Thenumpy.floor()method returns the floor of the supplied array, element-wise. The floor of the numberxis the largest integeri, such thati<=x. I've also written an article onhow to round a float to N decimal places in Python.
# Define portfolio weights (e.g., 50% AAPL and 50% MSFT) weights = np.array([0.5, 0.5]) # Calculate portfolio returns portfolio_returns = daily_returns.dot(weights) # Calculate cumulative returns for each asset cumulative_returns = (1 + daily_returns).cumprod() - 1 # Calculate Sharpe ...
