股票評價(Stock Valuation) - 股利折現模型

Image
這邊討論的是股價(普通股)的評價，包括股利折現模型、成長機會模型與本益比模型。 1. 股利折現模型( The Dividend Discount Model, DDM ) 股票的現金流可以分為兩個部分：股利的收入及股價的變動 先來定義 Pt：第t期的每股股價 Dt：第t期的每股股利 Rs：股利折現率(或稱為股東的必要報酬率) 當下的股票現值P0 =  D1/(1+Rs)  + P1/(1+Rs) ... (1) 一年後的股票現值 P1 = D2/(1+Rs) + P2/(1+Rs) ... (2) 將(1)代入(2)可得  P0 = D1/(1+Rs) + D2/[(1+Rs) ^2] + P2/[(1+Rs)^2] 可推得 P0 = D1/(1+Rs) + D2/[(1+Rs) ^2] + D3/[(1+Rs)^3] + ... =   SIGMA(t=1, infinite)  D1/[(1+Rs)^t] 常見的股利折現模型有三種， a. 零成長型(Zero Growth) , 即D1=D2=D3=...    利用等比級數公式, a0=D1/(1+Rs), r= 1/(1+Rs)  =>  p0 = D1/Rs      [*這跟永續年金的結果相同] b. 固定成長(Constant Growth) , 即股利按固定比率ｇ成長, D2=D1*(1+g), ...    => P0 = D1/(Rs-g)    b.1這個模型又稱為戈登模型(Gordon Model)或股利成長模型(dividend growth model)         因為這個模型提供我們很好的直覺：         b.1.1 當公司宣布年底股利增加, D1上升, P0上升 b.1.2 當公司盈餘成長, g上升, P0上升         b.1.3 當資本或風險提升，Rs上升, P0下降    b.2固定成長型的資本利得率＝股利成長率, g = (P0-P1)/P0 c. 超成長型(Supernormal or Nonconstant Growth) , 即一開始公司有高成長率，幾年後才回到一般成長。 EX. yahoo公司預期未來四年有高度成長25%, 之後皆以8%穩定成長, 其折現率20%. 今發行4塊股利： 這邊P0需分為兩個部分, 一為超成長部分及穩定成長部分.

openwrt feed的使用

最近又回去看Openwrt發現feed, 來記錄一下. feed 是一個挺有趣的東西, 在Openwrt 理面它是一堆 packages 的集合,  我想應該是因為不同的 packages 可能來自不同的地方, 透過 feed 提供介面管理這些 packages. (1) where is feeds     放在 scripts/feeds (2) feeds command     update:        撿查 feeds.conf  # or feeds.conf.default       將各自的feeds下載後放到 feeds/        建立 XXX.index      list:       透過 XXX.index, 列出 feeds/ 的feeds     install:       建立symbolic link. # from feeds/XXX  to packages/feeds/XXX (3)自己建立 feeds       1. svn co svn://svn.openwrt.org/openwrt/trunk/[BRANCH]  [OPENWRT]       2. svn co svn://svn.openwrt.org/openwrt/package  [OPENWRT]/packages       3. 撰寫自己的 feeds.conf       4. >script/feeds update -a       5. >script/feeds install       6. make menuconfig        參考Openwrt 連結
