Distinguishing Types of Drawdowns Is More Important Than Blindly Buying the Dip

Resumen

Distinguishing between types of drawdowns is more important than blindly buying the dip. Academic finance categorizes risk into systemic (market-wide, unavoidable) and idiosyncratic (company-specific). Similarly, drawdowns can be market-driven (systemic, like the 2008 crisis) or company-specific (idiosyncratic, like the recent AI-driven selloff in software stocks). Using FactSet (FDS) as an example, the article illustrates that a systemic drawdown, such as in 2008/09, was a test of the market's durability, not FactSet's economic moat. In these cases, investors can leverage a behavioral advantage—patience and a long-term view—as history shows markets tend to recover. Conversely, the current 2025/26 drawdown in software stocks is largely idiosyncratic, driven by specific fears that AI could disrupt industry pricing power and erode moats. To capitalize on such a drawdown, an investor needs an analytical advantage: a more accurate vision of the company's future a decade from now than the market's pessimistic price implies. This requires understanding why informed sellers are wrong, a fine line between conviction and arrogance. The key takeaway is not to apply a blunt behavioral solution (like simply buying the dip) to a problem that requires nuanced, fundamental analysis.

Guide: Academic finance theory categorizes risk into systematic risk and idiosyncratic risk. Similarly, stock drawdowns can also be divided into two types: market-driven systematic drawdowns (such as the 2008 financial crisis) and company-specific idiosyncratic drawdowns (such as the current software stock crash driven by AI concerns).

Using FactSet as an example, Todd Wenning points out: during a systematic drawdown, you can leverage a behavioral advantage (patiently waiting for the market to recover); but during an idiosyncratic drawdown, you need an analytical advantage—having a more accurate vision of what the company will look like in ten years than the market does.

Amid the current AI impact on software stocks, investors must distinguish: is this a temporary market panic, or is the moat truly crumbling?

Academic finance theory posits two types of risk: systematic and idiosyncratic.

Systematic risk is unavoidable market risk. It cannot be eliminated through diversification, and it is the only type of risk for which you are compensated.
On the other hand, idiosyncratic risk is company-specific risk. Because you can cheaply purchase a diversified portfolio of uncorrelated businesses, you are not compensated for taking on this risk.

We can debate Modern Portfolio Theory another day, but the systematic-idiosyncratic framework is helpful for understanding different types of drawdowns (the percentage decline from peak to trough of an investment) and how we, as investors, should evaluate opportunities.

From the moment we picked up our first value investing book, we were taught to take advantage of a despondent Mr. Market when stocks are sold off. If we remain calm while he loses his senses, we will prove ourselves to be stoic value investors.

But not all drawdowns are the same. Some are market-driven (systematic), while others are company-specific (idiosyncratic). Before you make a move, you need to know which type you're looking at.

The recent sell-off in software stocks due to AI concerns illustrates this point. Let's look at the 20-year history of drawdowns between FactSet (FDS, blue) and the S&P 500 (measured via the SPY ETF, orange).

Source: Koyfin, as of February 12, 2026

FactSet's drawdown during the financial crisis was primarily systematic. In 2008/09, the entire market was worried about the durability of the financial system, and FactSet could not be immune to these concerns, especially since it sells products to financial professionals.

At that time, the stock's drawdown had less to do with FactSet's economic moat and more about whether FactSet's moat would matter if the financial system collapsed.

The 2025/26 FactSet drawdown is the opposite case. Here, the concerns are almost entirely focused on FactSet's moat and growth runway, alongside broader fears about accelerating AI capabilities disrupting pricing power in the software industry.

In a systematic drawdown, you can more reasonably make a time arbitrage bet. History shows that markets tend to rebound, and companies with intact moats may emerge even stronger than before, so if you are willing and able to remain patient while others panic, you can leverage a strong stomach to exploit a behavioral advantage.

However, in an idiosyncratic drawdown, the market is telling you that something is wrong with the business itself. Specifically, it suggests increasing uncertainty about the business's terminal value.

Therefore, if you hope to take advantage of an idiosyncratic drawdown, you need to possess an analytical advantage in addition to a behavioral one.

To succeed, you need to have a more accurate vision of what the company will look like in ten years than the current market price implies.

Even if you know a company well, this is not easy to do. Stocks don't typically fall 50% relative to the market for no reason. A lot of once-steadfast holders—even investors you might respect for their deep research—had to capitulate for this to happen.

If you are going to step in as a buyer during an idiosyncratic drawdown, you need to have an answer for why these otherwise informed and thoughtful investors were wrong to sell and why your vision is correct.

There's a fine line between conviction and arrogance.

Whether you are holding a stock in a drawdown or looking to initiate a new position in one, it's important that you understand what type of bet you are making.

Idiosyncratic drawdowns can tempt value investors to start looking for opportunities. Before you take the plunge, make sure you aren't using a blunt behavioral solution to solve a problem that requires nuanced analysis.

Stay patient, stay focused.

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

Daily 7.2 Trillion KRW: Foreign Capital's Record Net Buying on Friday! Wall Street Says Headwinds for Korean Stock Fund Flows Have Subsided

South Korean stock market sees a dramatic shift in fund flows. On July 31, foreign investors made a record net purchase of approximately KRW 7.2 trillion in KOSPI stocks, marking a fundamental reversal from the persistent large-scale net outflows seen in previous months. This contributed to a significant narrowing of foreign net selling in July to KRW 9.8 trillion, down sharply from KRW 48.4 trillion in June and KRW 44.5 trillion in May. Simultaneously, domestic institutional pressure eased. South Korean pension funds and asset managers turned to a net buying position in July, purchasing KRW 1.0 trillion worth of KOSPI shares, contrasting with net sales in May and June. Market volatility is expected to be dampened by new financial regulations. Effective July 31, the Financial Services Commission tightened access for retail investors to single-stock leveraged ETFs by raising the minimum cash deposit requirement. Trading volumes for these products subsequently dropped to about 50% of their monthly average. Citigroup Research maintains its year-end KOSPI target of 10,000 points. The firm cites several supportive factors: the substantial easing of headwinds from capital outflows, a robust fundamental outlook for the semiconductor sector, historically low market valuations, strong economic fundamentals, and the potential for policy support from financial authorities if needed.

Breaking! OpenAI's Next-Gen AI Solves 10 Fields Medal-Level Problems

OpenAI's next-generation AI model Astra achieves breakthroughs in 10 long-standing mathematical conjectures. The results, including constructing the first known infinite, finitely presented non-sofic group—resolving a major question since 1999—and advancing the high-dimensional sphere packing problem beyond a 46-year-old barrier, are detailed in a 249-page paper. Key proofs have been formally verified using Lean 4. The AI also refuted a rigidity conjecture by Fields Medalist Alain Connes. According to OpenAI, generating these proofs cost under $2,000. Experts describe the findings as potentially Fields Medal-worthy and a landmark moment for both mathematics and AI, showcasing the model's ability to produce profound, human-like reasoning across diverse fields like group theory, geometry, and operator algebras.

How to Make Yourself Irreplaceable by AI Forever

This article argues that the primary threat from AI is not job replacement, but remaining trapped in "wage slavery"—financial dependence on employers. The path to becoming irreplaceable is not resisting AI, but becoming an "unemployable" individual who builds their own meaningful enterprise. The author identifies five key elements for this: Agency (acting without permission), Taste (judging what's worthwhile), Persuasion, Persistence, and Iteration. The solution is to stop being a "pawn" in someone else's game. To start, you must fundamentally change your identity and environment, then engage in rapid, real-world trial and error. While both coding and creating media (content) are powerful, content is more crucial. AI can generate assets, but true value lies in subjective, human-driven content that builds trust and narrative. The actionable advice is to carve out 15 minutes to answer foundational questions: 1) Uncover your "raw material"—what you know deeply or solve effortlessly. 2) Define your contrarian perspective—what common beliefs you think are wrong. The intersection of these answers is your direction. Finally, you must launch by publishing your first core idea immediately, using the feedback to iterate and develop the skills needed for a self-directed life and career.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.
