The average value
      • Median: The middle value, helpful when data has outliers
      • Standard Deviation: Measures how spread out the data is, in finance it can help measure risk or volatility
      • Correlation: Shows how different financial variables move together, for example, observing whether two stocks rise or fall at the same time.

    Handling Missing Data

    • Sometimes, there is missing information in the dataset.
    • EDA helps to identify these gaps and decide how to address them: remove, replace, or fill in with an estimate.

    Identifying Outliers

    • Outliers are values significantly different from the rest, like a stock price suddenly jumping by 50% in a day.
    • EDA helps to spot these, which can affect analysis and predictions.

    Factors Affecting Stock Prices

    • Various factors can influence stock prices, such as:
      • Interest rates
      • Inflation
      • Company earnings
