Against street estimates

How AMBA's reported EPS compared with analyst consensus. Street estimates are single-source vendor consensus (yfinance). Actuals are vendor consensus-basis EPS (often non-GAAP); edgarEps is GAAP diluted from filings — disputed flags large disagreement only. A consensus out of line with the name's earlier estimates (opposite sign to all of them and over 3x their size) is not graded. EPS only.
