How to do it in BAII plus? |

michlam14 |
i used the formula for time weighted return ((1+.1) *(1+.15))to the power of 1/2 , then subtract 1 = 12.5% why am i wrong?? |

gulfa99 |
question is 2 period return not annualized return |

gill15 |
Mich What your doing is finding the semi annual period rate essentially (1 + j)^2 = (1.1)(1.15) and solving for j. Not right. |

Just do it with $1. 1st period dollar grows to $1.10, 2nd period $1.10 goes to $1.265 |

The words here are important. If its an annual return, you use the geometric average formula. If the return is periodic, then you simply take 1 +rate s, multiply them and subtract one. |

So you multiply instead of add because these are prices and reinvested income, correct? |

chesschh |
has to be more than 25% since its reinvested |

REMINDER multiple periods for both price return and total return are calculated geometrically. |
