This project presents a comprehensive analysis of a year's worth of synthetically generated financial data, focusing on the performance of major stock market companies and their associated indexes. By leveraging object-oriented programming principles and advanced data analysis techniques, this project provides valuable insights for informed decision-making in the financial sector.
- Analyze performance metrics of three major companies: DJ, NASDAQ, and SNP
- Examine the categorization of companies as LargeCap or Non-LargeCap
- Investigate nine important financial indexes and their behavior patterns
- Create compelling visualizations to extract meaningful insights for strategic planning
- DJ (Dow Jones) - Non-LargeCap
- NASDAQ - Non-LargeCap
- SNP (S&P) - LargeCap
| Company | Indexes | Market Type |
|---|---|---|
| DJ | D30, DSI, IA | Non-LargeCap |
| SNP | 400, 500, 300 | LargeCap |
| NASDAQ | SOX, NDX, NQGI | Non-LargeCap |
- Ratings: Measure of company performance
- Prices: Financial value of each index
- Fluctuation Rate: Volatility indicator for each index
The project employs a sophisticated object-oriented approach to model financial data:
# Base Index class with core attributes
class Index:
def __init__(self, date, index_name, company, type, rating, price, fluct_rate):
self.date = date
self.index_name = index_name
self.company = company
self.type = type
self.rating = rating
self.price = price
self.fluct_rate = fluct_rate
self.unique_id = id(self)Inheritance Hierarchy:
Index(Base Class)LargeCapIndex(Inherits from Index)SNP(Inherits from LargeCapIndex)
NonLargeCapIndex(Inherits from Index)DJ(Inherits from NonLargeCapIndex)NASDAQ(Inherits from NonLargeCapIndex)
| Library | Purpose | Key Usage |
|---|---|---|
| pandas | Data manipulation and analysis | DataFrame operations, groupby, data cleaning |
| numpy | Numerical computing | Statistical calculations, array operations |
| matplotlib.pyplot | Static visualizations | Pie charts, histograms, bar charts, line plots |
| seaborn | Statistical data visualization | Box plots, scatter plots, enhanced styling |
| pickle | Binary data serialization | Loading data from .dat files |
| csv | CSV file operations | Data export and processing |
# Load and examine the dataset
stock_data = pd.read_csv("data.csv")
stock_data.info() # Data types and structure
stock_data.isna().sum() # Missing value analysis- Missing Value Imputation:
- Date columns filled with mode values
- Rating columns filled with mean values
- Price and fluctuation rate values imputed using group-wise means
- Feature Engineering:
- Date parsing and extraction of month, year, quarter components
- Categorical data standardization
# Group-wise imputation for missing values
stock_data['price'] = stock_data.groupby('index_name')['price'].transform(
lambda x: x.fillna(int(round(x.mean())))
)Distribution of Market Type:
- Key Finding: Dominance of mid-sized and smaller companies (Non-LargeCap)
- Insight: Limited number of companies operate with substantial capital
SNP Index Distribution:
- Key Finding: Balanced distribution across SNP's large-cap indexes (300, 400, 500)
- Insight: Equitable market representation within the LargeCap segment
Rating Distribution by Company:
- Key Finding: Consistent median rating of 3.0 across all companies
- Insight: Uniform data distribution with no outliers, suggesting stable performance metrics
Quarterly Fluctuation Rate Trends:
- Key Finding: Average fluctuation rate consistently around 15-16 across all indexes
- Notable Exception: NDX and SOX showed heightened volatility in Q1 (>20% fluctuation)
- Insight: NQGI demonstrated the most stable performance throughout the year
Fluctuation Rate Distributions:
- Key Finding: Bell-shaped curves centered around 15 for all companies
- Notable Pattern: NASDAQ exhibits spike between 15-17.5, indicating higher volatility
- Insight: Supports heatmap findings regarding NASDAQ's increased fluctuation
Average Price vs. Average Fluctuation Rate:
- Key Finding: Non-linear relationship between price and fluctuation rate
- Critical Insight: Tight cluster around mean price of 250 and fluctuation rate of 15
- Implication: Strong correlation suggests stability and predictable trading range
DJ Index Performance by Quarter:
- D30 & IA: Declining trend over the financial year
- DSI: Consistent performance with Q2 dip
- Analysis: Price decline influenced by internal (management changes) and external factors (global events)
Monthly Price Trends:
- NASDAQ: Sudden fluctuations with rapid recovery
- General Trend: Overall decreasing trend but stabilization around mean of 250
- Insight: All companies eventually converge to stable patterns
- 67% of the market consists of mid-sized and smaller companies
- SNP large-cap indexes show balanced distribution, indicating market maturity
- DJ company indexes demonstrate the highest stability among the three
- Q1 Volatility: NDX and SOX experience heightened volatility early in the year
- Stabilization Trend: Most indexes stabilize around 15-16% fluctuation rate
- NQGI Performance: Consistently low volatility makes it attractive for risk-averse investors
- Stability Indicator: Tight clustering around price 250 and fluctuation 15 suggests strong market correlation
- Risk Assessment: DJ indexes offer the most stable investment option
- Timing Strategy: Q1 volatility in tech indexes (NDX, SOX) may present trading opportunities
