Vanguard LifeStrategy Funds
Vanguard LifeStrategy funds have become a popular option for investors offering a choice of funds with differing risk profiles to suit the needs of investors at various stages of their investment life cycle. A young investor can chooses a fund with a 100% or 80% stock allocations whereas a retiree can opt for a fund with as little as 20% equity holding.
In my post ¨Falling Out of Love With LifeStrategy Funds¨ I identify a number of characteristics of these funds which don´t make them ideal for me - such as the holding of corporate bonds, the inability to implement a drawdown strategy that varies the equity/bond ratio and the use of currency hedging. However for many investors LifeStrategy products offer reasonably priced diversified portfolios, automatic rebalancing and a choice of risk profiles to suit the stage of life of the investor.
What Are Target Date Funds?
Target Date Retirement Funds increase bond allocation with time to de-risk the portfolio as the investor approaches and enters retirement. They are well established in the USA to the extent that they form the basis of around 50% of all retirement plans. In the UK they are less mainstream but the concept has received more attention of late - all be it negative due to the criticism of the NEST auto enrollment target date fund that it has too high a bond allocation (40%) for younger investors.The concept of these funds is simple. As you get older you should be more risk averse and hold more bonds. So these funds are marketed with a range of target retirement years. You pick the Target Date Fund closest to your ideal retirement and the fund will automatically increase the bond holdings as you approach the target date.
When you are several decades away from the target date the fund will have a 80%-100% equity allocation and this gradually reduces as the target date approaches. The equity proportion will continue to reduce for 5-10 years after the target date until it stabilises at 20-30%. In effect it is an automated method of applying one of the bond/equity/age rules of thumb such as the % equity holding should be 100-your age. Vanguard Target Retirement is probably the best known UK range of funds followed by BlackRock Lifepath and Architas Birthstar.
The graph below shows the characteristics of three of the Vanguard Target Date funds - with target dates of 2015, 2020 and 2025. The investor choses his fund on the basis of when he intends to retire but can choose a more conservative portfolio (higher bond allocation) by choosing a target date earlier than his intended retirement year or a more aggressive portfolio be choosing a target date later than his intended retirement year.
So an investor who chooses the 2020 Target Date will have around a 50% stock allocation at age 65 reducing to 30% at age 75. The investor can therefor choose a target date to match his risk tolerance. The table below compares the three different target dates:-
Vanguard Portfolio Characterisitics
The Vanguard LifeStrategy and Target Date funds share many asset allocation characteristics with almost identical equity portfolios and geographic spreads. Their bond allocations are different however with the Target Date fund having a higher weighting to government bonds.Criticisms of The fund
Bonds: My preference would be for 100% government bonds in order to reduce volatility. Corporate bonds are significantly correlated with the stock market whereas government bonds are generally negatively correlated.
Hedging: The Sterling hedging of these funds is understandable as they are targeted at UK investors. However, investors who have non sterling expenses through overseas property ownership or lengthy overseas stays would probably welcome some direct exposure to dollar or Euro denominated assets. Hedging has a cost - around 0.2% so there is a price to pay in order to eliminate the effects of currency volatility. Whilst hedging has been unprofitable for UK investors over the last few years and this has adversely affected LifeStrategy performance there is evidence that historically it has been beneficial. The Brandes Institute report "Currency Hedging Programs: A Long-Term Perspective" concluded " Data covering the full period of floating exchange rates (1973-2006) showed that passive hedging programs have been costly for a U.S.-based investor (-1.8% annualized), but beneficial for an investor based in the United Kingdom (+0.9% annualized), with investors based in the other major currency countries studied seeing less long-term impact over that full period."
Geographical Allocation: LifeStrategy funds are often criticised for being UK overweight having a near 25% UK allocation compared to the UK´s global stock market share of less than 6%. Personally I think it is a reasonable compromise but there will be many others who view the UK´s prospects negatively and would wish to have a higher overseas participation.

Performance of 2025 Vanguard Target Date FundCompared With a 60/40 ETF Portfolio - Hedged and Unhedged
A DIY investor could maybe consider a 2 ETF portfolio in place of a mixed asset fund such as Vanguard LifeStrategy or Target Date Retirement Fund. The Ishares All Gilt combined with the Ishares MSCI World ETFs would suit an investor who did not want to hold corporate bonds and did not want a bias towards UK equities. The MSCI World ETF is also available Sterling hedged or unhedged. A 60/40 ETF portfolio has charges of 0.15% compared to 0.24% for the Vanguard fund.
The graph below shows the 3 year performance of hedged and unhedged Ishares 60/40 ETFs compared with the 2025 vanguard Target Retirement fund (currently 60/40 equity/bond):-
A: Vanguard Target Date 2025
B: Hedged 60/40 Ishares All Gilt/MSCI World.
C: Unhedged 60/40 Ishares All Gilt/MSCI World.
Unsurprisingly with Sterling´s post Brexit referendum decline the unhedged ETF significantly out-performed. More surprising is that the Vanguard Target Date fund offered slightly higher growth than the hedged Ishares. I was expecting poorer performance due to its UK bias and corporate bond holdings so was pleasantly surprised. This stronger performance easily outweighs Vanguard´s higher charges.
Pre-Retirement - Are Target Date Funds A Good Retirement Savings Option?
Why not? If LifeStrategy funds are a reasonable option for most investors then a Target Date version could be the ideal retirement savings product. Clearly there must be some pretty sound evidence to boost them to such popularity in the USA (not just hefty commissions!). My major concern is over the the glidepath profile:-- A 20% bond holding for maybe the first 20 to 30 years of savings is probably far too conservative and will depress growth.
- At what age is a 30% equity holding appropriate - if ever? In the era when most retirees had to purchase an annuity a high bond holding close to the target retirement date was sensible. Now a high proportion of retirees are using drawdown over a 30 to 40 year retirement and the only way for that income to last is through a portfolio containing a reasonable proportion of equities. 30% in equities maybe too little at age 75 or 80 when a couple may have to budget for another 20 or 25 years of longevity.
Post Retirement - Target Date Funds in Drawdown
Probably the most important factor when considering a Target Date for retirement income drawdown is the glidepath of the fund - how quickly it reduces its equity holdings. Although choice of the target date of the fund can allow some customising of the glidepath the result in the case of Vanguard is always the same - a 70% bond 30% equity allocation 7 years after the target date. So a retiree choosing a target date to coincide with his 65th birthday will have a 30% equity allocation at 72 years of age. Is this playing it too safe to guarantee potentially 30+ years of income?The graph below attempts to provide guidance on this. A 40 year retirement is assumed for three investment cases and the maximum annual safe income is shown for bond allocations varying from 0% (100% equity) to 100% (0% equity):-
- A US based retiree with a fund based upon total US stock market and intermediate treasury bonds
- A UK retiree with total UK stock market and 10 year gilts
- A UK retiree with a 25% UK stocks, 44% US stocks, 31% global (ex UK and US) and 10 year gilts
