Introduction to FinLab 選股策略產生器

FinLab 選股策略產生器 is a comprehensive tool designed for quantitative analysis and stock selection. It is tailored for both professional quants and retail investors looking to enhance their investment strategies through data-driven insights. The primary purpose of FinLab 選股策略產生器 is to provide users with the ability to create, backtest, and optimize stock selection strategies using a rich dataset that includes price, fundamental, and technical indicators. This system is particularly useful for building strategies that can be systematically tested across various timeframes and conditions. For example, an investor might use FinLab 選股策略產生器 to develop a strategy that buys stocks with strong revenue growth and low valuation ratios. The tool allows the investor to pull historical financial data, apply various filters and conditions, and then backtest the strategy to see how it would have performed over the past several years. The system can handle complex strategies that incorporate multiple conditions, such as combining technical indicators with fundamental analysis.

Main Functions of FinLab 選股策略產生器

  • Data Retrieval and Management

    Example Example

    Using `data.get('price:收盤價')`, users can fetch historical closing prices of stocks. This data is stored locally and can be reused without re-downloading.

    Example Scenario

    An analyst wants to calculate the moving average of a stock's closing price over the past 60 days. They retrieve the price data and apply a rolling mean to generate the moving average.

  • Strategy Backtesting

    Example Example

    The `backtest.sim(position, resample='W')` function allows users to simulate their strategies on historical data, adjusting positions weekly.

    Example Scenario

    A trader develops a momentum strategy that buys stocks hitting new 52-week highs. They use the backtest function to see how this strategy would have performed if rebalanced every Friday.

  • Indicator Calculation

    Example Example

    Users can compute technical indicators like the RSI using `data.indicator('RSI', timeperiod=14)`.

    Example Scenario

    A trader wants to incorporate RSI into their strategy to avoid overbought conditions. They calculate the RSI for each stock and add a condition to avoid buying stocks with an RSI above 70.
