Why is Stockfish so good?

Stockfish utilizes a combination of minimax with alpha-beta pruning

alpha-beta pruning

Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree. It is an adversarial search algorithm used commonly for machine playing of two-player games (Tic-tac-toe, Chess, Connect 4, etc.).

How does Stockfish work so fast?

The Main one is its aggressive Alpha Beta pruning and late move reductions. To explain a bit further. AB Pruning is a search algorithm which basically cuts out the number of nodes in its search tree.
