The team of four co-managers aims to grow an investment by investing in businesses with exceptional growth potential and holding them for long enough to reap the rewards. We like the managers' long-term, disciplined investment process and think they are well equipped to succeed in navigating the world's largest stock market. The managers believe few companies are capable of delivering exceptional returns over the long run, so they run a relatively concentrated fund of between 30 and 50 stocks, which can increase risk.

They believe that companies with resilient business models make for good long-term investments and that corporate culture can be a key component of company performance and ultimately investor returns, although of course there are no guarantees. The managers have also identified a number of powerful trends they believe to be occurring across the economy. Many of the businesses driving these trends are highly innovative and disrupt old ways of doing things. The fund mainly invests in larger companies but also has a small amount in smaller companies, which are higher-risk.

It is important to remember the managers run a low turnover, high concentrated, long-term portfolio. This means performance can be materially different to the market and can lead to periods of heightened volatility.

The fund aims to deliver long-term growth by investing in unloved US smaller companies, with the potential to come back into favour or recover in future. We think this is a great way to invest in smaller companies with high growth potential in one of the world's most innovative markets, although investing in smaller companies is a higher risk approach.

We like Lauren Romeo’s disciplined, valuation led investment approach. She has close to 30 years’ investment experience investing in the US market and she has a strong support network of analysts as well as the firm’s founder Chuck Royce. Romeo runs a relatively concentrated fund which can increase risk.

This fund aims to track the performance of the FTSE USA Index. It invests in 606 mostly large American companies.

This fund invests in most companies in the FTSE USA Index in proportion to each company's size. The larger the company, the larger its impact on the index. Smaller businesses that make up a very small part of the index are sometimes not held in the fund as they can be more difficult or expensive to buy and sell. This helps to keep costs lower.

The fund's tracked the index tightly and efficiently over both the short and longer term, losing little value to annual charges. We think it's a great option for low-cost exposure to the US stock market.

The fund aims to deliver long-term growth by investing in smaller companies based in the US. We think this is a great way to invest in smaller companies with high growth potential in one of the world's most innovative markets, although investing in smaller companies is a higher risk approach.

We like Cormac Weldon's clear, disciplined investment approach, which has served the fund well since launch. He has almost 20 years' experience of investing in the US and is supported by a strong team of analysts. Weldon runs a relatively concentrated fund investing in 50-70 companies out of the thousands that make up the benchmark, which can increase risk.

Since joining Artemis to launch the fund in October 2014, Weldon has delivered attractive returns for investors. Our analysis suggests Weldon's stock picking has added value for the fund. Please remember past performance is not a guide to future returns.
