How to back test your portfolio for free

I have wanted to back test the performance of various portfolios for a while now.

One of the best sites I have found is https://www.portfoliovisualizer.com

You can go to https://www.portfoliovisualizer.com/backtest-portfolio to build and back test several portfolios.

For Europeans, there is also the curvo.eu backtester which I will discuss later.

My ETFs for H2 2025

We are now 6 months into 2025 and it is looking like Trump's devastating tariffs and his 'Big Beautiful Bill' is not going to be allowed to go ahead in it's entirety.

It may be that now is a good time to invest some spare cash that I may hold because it is looking like 'play time' will soon be over and the grown-ups will start to take charge of the USA soon.

Hot Tip: Crypto shares up 200+% in last month!

In the last month, the Bitcoin-oriented share ALTBG (Euro) has gained over 200% to date (11:00 BST 21-May-2025). They went up 168% in the last week!

This company has pledged to buy a large amount of BitCoin and seems to be rocketing. It often has a trading halt on it for a few hours but it is currently trading.

Warning: Marks & Spencer cyber hack - hackers now have all my customer details!

I received this email yesterday from M&S about the 'cyber incident' they suffered recently (although it seems they knew since Feb.2025!). 

It says that criminals have obtained my 'contact details, date of birth and online order history' and goes on to assure me that no usable card or payment details or passwords were obtained.

New Windows 10/11 AutoUnattend.xml generator

E2B, agFM and Ventoy allow you to use an unattend XML file with your Microsoft Window 10/11 ISO. This allows you to specify settings and components for your Windows install as well as semi- or fully-automate the install.

Previously, I have recommended the online Windows Answer File Generator (WAFG) but the site seems to no longer exist...

Legacy Boot with persistence for Kaspersky Rescue Disk ISO 2025 using E2B (grub4dos)

Here is how to get the KRD2025 ISO to legacy boot on E2B with user file persistence and with update file persistence.

1. Download the krd.iso file and save it to \_ISO\LINUX folder as KRD2025.iso.

2. Download the Ventoy pre-made 'backend' persistence files contained within the images.zip and extract ONE of the following persistence files as a .dat file using 7zip. I tried the 2gb one.

How I made 30% in one week from the current market chaos

It is possible to buy an ETN such as £3STP or €3STE which shorts TESLA shares.

The GraniteShares 3x Short Tesla Daily ETP seeks to track the Solactive Daily Leveraged 3x Short Tesla (-3x) index. The Solactive Daily Leveraged 3x Short Tesla (-3x) index tracks the three times leveraged inverse performance of the Tesla share on a daily basis.

The ETN's TER (total expense ratio) amounts to 0.99% p.a.. The ETN replicates the performance of the underlying index synthetically with a swap. The dividends in the ETN are accumulated and reinvested in the ETF.

The GraniteShares 3x Short Tesla Daily ETP is a small ETN with 18m GBP assets under management. The ETN was launched on 29 June 2020 and is domiciled in Ireland.

GraniteShares 3x short TESLA (Ticker 3STE) is an ETN that shorts TESLA by a negative factor of x3.

As long as I have some spare cash, then using a 'short' or 'inverse' fund allows me to hedge my portfolio but without selling any shares in my portfolio.

If you use Trading 212, use the Search page and look for 'Inverse ETFs' in the sidebar under the 'ETFs' heading.

This Euro sector ETF has gone up 30% in just 6 months!

Investors have secretly been moving away from S&P 500 stocks to Euro stocks. The past, excellent performance of the S&P 500 was mainly dependent on Tech stocks and due to recent events in AI and Elon Musk and his buddy DJT, etc. investors now think that Euro stocks have been undervalued in recent years.

Can I build a long-term Global ETF portfolio to rival the S&P 500?

The S&P 500 has historically shown very good and consistent gains, however the USA is proving to be quite a volatile market this year (2025) and so a more widely diversified portfolio would seem a sensible option.

However, investing in the whole global core market - e.g. Core MSCI World (ETF SWDA with 1,300 holdings) gives us diluted performance as it contains over 1000 stocks.

Now in my current portfolio, I have cherry-picked some S&P 500 stocks by using sector S&P 500 ETFs which have shown good performance and which I believe may continue to show good performance, such as:

• Tech - e.g. IITU or XLKQ
• Communications - e.g. IUCM
• Commodities - e.g. COMM
• Finance - e.g. IUFS
• Consumer - e.g. IUCD
• Utilities - e.g. IUSU

But what if I build a portfolio based on these sectors but using specially selected global market shares instead?

Easy2Boot 2.21 released

I uploaded a new version of E2B yesterday.

Very little has changed. The main thing was to test for the presence of wmic.exe in your Windows filesystem because new installations of Windows 11 will no longer have this once standard but now deprecated Windows utility.

Wmic.exe can be added into Windows 11 using the Optional Features option...

A new Windows 11 installation may not include the WMIC utility by default. See here

Add WMIC using: Windows 11 – Settings (Winkey+I) – Apps – Optional Features – View Features – WMIC – Install
A Windows restart/reboot my be required after installing WMIC.
