Detecting V-shaped stock price reversals in standard #SQL is cumbersome because it requires comparing neighboring rows, grouping consecutive price movements, and filtering those groups to identify the pattern. MATCH_RECOGNIZE simplifies this by letting you define the V-shaped trend directly as a sequence of pattern states, making the analysis more concise and intuitive.
