Solution
Answer: Vertical Analysis
Common size statements convert each item in a financial statement into a percentage of a common base (e.g., each Balance Sheet item as a % of total assets, or each P&L item as a % of net sales). Because everything is expressed as a proportion rather than an absolute figure, the technique works for:
Intra-firm comparison — tracking the same company's percentage figures across different years to spot structural trends.
Inter-firm comparison — comparing companies of different sizes for the same year (or across years), since percentages neutralize the effect of differing scale.
This technique is called "vertical" analysis because the comparison is done within a single column/year, moving down the statement, each item is compared vertically to the base figure from that same period.
