The recent stock market turmoil has granted investors a perfect opportunity to establish a five-figure passive income. In fact, investing as little as £350 each month in top-notch British stocks could be the only thing standing between an individual and a £39,200 passive salary.

This undoubtedly sounds farfetched. But it’s more realistic than most would believe, thanks to the power of compounding. Investing each month consistently into a diverse collection of high-quality businesses can unlock tremendous wealth with even relatively modest sums of capital. Let’s explore how.

Focus on the long term

Everyone understandably wants to get rich as quick as possible. And there have been some cases where one well-timed investment resulted in transformational wealth being created seemingly overnight. However, such occurrences are extremely rare and arguably akin to buying £350 worth of national lottery tickets each month.

Given that the odds of winning the lottery are close to one in 45 million, that doesn’t sound like prudent investing. Fortunately, investors with more patience don’t have to expose themselves to such extreme risk.

It’s easy to forget, but underneath every stock lies a business. In fact, the underlying firm is precisely where shares derive their value. Each share is a claim on corporate earnings. And the better the company, the larger the earnings, and the higher the stock price.

But just like wealth, businesses don’t spontaneously become global industry leaders. It takes time, during which many challenges will arise. The trick to becoming a successful passive income investor is spotting the firms with the right talent, resources, and competitive edge to overcome these hurdles.

So while most of the investing world is getting its knickers in a twist over missed earnings targets, intelligent investors are busy asking, why? Is there a thesis-changing problem that has been revealed? Or is this just a minor speed bump along the road to industry dominance?

Creating a passive income portfolio

Diversification is a critical aspect of the portfolio construction process. As recent economic headwinds have revealed, businesses aren’t only disrupted by internal operations. Unpredictable external forces can enormously impact cash flow with little recourse available.

That’s why owning a diverse group of companies operating in different industries and geographies is paramount to keeping risk in check. Should one firm be brought to its knees — as travel companies were in 2020 — the other portfolio positions can help minimise the damage.

Even if an investor only manages to match the 11% average return of the FTSE 250, that’s still more than enough to generate a sizable passive income.

In fact, at 11%, investing £350 a month for 30 years translates into a portfolio worth £981,582. And following the 4% withdrawal rule, this delivers an income stream of £39,263.24 each year.

Obviously, there are no guarantees here. The stock market does occasionally decide to throw a tantrum. And while it has historically always recovered before reaching new heights, a poorly timed market crash or correction can send even a diversified portfolio into a tailspin.

In other words, investors may end up with less than expected after three decades of patiently waiting. But given the potential rewards, unlike the lottery, this is a risk worth taking. At least, that’s what I think.
