人壽保險資產配置決策之研究 / The research of asset allocation strategy for life insurance industry

隨著我國壽險業資產比率快速增加,投資績效不但影響眾多保戶的權益,更影響整體經濟之安定,但面臨現今全球金融和經濟環境劇烈動盪,加上壽險同業間激烈競爭的情況,我國壽險公司如何訂定投資策略做好資產配置,對壽險公司的營運健全而言相當重要。現行保險法第一百四十六條限制壽險公司的投資上限,但法令限制對壽險公司資產配置的影響為何,本研究將透過Markowitz的平均數-變異數投資組合模式對我國整體壽險業及國泰人壽、南山人壽、新光人壽及富邦人壽探討之;並以夏普指數、崔納指數及詹森指數,評估上述四家壽險公司之資金運用績效;另藉由分析壽險業之資金成本是否低於實際投資率,以達成研究壽險業長期資產配置之穩健度。
本研究主要結論如下:1.運用Markowitz 投資組合模型所推導出的效率前緣,以最大Sharpe Measure評估,不受法令限制下所建立之最佳投資組合,較有受法令限制下所建立之最佳投資組合的期望報酬率高,且分散風險的效果較佳。2.整體壽險業及前四大壽險公司之實際投資報酬率皆低於其實際投資組合之期望報酬,顯示壽險業於資金運用的靈活度及績效性有改善的空間。3.以績效評估指標求出前四大壽險公司的資金運用績效,發現新光人壽在此三項評估指標皆位居最後;國泰人壽在評估中皆名列前茅。4.新光人壽的平均實際報酬率低於平均資金成本,應控管好資金成本並加強投資組合之績效;富邦人壽平均實際報酬率高過平均資金成本最多,顯示富邦人壽在資金成本控管及投資績效有良好之表現。整體壽險業的實際報酬率亦高於平均資金成本,顯示我國壽險業於營運狀況正常。 / With the life insurance companies’ assets ratio rapidly increasing, the investment performances affect not only the right of a number of policy holders, but also affect the economic stability. However, facing the dynamic global financial and economic environment and the keen competition in the domestic life insurance industry, the life insurance companies need to adopt the proper investment strategy. Law of Insurance 146th p restricts the investment upper limit of the life insurance company. This research will use Markowitz MV model to discuss the influence of this investment restriction on life insurance companies’ asset allocation by the samples of Life industry, Cathay Life Insurance, Nan Shan Life Insurance, Shin Kong Life Insurance, and Fubon Life Insurance, and evaluate the performances of these four life insurance companies by Sharpe ratio, Treynor ratio, and Jensen’s measure. This research also analyze the cost of capital and real rate of return of these companies to examine the stability of life insurance industry’s long term asset allocation.
The conclusions of this research are as follows: 1.Evaluated by the Markowitz efficient frontier and the Sharpe measure, there is the higher expected rate of return and better diversification with no investment restriction. 2.The actual rates of return of the life insurance industry and the above four life insurance companies are below the expected rates of returns of their portfolio evaluated be the Sharpe measure, which means the life insurance industry need to prove their capital allocation. 3. Comparing the performance of the life insurance companies by the performance indicator, we find the then Shin Kong Life Insurance is the last, while Cathay Life Insurance has a good score. 4. We also find the real rate of return of Shin Kong Life Insurance is lower than its cost of capital, which means Shin Kong Life Insurance need to adjust its cost of capital and the investment performance. Meanwhile, Fubon Life Insurance is the excellent in controlling the cost of capital and investment. The real rate of return of the Life insurance industry is higher than its cost of capital, and that shows the Life insurance industry has normal operation.
