臺灣共同基金淨資產價值的預測--類神經網路之應用

于鴻潔 Unknown Date (has links)
共同基金在台灣是一個新興的投資理財管道,根據財政部證管會的統計資料得知,臺灣的共同基金數目已由民國八十年的27個增加到八十六年的129個,其總淨值亦由77l億台幣攀升到4691.61億台幣,顯示投資的人口正以大幅度之姿向上竄升,其投資群也由早期的機構投資者、股票族逐漸漫延到社會大眾,而投資人的動機亦曲純粹增加個人的財富,進一步擴展到籌措子女的教育準備金或個人退休養老金的規劃目標。 傳統的基金績效評估方法,大部分的研究重點均著眼於以資本資產定價模型(Caftal Asset Pricing Model ,簡稱CAPM)為理論來建立績效評估指標;或者以基金經理人的選股能力(Stock Selection)與擇時能力(Market Timing)做為評估標準;近年來亦有以投資組合為基礎的持股比率分析法。以上種種的研究,大部分都是以基金淨資產價值(Net Asset Value,簡稱NAV)與市場報酬率的變化來作為整體績效的評估基準。因此,在這樣的一個基礎上,基金淨資產價值的預測對於投資人而言就變得非常重要。如果,投資人可事先預測到各個基金的淨資產價值的未來走向,再運用上述的績效評估方法來衡量其績效,那麼投資人即可更早一步得到投資的訊息,並選取在未來績效良好的基金作為投資的重點。 因此,本研究的目的乃是企圖運用類神經網路的預測能力來建構國內共同基金淨資產價值的預測模型,並和傳統統計方法做一比較。而本研究的結果證實了倒傳遞類神經網路模式,確實在臺灣共同基金之年終淨資產值的預測上,優於傳統統計方法中的線性及非線性之迴歸分析模式。

Ekonomický kapitál a cena rizika penzijního fondu / The economic capital and the price of risk in a pension fund

Čupák, Matúš January 2011 (has links)
In the present work we study the economic capital of pension funds and their possible extension into the new concept of Solvency II. The main task is to examine the risks that are characteristic for pension fund activity. We use several modified stress simulations, which we model using a virtual model of pension fund. Primarily we focus on changes in net asset value (NAV) which is used in standard formula for calculation of the solvency capital requirement (SCR). In conclusion, we evaluate the possible impact of applications Solvency II to pension funds, the resulting economic capital and solvency of modeled pension fund.
