The filter separates risks the manager deliberately chose from risks that merely accumulated inside the portfolio. First, the manager defines the desired source of alpha—such as company-specific stock selection. Portfolio reports then decompose exposure by sector, geography, company size, factors, position weights, and dispersion. Every meaningful risk contribution is traced back to an explicit investment thesis. Exposure supported by that thesis is intentional and may remain even when it increases volatility. Exposure with no deliberate rationale is unintended and should be reduced, hedged, or offset. The result is not a low-risk portfolio; it is a portfolio whose risks are understood and aligned with the manager’s actual edge.
Origin
Extracted from Masters in Business, where Jeffrey Becker explained how Jennison distinguishes deliberate concentration from unintended portfolio risk.
Core principles
- 01Every material risk should have an explicit investment rationale
- 02Stock selection should drive active returns
- 03Concentration and unmanaged exposure are different things
- 04Factor, sector, size, and geographic risks require separate inspection
- 05Risk reports should reveal rather than dictate investment decisions
How to run it
- 1
Define the intended edge
Specify the investment capability that should produce excess returns, such as fundamental stock selection.
Pro tip Express the edge in one sentence before reviewing any risk report.
Watch out An undefined edge makes every exposure appear acceptable after the fact.
- 2
Decompose the portfolio
Measure exposures by stock, sector, geography, size, style factor, and other relevant dimensions.
Pro tip Review both absolute exposure and contribution to active risk.
Watch out Position counts alone do not reveal correlated exposures.
- 3
Trace each major risk
Connect every significant risk contribution to a documented security-level thesis.
Pro tip Ask whether the exposure would still exist if the individual stock ideas changed.
Watch out A portfolio can look stock-driven while actually expressing one hidden macro factor.
- 4
Classify the exposure
Label risks supported by the strategy as intended and those without a clear rationale as unintended.
Pro tip Require a positive explanation rather than accepting the absence of an objection.
Watch out Do not relabel an accidental exposure as intentional merely because it has performed well.
- 5
Correct accidental bets
Resize, replace, hedge, or offset holdings that create risk unrelated to the intended edge.
Pro tip Preserve the strongest stock theses while choosing the least disruptive correction.
Watch out Mechanical limits can damage the strategy if applied without understanding security-level conviction.
- 6
Monitor continuously
Repeat the decomposition as prices, correlations, and portfolio weights change.
Pro tip Schedule reviews and add event-driven checks after major market moves.
Watch out An intended risk can become unintended when the original thesis changes.
In the wild
A concentrated portfolio contains several individually compelling growth companies. Risk decomposition reveals that their combined contribution is dominated by a shared large-cap factor rather than distinct stock theses. The manager retains the highest-conviction names but adjusts weaker positions to restore stock-specific risk.
→ The portfolio remains concentrated while its active risk more closely reflects fundamental security selection.
Common mistakes
Treating volatility as unintended risk
A concentrated strategy can be deliberately volatile; the question is whether that volatility arises from chosen theses.
Checking sectors only
Size, geography, style factors, correlations, and supply-chain exposures can create equally important accidental bets.
Letting reports replace judgment
Risk analytics identify exposure, but the manager must decide whether it is justified by the investment process.
Is it for you?
Best for
It is best for active managers who intentionally accept stock-specific risk but want clarity about all other exposures.
Not ideal for
It is not designed to eliminate volatility or turn a concentrated strategy into an index-like portfolio.
From the transcript
“From a risk perspective, what we want to protect against is unintended risk.”
“So we're taking very deliberate and concentrated risk.”
“We want to make sure at the at the end of the day that the risk we're taking is is stock specific.”
