2018-05-20 21:11A stock value is three times than last year. calculate the continuously compounded return over the period: A 18.2%. B 69.3%. C 110.0%. 這個(gè)用計(jì)算器怎么按?我假設(shè)起初是1,期末是3,3-1/1=2,2,2nd,ex次方,-1,最后等于6.389

An investor invested $10,000 into an account five years ago. Today, the account value is $18,682. What is the investor′s annual rate of return on a continuously compounded basis? A 12.50%. B 11.33%. C 13.31%.,,,,,還有這道題,也是這樣的。13.31%求出來(lái)之后怎么處理?是讓e的r次方-1=13.31%嗎?還是r=13.31%,求e的r次方-1.。。。。。。。。。。。。。。。If the price of a stock goes from $15.00 to $16.20 in one year, the continuously compounded rate of return is closest to: A 8.33%. B 7.70%. C 8.00%.、。。。。。。還有這道題也是,e的r次方-1=8%,求r,還是r=8%,求e的r次方-1=???

同學(xué)你好,從性質(zhì)上區(qū)分,r是年利率,e的r次方-1是連續(xù)復(fù)利。

對(duì),我跟你想的一樣,可是另一位老師說(shuō)e的r次方-1=13.31%,反求r才行
-
追問(wèn)
反求r的話(huà)不就成了求年利率了嗎?這三道題都是問(wèn)the continuously compounded rate of return is closest to,

同學(xué)你好,經(jīng)過(guò)詢(xún)問(wèn),EAR=e的r次方-1,這是連續(xù)復(fù)利下的有效年利率,而r是我們要求的連續(xù)復(fù)利。這個(gè)地方確實(shí)容易弄混。

追問(wèn)
那這道題應(yīng)該怎么做呢?
-
追答
根據(jù)第一句話(huà),得出EAR(即e的r次方-1)=200%,之后用計(jì)算器求出r,這個(gè)r就是要求的連續(xù)復(fù)利。

算出來(lái)是1.098?
-
追答
是的,e的r次方=3,那么ln3=r,用計(jì)算器代入,得到1.098,即109.8%,約等于110%,選C。
