Whether you’ve chosen exactly the right spread of equities is an impossible question to answer. A better question is what you think the role of each asset class and equity holding should be and whether what you have reflects your longer term plans and appetite for risk. You also need to think about your portfolio in the context of other savings/investments, your housing situation, your partner if you have one etc. (For example, if you own a house outright and have a partner with a pension, you could take more risk than if you and single and renting.)
As pp say, with 15 years to go you are still growing your portfolio. It is too early to be moving significantly into cash/bonds/commodities. I would suggest that you give some consideration to what you plan to do on retirement- stay invested? Buy an annuity? A mix of both? If you are staying invested you need a suitable structure to your portfolio (two of the main ways to do it are by building a cash flow ladder or taking the natural yield- each needs a different approach. Lots of info online.) In essence, both approaches are ways to avoid selling shares during a downturn, which is the key risk. But at the moment this is just something to be learning and thinking about, not actioning.
Regarding the shares you hold, there is some complexity that doesn’t make immediate sense- for example, you have an ex UK fund and an additional UK income fund. It’s not that this is wrong- you may have carefully assessed exactly the proportion of Uk holdings you want and whether they are income or growth funds and this is the best way to achieve it. Or you may not, and this is just additional complexity that isn’t really serving you. As you know you are very heavy in tech- again it’s not a question of whether this is right or wrong but whether it fits your particular plan.
I disagree with PP on the need to be able to sell quickly. You’re a retail investor, not a trader, and all the evidence is that retail investors do better with buy and hold. Unless you’re a professional trader, by the time you’ve realised a crash is underway it will be too late and the likelihood is that you’ll just miss out on the recovery. That’s why (in retirement) you need to build your portfolio intentionally to allow you to wait out the dips. Again, a lot of this is personal choice- pp who was talking about selling in a downturn may have found that it worked for her, but the evidence is that it doesn’t work for most investors as you need to be able to call the bottom as well as the top. Very difficult to do. Given that we don’t know what’s round the corner, better to build a portfolio that works whatever comes. So I wouldn’t worry too much about holding funds.
On your dislike of bonds, you’re not alone. If you google “death of the 60 40 portfolio” you’ll find a lot of people who agree with you and more people relying on larger cash holdings in retirement. Again, no saying who is right or wrong on this, and by the time you retire it may all have changed again.
There is a lot of info out there- two good sources are the Meaningful Money podcast and books and the Many Happy Returns podcast. I’d spend some time thinking about your aims and the sort of approach you’d be happy with, and then start shaping the portfolio to reflect these. But until you’ve done that first stage, it’s hard to say whether what you are holding at the moment will help you achieve them. On a “finger in the air” basis, it looks ok.
Sorry what an epic!
