16.4 Stock Return Response Modeling
Valuation model
MarketCapit=∞∑T=t(11+rit)T−tE(CFT)
Equivalently,
MarketCapit=(1+Eretit)MarketCapit−1+∞∑T=t(11+rit)T−tΔE(CFiT)
where0
Eret = expected rate of return for an asset
ΔE(CFiT) = change in the expected cash flows
Hence, the stock return can be written as
StockReturnit=
