Use case

How can private equity firms monitor a portfolio company's competitive position between board meetings?

The same outside-in metrics used in diligence can be tracked weekly after close: competitor pricing, discounting, range changes and distribution. This gives an independent view of the value-creation plan (is the price increase holding, are competitors responding, is the brand gaining shelf space) without waiting for monthly management reporting.

What to track

  • Competitor price moves in the portfolio company's key categories.
  • Promotional intensity versus the plan and versus competitors.
  • Share of shelf at the retailers that matter most.
  • New-product flow for the company and its rivals.

Metrics used

  • Matched-SKU inflation: The price change of identical products observed in both periods, which isolates true price moves from changes in product mix.
  • Markdown breadth: The share of a brand's or retailer's live products that are selling below their full price at a point in time.
  • Share of shelf (online): A brand's share of the products a retailer lists in a category, measured on the retailer's website.
  • New-product share: The percentage of a brand's live assortment that was first seen within a recent window, such as the last 13 weeks.

How each measure is built: methodology.
