Table 2 presents OLS estimates of the 1974-88 year-by-year cross- sectional regressions (5) and (6) and an across-years significance test.12 Table 2 estimates are for firms having data for all 12 fundamental signals (roughly 140-180 firms per year). This restricted sample is not representative; for example, it includes only companies with R&D expenditures. In table 3 we report estimates from a much larger sample, roughly 500-600 firms per year, where the data requirements for R&D, Provision for Doubtful Receivables, and Order Backlog were re- moved. These three fundamentals caused the largest loss of firms in the restricted sample (e.g., Order Backlog was reported by only 35% of the sample firms). This larger sample is quite representative, including
