Building a seven-figure Stocks and Shares ISA is a challenging endeavour. But it’s not as impossible as many seem to think, especially in today’s current economic climate. After all, while volatility increases short-term risk, it also creates buying opportunities to propel a portfolio forward.

The stock market, throughout history, has always recovered from even the most dire crashes and corrections. That’s why now could be the perfect time to start building a diversified ISA for those who haven’t already started. Even more so now that new economic forecasts are becoming increasingly positive.

Finding millionaire-making shares

Small-cap stocks can be an exciting segment of the financial markets. These young businesses often have a promising product or service capable of disrupting industry titans. And investing early in a disruptive enterprise can translate into monumental wealth.

However, things are rarely this simple. Small-caps have a tendency to be constantly under financial pressure. And in most cases, out of every hundred companies, only a handful will go on to achieve their goals. Don’t forget an exciting piece of technology does not guarantee a good business model.

Fortunately, investors don’t have to touch small-caps when building a million-pound Stocks and Shares ISA. Thanks to compounding, investing in proven and established corporations for the long run can yield similar results at significantly lower volatility, risk, and uncertainty.

Building an ISA

While risk can never be eliminated entirely, high-quality larger-sized enterprises are less likely to evaporate overnight. And while the growth rate is undoubtedly slower, superior free cash flow generation paves the way for an abundance of funding for expansionary projects.

Of course, even the most cash-rich businesses have the potential to be disrupted from both internal and external sources. That’s why diversification is critical on the path to a seven-figure Stocks and Shares ISA. By owning a collection of top-notch stocks in a variety of growing industries, the impact of one firm stumbling can be offset by the success of others.

When pairing a robust portfolio construction strategy with a prudent stock-picking approach, achieving market-beating returns becomes possible – even with large-cap companies. And in the long run, that can translate into some impressive volumes of wealth.

For example, investing £650 a month at a 10% annual rate of return (a slight excess to the FTSE 100’s 8%) can reach the £1m threshold within 27 years. That’s nearly half the average working lifetime. And it may even unlock an earlier retirement.

Is this guaranteed? Of course not. As previously highlighted, companies can be disrupted. And the best firms today may not be the same tomorrow. Not to mention that stock market crashes and corrections can and do occasionally come along to throw a spanner in the works.

Nevertheless, the potential for generating a £1m ISA make these risks worth taking, in my opinion.
