Damien’s £50,000 portfolio performance

5 min Read Published: 30 Aug 2023

A key part of my 80-20 Investor service is to help people invest their own money successfully and profitably, which is why I invest £50,000 of my own money live for the benefit of 80-20 Investor members. That means that I publish every trade along with my reasonings in any easy to follow format. I also publicly analyse my outperformance. No other investment expert or commentator invests their money live publicly. In this article I will show you how I have outperformed the market, passive investment strategies and professional fund managers. I will tell you how I turned £50,000 into nearly £60,000 with a two year 80-20 Investor membership. I will also show you how I made a 50.49% profit (that's £25,245 profit) after eight years and how you could have too with only a few minutes of your time every now and then.

Damien's £50,000 portfolio performance after a two-year membership

In March 2015 I decided to invest £50,000 of my own money using 80-20 Investor. The purpose was firstly to show how you can use 80-20 Investor to invest and outperform the market with only a few minutes effort every now and then. I also wanted to prove the value of an 80-20 Investor membership. The biennial membership costs £288 which equates to just £12 a month. 80-20 Investor members receive:

  • updated fund shortlists based upon our momentum algorithm
  • weekly and monthly market commentary and analysis
  • in-depth research articles to help members invest
  • tools and heatmaps
  • stop loss alerts

That alone is worth the subscription as members regularly tell me. However by investing £50,000 of my own money I wanted to show in pounds and pence that a membership to 80-20 Investor is worth every penny. No other investment commentator, journalist or research provider invests their own money in this way for fear of failing. This is a sorry state of affairs and is precisely why I committed to openly running my own portfolio for 80-20 Investor members to see. It was a bold move particularly as when I started investing my money the markets were near all-time highs and everyone was predicting an imminent market crash.

Since I began investing I have periodically changed my portfolio using the fund suggestions provided by the 80-20 Investor algorithm and associated research. I always disclose the changes at the time they are made.

The best £288 you'll ever spend?

During the two year membership I used the information provided to outperform the market and professional investors while not taking excessive risks. Typically only around 50-60% of the portfolio is invested in equities. In just two years I produced a profit of 18.83% despite the various crises we experienced including a Greek crisis, a Chinese economic slowdown, a commodity crisis, the Brexit vote and Donald Trump's surprise election win. I managed to turn my original £50,000 into £59,365 in just two years.

Coincidentally I made the money back on my initial subscription within weeks of starting my £50,000 investment portfolio. In addition in the aftermath of the Brexit vote I made 5.35% in just 2 days while the FTSE 100 fell by 5.62%! The table below shows how my £50,000 portfolio performed over the two years versus:

  • my portfolio's benchmark (calculated by using the average return for each sector in which my portfolio invested)
  • the average professionally run multi-asset fund with comparable equity content
  • APCIM benchmarks (the equivalent an investment bank would have made a rich person who could afford their services)
  • AFI cautious and AFI balanced indices (which show how much the typical financial adviser would have made you)
  • Vanguard benchmark – what the equivalent passive Vanguard portfolio achieved using the same equity content
Name 2 yr profit % Sharpe ratio Volatility
50k challenge 18.73 0.48 1.28
Passive Vanguard benchmark (passive strategy) 15.73 0.39 1.3
AFI Balanced (IFA's balanced portfolio) 14.35 0.37 1.12
Average managed multi-asset fund (fund manager) 12.25 0.23 1.03
AFI Cautious (IFA's cautious portfolio) 10.57 0.22 n/a
ARC Sterling Balanced Asset (Investment bank) 9.33 0.01 n/a

The takeaway from the above table is that without taken undue risk (shown by the volatility figure) my £50,000 portfolio achieved the best return. In addition, the extra investment risk I took was rewarded by an increased return when compared to the risks taken by other strategies (illustrated my portfolio having the highest sharpe ratio). Other strategies' risk/return balance is inferior to my portfolio.

Profit from a 2 year 80-20 Investor membership

The table below shows how much extra profit (net of the 80-20 membership fee and fund charges) I made using 80-20 Investor vs other strategies. Don't forget that the 80-20 Investor membership is a fixed price and so doesn't increase just because you invest more money. All figures are net of fund fees and the cost of a biennial 80-20 Investor membership:

Amount invested
£20,000 £50,000 £75,000 £100,000 £250,000
£50k challenge overall profit £3,458 £9,077 £13,760 £18,442 £46,537
extra profit over a Passive Vanguard benchmark £312 £1,212 £1,962 £2,712 £7,212
extra profit over a balanced IFA portfolio (AFI Balanced Index) £588 £1,902 £2,997 £4,092 £10,662
extra profit over an Average managed multi-asset fund £1,008 £2,952 £4,572 £6,192 £15,912
extra profit over the cautious IFA portfolio (AFI Cautious Index) £1,344 £3,792 £5,832 £7,872 £20,112
extra profit over an Investment Bank Discretionary Portfolio (ARC Sterling Balanced Asset Index) £1,592 £4,412 £6,762 £9,112 £23,212

The other thing to bear in mind is that IFAs will typically charge you an extra 0.75% to 1% of your portfolio size each year to run your money which the above figures do not take into account. So their performance is overstated. In addition not only did the passive strategy have a higher volatility but it had larger drawdowns (falls) than my portfolio.

My outperformance after 8 years

I first started running my portfolio back in March 2015 and I have now passed the 8th anniversary of doing so. That is a long time period with which to demonstrate my track record of managing my money using 80-20 Investor. This period included challenging market-moving events such as the Brexit referendum, the US election, the US-China trade war, the coronavirus outbreak and the war in Ukraine. The table below shows how my £50,000 portfolio performed over the eight years (up to the end of August 2023) versus the same benchmarks I used earlier. It is now worth £75,245.

Name March 2015 to August 2023 profit % Sharpe ratio (annualised) Volatility (annualised)
50k challenge 50.49 0.14 9.04
Average professionally balanced managed multi-asset fund (Mixed Investment 40%-85% Shares Index) 43.20 0.08 9.29
Passive Vanguard benchmark (passive strategy) 38.99 0.04 8.88
AFI Balanced (IFA's balanced portfolio) 38.43 0.03 9.38
AFI Cautious (IFA's cautious portfolio) 27.03 0.00 7.38

My outperformance has been achieved by following the asset allocation suggested by the 80-20 Investor algorithm and having a concentrated portfolio of funds. For example ahead of the EU referendum I reduced my exposure to UK and European equities, which was a bold but ultimately correct call. Following the pandemic I rotated into technology funds and then into value funds to take advantage of the shifts in consumer behaviour. In 2022, I reduced my equity exposure and removed my exposure to bonds almost entirely ahead of both markets slumping. Of course, as you can appreciate, there is no performance guarantee with 80-20 Investor as returns are dependent upon market conditions.

But it doesn't stop there…
