Stocks for the Long Run

Our Founder and CIO, Mark Ellis, recently highlighted Stocks for the Long Run by Jeremy Siegel in an article on the Nutshell Growth Fund. The book offers valuable insights into the history of the stock market and the power of long-term investing. Here are some of our key takeaways...

Why you need more than just Quality & Growth.

For decades, investors have debated the best way to capture long-term equity returns. Jeremy Siegel’s Stocks for the Long Run makes a compelling case: equities remain the most powerful wealth-generating asset class, provided investors stay disciplined. With our Nutshell Growth Fund, we take this philosophy a step further by applying a systematic, multi-factor approach to Quality & Growth investing. It avoids the common pitfalls of chasing momentum, overpaying for future earnings, or riding speculative stocks up and then all the way back down. Here’s how we do it differently.

The long-term power of Growth Stocks, with discipline.

Siegel’s research confirms what many investors instinctively know: stocks outperform other asset classes over long periods, and companies that can compound earnings deliver exceptional results. However, history also shows that investors frequently get caught in the euphoria of high-growth stories, often paying too much and suffering when valuations inevitably contract.


Nutshell’s approach is to back the companies that have already won and thus avoid chasing hyped-up, unprofitable “story stocks” with uncertain futures. Instead, we focus on companies with a proven ability to generate sustainable earnings and cash flows. By systematically applying factors like quality, earnings growth, relative valuation, and momentum, we ensure we’re not just buying growth, but profitable growth at a reasonable price. This approach differentiates us as one of the best-performing growth funds available to both institutional and retail investors.

Valuation matters, avoiding the pitfalls of overpaying.

One of Siegel’s most critical findings is that even the greatest growth companies can be poor investments if purchased at excessive valuations. The market has seen this time and again. Investors who bought Cisco at >200x earnings in 2000 are still waiting to break even (capital returns), as shown in the chart below.

This is why Nutshell integrates a relative valuation discipline into our process. While some growth funds are content to “let winners run” regardless of valuation, we systematically rebalance every two weeks, taking profits when stocks become too expensive. This disciplined rebalancing aligns with institutional equity fund strategies designed to maximize long-term returns while mitigating downside risk. We believe that growth investing isn’t just about finding great companies; it’s about buying them at the right price and knowing when to trim positions. This is what allows us to compound returns over time without being exposed to excessive drawdown.

The current sell-off and geopolitical uncertainty.

We’re reminded of the common selloffs in markets through this chart of the S&P 500. There have been 26 instances where the market has sold off over 10% from a peak shown by the dots below. As we write, the S&P is nearing this territory again and the Nasdaq has breached the 10% level – used to define a correction.
