Why the same market produces different results for different strategies

Investors often perceive the market as a single environment with identical conditions for all participants. In reality, the same market can generate profits for some strategies and losses for others — at the very same time.

This is neither a paradox nor a coincidence. The difference in outcomes is explained by how each strategy interacts with the current market regime. Understanding this logic is a key element of professional capital management.

The market is not homogeneous

Financial markets are constantly changing. They pass through different phases, varying in movement structure, volatility levels, and liquidity.

Even if an asset’s price appears to move “in one direction,” the underlying market dynamics can be fundamentally different. It is these dynamics that determine which strategies have a statistical edge at any given moment.

In essence, the market is not a single state but a set of alternating regimes.

The concept of market regimes

A market regime is a set of characteristics that describes the market’s current behavior. Key parameters include:

• Direction of movement (trending or non-trending);
• Level and structure of volatility;
• Stability or fragmentation of liquidity;
• Speed and nature of price impulses.

Changes in these parameters directly affect the performance of trading strategies.

Why strategies react differently to the market

Each strategy is designed for a specific type of market behavior. It profits not “from the market as a whole” but from particular conditions.

For example:

Momentum and trend-following strategies

• Earn profits during directional movements and periods of rising volatility.
• Lose efficiency in sideways markets or during frequent false impulses.

Mean reversion strategies

• Perform well in range-bound markets with stable liquidity.
• Can incur losses during strong trends.

Arbitrage and low-volatility strategies

• Work best when price relationships are predictable and spreads are stable.
• Their advantage may temporarily disappear in stressed market phases.

Thus, the same market simultaneously creates opportunities and risks — depending on the strategy’s logic.

The role of volatility as a key factor

Volatility is one of the main “switches” of market regimes.

For some strategies, increased volatility means:

• Expanded movement ranges,
• Strong impulses,
• Higher potential returns.

For others, it represents instability, higher costs, and loss of predictability.

Therefore, identical price movements under different volatility structures can produce opposite outcomes for different systems.

Why you cannot judge a strategy outside its market context

A common investment mistake is evaluating a strategy without considering the market environment in which it operated.

Statements like:

• “This strategy has stopped working,”
• “It used to make money, now it doesn’t,”

often indicate not a model failure but a shift in the market regime, where its statistical edge is temporarily not realized.

Professional evaluation always requires answering: in which conditions should the strategy work — and in which should it not?

How funds adapt to regime changes

In institutional capital management, the key task is not to find a “universal” strategy but to build a system resilient to changing market phases.

This is achieved through:

• Combining strategies with different logic;
• Using trading filters;
• Reducing activity in unfavorable regimes;
• Strict risk management.

This approach helps smooth the impact of regime changes on the overall portfolio result.

IQ Security Fund’s approach to market regimes

At IQ Security Fund, strategies are initially designed with the market’s changing nature in mind.

Our algorithms focus on:

• Identifying volatility and impulse phases;
• Adapting activity to current conditions;
• Limiting risk when the market does not reward the chosen type of strategy.

We do not expect a single model to perform equally well at all times.

Our goal is systemic resilience over the long term, rather than maximizing results in one specific regime.

The same market does not have to deliver the same outcome for all strategies.
Returns are formed at the intersection of a strategy’s logic and the current market regime.

Understanding this relationship allows investors to:

• Correctly evaluate performance;
• Avoid false expectations;
• Make more informed investment decisions.

This systematic, regime-oriented approach forms the core philosophy of IQ Security Fund.
