Abstract The cash ‡ows of growth stocks are particularly sensitive to temporary movements in aggregate stock prices (driven by movements in the equity risk premium), while the cash ‡ows of value stocks are particularly sensitive to permanent movements in aggregate stock prices (driven by market-wide shocks to cash ‡ows.) Thus the high betas of growth stocks with the market’s discount-rate shocks, and of value stocks with the market’scash-‡ow shocks, are determined by the cash-‡ow fundamentals of growth and value companies.
