賦權基本面指標型投資模型之建構與績效分析

本研究旨在建立因子選股投資策略之模型。在財報中挑選了五項指標進行討論,並建立三種投資模型:單因子模型,等權重雙因子模型與不等權重雙因子模型。 單因子組合中將各項因子獨立回測後比較,PB 為最佳因子指標。並以市值篩選樣本池後重新回測,得到更優之年化報酬率與風險值。 在雙因子等權重模型中,本研究將 5 項因子指標兩項進行組合,共計 10 項組合,並在優化上針對投資週期更換為季報後一日交易、剔除表現較差的因子 EPS。優化後單因子最佳組合為 ROE,雙因子最佳組合為 ROE+PB。 在雙因子不等權重模型中,以二分逼近法找最佳比重,經過回測後最佳年化報酬率組合為 ROA+PB 並配與權重 2:3,年化報酬率高達 29.76%,為本研究最佳選股模型。

Vitas: Digital Therapy Based on a Combination of Binaural Beats and Autonomous Sensory Meridian Response (ASMR) to Reduce Stress in Gen Z Students

Vitas is a combination of binaural beats (BB) with background white noise (ASMR) as accompanying music without reducing the quality of brain stimulation and is able to stimulate the left and right brain while synchronizing brain waves so that it can be used as a media for coping with stress for Gen Z students. To find out the effect Vitas in reducing stress levels, research was conducted on high school students belonging to Gen Z. This research aims to measure the stress index of students belonging to Gen Z, then find the effect of the combination of binaural beats (BB) and ASMR on students'stress levels, and finding the best audio combination to reduce stress levels as a coping mechanism. This research uses a quantitative approach with a quasi-experimental design using a one group pre-test-post-test design scheme. The sample in this study consisted of 105 students who were divided into seven treatment groups to listen to a combination of BB and ASMR with different bandwidths. Stress levels were measured using the DASS 42 stress section questionnaire which has been tested for reliability and validity. The results of the student stress index were 16.26 in the mild stress category. There was a significant difference between the negative group, the alpha + ASMR group and the positive group with a T-Paired test result of less than 0.05. Based on the results of the Post Hoc LSD test, it was found that the combination of binaural beats alpha (12hz) + ASMR was the best combination for reducing stress in students.These findings were developed into a digital therapy application product called "Vitas" as an alternative media for coping with stress for Gen Z.
