NettetThis property of the natural log function implies that LN (1+r) ≈ r when r is much smaller than 1 in magnitude. Why is this important? Suppose X increases by a small percentage, such as 5%. This means that it changes from X to X (1+r), where r = 0.05. Now observe: LN (X (1+r)) = LN (X) + LN (1+r) ≈ LN (X) + r
