How I’d invest a £20,000 Stocks and Shares ISA to build wealth

With an eye on building wealth over the long term, I think owning shares in blue-chip companies makes sense. I use the Stocks and Shares ISA to benefit from both the growth and income potential of some of the country’s leading companies.

If I had a spare £20,000 to invest in an ISA today, this is how I would do it.

Set investment strategy

Different investors each have their own goals, risk tolerance, and investment style.

So my first step was to decide what I wanted and achieve. I am a long-term investor. But what is my time here? Investing based on my annual income target three or five years from now could lead me to a different choice than happily parking £20,000 in a Stocks and Shares ISA today and leaving it for decades.

Growth or income

Next I will consider what is the balance between growth and income shares. I like to compound dividends and holding a Stocks and Shares ISA with a capital of £20,000 can be a good platform for this.

So I would probably tilt the ISA towards income sharing, with perhaps a quarter or a fifth of the allocation being more growth focused.

The income sharing I have recently bought is included Vodafone and Dunelm. On the growth front, I am now eyeing shares included Alphabetthat if I had a spare £20,000 to invest in an ISA today, it would definitely be on my shopping list.

Apply risk management principles

There are two basic elements to how I can use a Stocks and Shares ISA as part of my approach to wealth building.

One is to invest in stocks that provide a positive return on investment, whether through share price growth, dividends, or a combination of both. Another important element is to avoid losing money on investments.

As billionaire investor Warren Buffett puts it, “rule number one: never lose money. Rule number two: don’t forget rule number one“. That is easier said than done, but we can at least try to drive these results by applying some basic but important risk management principles.

For example, like Buffett, I will diversify my investments in several companies. £20,000 is enough money to allow me to do this. Also like Buffett, I will stick to companies I feel I understand and can assess.

Find a company to buy

In the long run, as Buffett has shown time and time again, building wealth through investing isn’t just about buying big businesses. It also depends on the purchase at an attractive price.

It may take time and I will be patient. I wouldn’t rush to put money in an ISA to work. Instead, I will spend time creating a list of businesses that I feel have good characteristics, such as a competitive advantage in an industry with strong customer demand. I will then look for opportunities to add these companies to my Stocks and Shares ISA at the right price.
