Insurance sounds boring. You pay premiums, the insurance company pays claims. That’s it, right?
Wrong. There’s a hidden advantage baked into every insurance company’s business model. Insurance companies collect premiums upfront and don’t pay claims until later. That creates what’s called “the float”—billions in capital that sits waiting to be deployed.
The float is why insurance companies can be some of the market’s best long-term compounders. Warren Buffett built Berkshire Hathaway’s empire by aggressively investing the float in stocks and entire companies. Other insurance companies take a much more conservative approach, investing the float in bonds to generate steady income.
This creates a spectrum of risk and reward. Understanding where each insurance company sits on that spectrum is crucial before you invest.
The Buffett Model: Aggressive Equity Investing
Berkshire Hathaway pioneered the aggressive float deployment model. Warren Buffett didn’t just invest the float in stocks. He used it to buy entire companies. He invested in icons like Coca-Cola and American Express. Over decades, this approach turned an insurance company into a giant conglomerate.
Current CEO Greg Abel is following a similar playbook. Recently, he bought homebuilder Taylor Morrison with the plan to eventually integrate it with other housing-related businesses Berkshire owns. That’s aggressive float deployment.
Other companies have tried to follow this model, including Markel Group and more recently Brookfield Corporation and Howard Hughes. These are defined as investment-led insurance companies.
The advantage of this approach is obvious: if you’re investing the float in appreciating assets—stocks and whole companies—you can generate capital gains that compound over decades. Insurance operations might be break-even or barely profitable, but the float invested in growth assets creates shareholder value.
The disadvantage is equally obvious: if a major claim event hits during a bear market, you might be forced to sell equity holdings at a loss to cover claims. You’re taking investment risk to generate returns.
The Conservative Model: Bond-Heavy Portfolios
Most insurance companies are much less aggressive than Berkshire Hathaway. Progressive, for example, had equity investments of around 4.5% of its total portfolio at the end of Q1 2026. The vast majority of its float is invested in bonds.
Chubb takes a slightly more aggressive stance with around 16.5% equity exposure (including private equity), but it’s still well below aggressive deployers.
The rationale is sound: bonds provide reliable income that can support earnings. If a major claim event hits, you have dry powder in bonds you can liquidate without taking a loss. You’re prioritizing stability and claims-paying ability over capital gains.
The tradeoff is obvious: bonds don’t provide the capital gains opportunity that equities do. Over decades, a bond-heavy portfolio will underperform an equity-heavy one in the long term.
The Middle Ground: Selective Equity Exposure
Cincinnati Financial sits somewhere in the middle. The company allocates approximately 39% of its investment portfolio to equities. That’s significantly higher than Progressive or Chubb, but much lower than Berkshire Hathaway.
Cincinnati Financial doesn’t buy entire companies like Berkshire does. But it does take meaningful equity exposure to benefit from market returns. It’s a compromise between aggressive growth and conservative stability.
The company is also a Dividend King, with over 50 years of consecutive annual dividend increases. That’s a signal of financial stability and management confidence.
Cincinnati Financial offers investors exposure to the float compounding power without the extreme risk of buying entire companies with insurance premiums.
Understanding Your Risk Tolerance
The key insight is this: you’re not just buying an insurance company. You’re buying a specific approach to deploying the float. That has huge implications for your long-term returns and risk profile.
Berkshire Hathaway offers the highest upside potential because it aggressively invests the float in growth assets. But it also carries the highest risk. A prolonged bear market combined with a major claim event could force the company to liquidate equity positions at losses.
Progressive and Chubb offer lower risk because they’re primarily invested in bonds. But they also offer lower long-term return potential because bonds don’t compound the way equities do over decades.
Cincinnati Financial offers middle-ground positioning: meaningful equity exposure for growth, but not so much that claims could force fire-sales during downturns. The long dividend history suggests management is confident in this approach.
The Secret Sauce
What makes insurance stocks powerful long-term compounders isn’t the insurance business itself. Insurance is often a break-even or low-margin business. What makes them powerful is the float.
Float transforms insurance from a boring, slow-growth business into a compounding machine. The company collects premiums today but doesn’t pay claims for months or years. During that time, it invests the float. That investment return—whether from equity gains or bond interest—compounds over decades.
When you invest in an insurance company, you’re not just buying their insurance operations. You’re buying billions in capital (the float) that will be deployed into assets. How aggressively that capital is deployed determines your long-term returns.
Choosing Your Insurance Investment
The choice depends on your risk tolerance and time horizon.
Want maximum long-term upside and can tolerate bear market drawdowns? Berkshire Hathaway and the aggressive float deployers offer that.
Want stability and regular income, even if it means lower capital gains? Progressive and Chubb offer that.
Want a balanced approach? Cincinnati Financial offers meaningful equity exposure with the stability of a Dividend King.
Don’t just buy an insurance company because it’s cheap or yields well. Buy one because you understand how it deploys the float and that approach matches your investment goals.
The float is the secret sauce that transforms boring insurance into powerful compounding. Understanding how each company uses it is how you find the best insurance stocks for your portfolio.
