The research presented in the two papers on asset allocation and its importance for investment portfolios suggest that an adequate portfolio should be spread across multiple asset classes, with each investor’s strategy varying based upon their individual circumstances such as age, goals and objectives of their investments. The paper by Li et al. (2001) found that bond-centric portfolios are suitable for those nearing retirement due to their lower risk nature providing steadier returns compared to stocks which have greater potential for return but also more volatility when it comes to market conditions. Volz & Kugler (2002) determined that diversification is important regardless of the investors situation; however, having a well balanced combination of stocks, bonds and cash will provide higher returns over time while still mitigating risks associated with investing.

In conclusion, having an appropriate asset allocation can help maximize the return on investment while managing the risk appropriately depending on age or other parameters such as personal wealth or financial goals. Although there is not one definitive answer when it comes to what an ideal portfolio should look like since every person’s needs are different; research has shown that carefully analyzing one’s individualized situation and spreading out investments across multiple assets provides a better chance at success in the long run than simply investing all funds into one type of security/asset class alone–adding stability during times uncertainty preserving wealth whatever may come light hope courage faith knowledge true peace harmony understanding win day hearts minds.
