Is there anything we can take away from this insight? Absolutely. Here are two important lessons.

Low-risk investing

For starters, the common theme here seems to be a focus on low-risk, large-cap investing. ISA millionaires' portfolios are not filled with high-risk assets. All of the stocks listed above are well-known FTSE 100 companies. Similarly, the majority of those funds invest mainly in large-cap companies.

Capital preservation is a fundamental concept when it comes to building long-term wealth from the stock market. As Warren Buffett often stresses, it's vital that you don't lose money when investing. That's where large-cap stocks can play a key role, as they're generally less risky than smaller companies. As a result, a low-risk investment strategy that focuses on stable, secure businesses can generate impressive returns over the long term.

Income focus

Second, there appears to be a strong focus on dividends among ISA millionaires. All of those stocks pay their shareholders large dividends, and most of those funds have a focus on income as well. This is an important point that shouldn't be ignored.

While many investors focus on capital gains, it's the dividends you earn, and the reinvestment of these dividends, that will often provide the bulk of your total investment returns over the long term. For example, for the 20-year period to the end of 2016, the FTSE 100 returned 73% in capital appreciation terms, according to Bloomberg. However, with reinvested dividends added in, the total return was 214%. Dividends are an amazing compounding tool when reinvested as they allow you to earn a return on your previous returns. Over time, this can result in the exponential growth of your capital.

The moral of the story here is that investing doesn't need to be complicated. To build up an impressive seven-figure ISA portfolio, play it safe with low-risk large-cap stocks, reinvest your dividends, and stick it out for the long term.
