Vectorized NumPy is much faster than a Python loop for large arrays because it uses SIMD and homogeneous memory layout. Vectorization operates on whole arrays with a single instruction instead of looping over individual elements. NumPy enables vectorization by storing homogeneous arrays in contiguous memory and delegating arithmetic to SIMD CPU instructions. For high-frequency trading datasets, vectorization can determine whether risk calculations or signal pipelines finish within a trading window.
