This method controls investment risk through three complementary layers. Diversification limits the damage from any one company, industry, or thesis. Position sizing then aligns the capital at risk with uncertainty, downside magnitude, liquidity, and conviction. Finally, the financial characteristics of the company provide security-level protection: reasonable valuation, free cash flow, manageable debt, and shareholder-friendly capital allocation can reduce the severity of adverse outcomes. A manager may still hold concentrated positions, but only when these characteristics make the perceived risk lower. When new evidence appears—such as declining users at a technology company—the manager can trim the position even if the long-term thesis remains plausible. Risk control is therefore continuous rather than a one-time purchase decision.
Origin
Extracted from Masters in Business, where Leon Cooperman explained how he responded to uncertainty in Facebook and protected concentrated value positions.
Core principles
- 01No single risk control is sufficient.
- 02Diversification limits dependence on one thesis.
- 03Position size should reflect uncertainty and downside.
- 04Strong financial characteristics can provide intrinsic protection.
- 05Concentrate only where perceived risk is lower, not merely where upside is exciting.
How to run it
- 1
Map Concentration
List position, sector, factor, and thematic exposures across the portfolio. Identify holdings that may fail for the same underlying reason.
Pro tip Measure hidden correlation among companies that appear to operate in different industries.
Watch out A portfolio with many tickers can still be economically concentrated.
- 2
Set Position Limits
Size each holding according to downside, liquidity, evidence quality, and thesis confidence. Define the conditions that require a reduction.
Pro tip Use smaller initial positions when technological or regulatory uncertainty is high.
Watch out High conviction does not eliminate the possibility of being wrong.
- 3
Inspect Financial Protection
Review valuation, leverage, free cash flow, liquidity, and capital allocation. Prefer companies capable of surviving adverse conditions without relying on external financing.
Pro tip Look for several protections, such as a low multiple plus strong free cash flow and disciplined buybacks.
Watch out A low multiple is not protective when the underlying cash flow is collapsing.
- 4
Respond to New Evidence
When fundamentals or uncertainty change, reassess expected value and position size. Trim exposure when risk rises even if the thesis has not conclusively failed.
Pro tip Distinguish a risk-management trim from a full thesis rejection.
Watch out Waiting for certainty can turn a manageable loss into a major one.
- 5
Concentrate Selectively
Allow larger positions only where downside is bounded by valuation and financial quality. Keep speculative or binary investments smaller.
Pro tip Concentrate in lower-risk opportunities rather than simply the most exciting stories.
Watch out Perceived safety can be wrong, so continue monitoring concentrated holdings.
In the wild
After Facebook reported disappointing results and declining users, Cooperman reduced the position. He still believed the company could have substantial future growth, but treated the new information as evidence that technology risk might be changing.
→ The trim reduced portfolio exposure without requiring an immediate conclusion that the entire long-term thesis was broken.
Cooperman cited low market multiples, substantial free cash flow, and large share repurchases as protective characteristics. Those features made him more comfortable taking concentrated positions than he would be in expensive companies without financial support.
→ Concentration was directed toward securities perceived to have stronger downside protection.
Common mistakes
Counting Tickers as Diversification
Holdings can share the same economic driver even when their business descriptions differ. Examine correlated risks rather than the number of positions.
Sizing Only for Upside
A large potential gain does not justify a large position when the outcome is binary or liquidity is poor. Size from downside first.
Treating Quality as Price-Independent
Financially strong companies can still carry substantial risk at extreme valuations. Include price in the protection analysis.
Is it for you?
Best for
It is best for active equity investors who want to hold meaningful positions while maintaining explicit downside controls.
Not ideal for
It is not ideal as a complete substitute for liquidity planning, hedging, or operational risk management.
From the transcript
“So you control risk by diversification, You control risk by position size, You control risk by the financial characteristics of the company you own.”
“You have an element of protection, and that's where I feel most comfortable.”
“So I'd have concentrated bets, but in things that I perceived to be less risk here.”
