Capital with consequences needs more than passive exposure.
Shell Capital manages ASYMMETRY® Managed Portfolios for business owners, physicians, families, and private clients with meaningful capital at stake.
We define downside before taking risk. We size exposure by volatility. We exit when the risk/reward changes. And we coordinate the portfolio with the full private wealth picture — tax, estate, protection, retirement income, succession, and legacy.
Mike Shell manages the portfolio. Christi Shell coordinates the wealth strategy. Your capital stays in your name, custodied at Goldman Sachs Custody Solutions.
Shell Capital Management, LLC is a registered investment adviser founded in 2004. Every position has a predefined exit before it’s entered. Position size is governed by volatility, not conviction. Drawdown is controlled at the portfolio level, because the math of loss is unforgiving: a 50% decline requires a 100% gain to recover. We’d rather never need the 100%.
Who we serve
Business owners before and after the sale of a company. Physicians and practice owners navigating transactions. Executives with concentrated equity, retirees, trustees, and families whose capital carries consequences — people who’ve built something worth protecting. The common thread isn’t occupation. It’s consequence. Most of our communication is in writing, by design: it produces clearer thinking, better decisions, and a complete record.
Built for the moment the stakes change
A business sale. A practice transition. A major rollover. Concentrated equity. Inherited wealth. At that point, the question is no longer “what should I invest in?” It becomes: how much can I afford to lose, what has to be protected, what needs to keep compounding, and who’s actually managing the risk? Shell Capital exists for that moment.

The Market’s Leverage Trap: When Borrowed Confidence Becomes Forced Selling
Margin debt is easy to misuse. A record high doesn’t mean the market has to decline. Markets grow. Account values grow. A larger equity market can support more nominal debt than a

The Market Isn’t Just Expensive. It’s Dependent.
Valuation alone is the wrong frame. Not because it doesn’t matter. Because it doesn’t tell you what the market is depending on. Right now, the market is depending on earnings veloc
