An analyst reports that a stock's earnings per share were Rs 12 last year and Rs 15 this year, and then says a 25% rise in EPS is certain to continue next year. Which research weakness does this best illustrate?

The statement shows extrapolation of past growth without supporting evidence. The 25% rise in EPS is arithmetically correct, but treating it as certain to continue ignores future drivers and risks, so the forecast lacks a reasoned basis.

  1. AExtrapolating past growth without supporting evidenceCorrect
  2. BUse of primary data
  3. CUse of a top-down approach
  4. DUsing a sampling technique

Explanation

Growth is (15-12)/12 = 25%, so the arithmetic is right. The flaw is asserting that it is certain to continue, which projects history forward without evidence on drivers or risks.
