Predicting Stock Prices of Cisco【CSCO】 : A Data Analysis and Machine Learning Approach Using Python

Predicting Stock Prices of Cisco【CSCO】: A Data Analysis and Machine Learning Approach Using Python Introduction

In this article, we will discuss how to predict the stock prices of Cisco【CSCO】 using Python.Predicting stock prices is essential for investors, and we will use data analysis and machine learning techniques to make these predictions. Data Collection and Preprocessing

First, we need to collect historical stock price data for Cisco【CSCO】 and preprocess it as needed. Stock price data can be obtained from financial websites such as Yahoo Finance or Google Finance. Below is an example of how to retrieve Cisco【CSCO】's historical stock price data using the yfinance library in Python:

import pandas as pd import yfinance as yf

Downloading stock price data

stock_data ="CSCO", start="2020-01-01", end="2022-01-01")

Checking the data


This code snippet uses the yfinance library to download historical stock price data for Cisco【CSCO】 and stores it as a pandas DataFrame. We then check the first few rows of the data to ensure that it has been downloaded successfully. Feature Selection

Next, we need to select the features that will be used in our prediction model. Several factors can influence stock prices, but some common features include:

  • Historical price movements
  • News and event information
  • Technical indicators (moving averages, RSI, etc.)

These features need to be collected and appropriately preprocessed. For example, historical price movements can be represented using indicators such as moving averages or Bollinger Bands. Model Building and Training

Once we have selected our features, we can proceed to build and train our prediction model. In this example, we will use the Random Forest algorithm, which is an ensemble learning method that combines multiple decision trees to produce highly accurate predictions.

from sklearn.ensemble import RandomForestRegressor from sklearn.model_selection import train_test_split from sklearn.metrics import mean_squared_error

Preparing features and target variable

X = stock_data'Open', 'High', 'Low', 'Volume' # Opening price, High, Low, Volume y = stock_data['Close'] # Closing price

Splitting the data into training and testing sets

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

Building and training the Random Forest model

rf_model = RandomForestRegressor(n_estimators=100, random_state=42), y_train)

Making predictions on the test data

y_pred = rf_model.predict(X_test)

Evaluating the model

mse = mean_squared_error(y_test, y_pred) print("Mean Squared Error:", mse)

This code snippet uses the scikit-learn library to build and train a Random Forest regression model. We split the data into training and testing sets, train the model using the training data, and then evaluate its performance using the test data. Visualization and Evaluation of Results

Finally, we visualize the model's predictions and compare them with the actual stock prices. This allows us to evaluate the model's performance and make any necessary adjustments.

In conclusion, we have demonstrated how to predict the stock prices of Cisco【CSCO】 using Python through a data analysis and machine learning approach. From data collection to model building and evaluation, we have covered the essential steps involved in this process.
