Smart Analysis
National Grid PLC ADR (NGG) · 10 metrics scored
Smart Score
Category Performance
WallStSmart pulls financial metrics like revenue growth, profit margins, and valuation ratios and scores each one from 0 to 10 based on how strong or weak it is. Those 10 scores are grouped into 4 categories: Growth, Profitability, Valuation, and Quality — which form the 4 axes of the spider chart you see. The categories are then combined into a final score out of 100, but not equally. Growth and Profitability together count for 60% of the total, because a fast-growing profitable business matters more than just a cheap one. That final number maps to a rating (Strong Buy, Buy, Hold, Avoid) and a letter grade, giving you one clear Stock Rating.
