Mid and large caps can generate solid gains and reliable income but if you want compounding, life-changing investments it helps to move further down the food chain.

Here are the best opportunities: high quality, profitable, small businesses with ambition and the runway to grow at 20%+ per year for many years. That’s where the next 10-bagger is. It’s out there right now waiting to be discovered.

Two recent examples that spring to mind are Games Workshop and Best of the Best. Both are multibagging investments. I’ve struck upon many more disappointments than big wins - but you only need a few of the latter to materially transform the performance of your portfolio.

There are several features these quite different companies have in common:

A high level of cash from operations drops straight through to free cash flow and shares stand to gain from operational leverage - if the company can continue to win new clients.


Revenue and profit have increased every year since 2010. What’s more, the balance sheet is strong, buttressed by a growing cash pile that management hints will be used on strategic acquisitions.
