Beginning investors can have a tough time trying to figure out where to put their money. Often, that leads to investing in mutual funds to allow professionals to take up the task. But what if there was a way to invest like a mutual fund, but pay none of the fees?

Investors might want to consider taking a look at Castle Focus Fund's (NASDAQMUTFUND:MOATX) mutual fund dedicated to finding companies with the widest moats -- or sustainable competitive advantages -- out there, and buying shares of those companies.  

The fund has been around for just a little over three years, and as you might expect in a bull market, it is underperforming by a wide-margin. But when you look at how the investment strategy has worked over the years for portfolio manager Robert Mark, it has returned 250% since 1999, versus the S&P 500's return of just 48%.

Many of the names you might be familiar with are in the fund, but you'll probably be surprised to find that the stock with the largest allocation in the fund is beer maker Molson Coors (NYSE:TAP). To find out why Coors owns that coveted position, check out the following video and see whether Coors deserves a spot in your own portfolio.
