A Stocks and Shares ISA is one of the most powerful tools in a British investor’s arsenal. Apart from granting access to stock markets around the world, all capital gains and dividends can be enjoyed without HMRC knocking on the door. And subsequently, reaching £100,000 for the first time becomes far easier without taxes disrupting the wealth-building process.

But how exactly can investors reach this milestone? Let’s explore the options.

The paths to a £100k portfolio

Investing involves a lot of diverse opinions and strategies. Arguably, one of the most popular in 2024 is capitalising on index trackers. These low-cost funds enable investors to mimic the returns of a benchmark index without having to worry about research, portfolio management, or diversification.

The FTSE 100 is often a popular destination for those seeking a more stable journey, with the S&P 500 offering greater returns at the cost of higher volatility. Looking at the latter, investors have enjoyed an average return of around 10% per year. And investing £500 a month at this rate, would build a £100k portfolio in under a decade.

While having a six-figure portfolio is undoubtedly exciting, waiting around for 10 years doesn’t exactly sound thrilling. And not everyone has the luxury to contribute more capital each month. Fortunately, there is an alternative way to accelerate the wealth-building process.

Stocking picking for higher returns

Index investing provides a near-hands-off experience. And it’s a proven strategy for building long-term wealth. However, since investors are simply copying an index, it’s impossible to achieve market-beating returns.

So, instead of owning such a basket of companies, investors can construct their own portfolios from individual businesses. By only buying top-notch firms at sensible prices, it’s possible to unlock superior gains, although it’s not guaranteed. That’s how legendary investors like Warren Buffett have built staggering fortunes. And even if an investor only musters an extra 2%, that can make a massive difference to wealth in the long run.

Of course, the opposite can also happen. Making bad investment decisions can potentially compromise a portfolio to the point where it not only loses to the market but ends up destroying wealth. In other words, stock picking offers the potential for greater returns at the cost of higher risk.

A top stock to buy now?

Continuing with the S&P 500, the US index has had a terrific run so far this year, rising by more than 15%. This stellar performance has been driven by a lot of factors. But shares of Nvidia (NASDAQ:NVDA) definitely had a significant role. After all, it’s the second-largest stock in the index, and it’s up by almost 160% over the same period!

To put that into perspective, a £1,000 investment in January would now be worth £2,600. These gains are being driven by the excitement surrounding AI. Since Nvidia’s products are a critical component to powering AI models, it’s no surprise that the company has made a killing.

But while the underlying business is undoubtedly top-notch, the current share price demands a pretty lofty premium. So much so that in the last three months, insiders, including the CEO, have been selling their shares by the millions. That’s a signal that the share price has got a bit too far ahead of itself. And therefore, it may be worthwhile looking elsewhere for opportunities right now.

Zaven Boyrazian has no position in any of the shares mentioned. The Motley Fool UK has recommended Nvidia.

Here at The Motley Fool we believe that considering a diverse range of insights makes us better investors.
