Traditional portfolios diversify across asset classes. WSC Model Portfolios diversify across investment strategies. Because each strategy has a structurally different return driver, the correlation between them stays low even when asset class correlations rise.
WSC ETF Model Portfolios: Quick Summary
Modern Portfolio Theory, introduced by Harry Markowitz in 1952, is built on a foundational assumption: combining assets with low or negative correlations reduces overall portfolio risk without sacrificing return. For decades, a portfolio of 60% equities and 40% bonds delivered exactly that. The negative correlation between stocks and bonds provided a natural hedge.
That assumption no longer holds reliably. Three structural changes have fundamentally altered the diversification landscape for traditional portfolios:
Globalization has increased the co-movement of asset classes across geographies and categories, particularly during periods of market stress when diversification is needed most. The correlations that underpinned traditional portfolio construction have increased structurally.
The negative stock-bond correlation that made balanced portfolios work for 40 years was a product of a specific macroeconomic environment: falling inflation and falling rates. In an inflationary environment, bonds and equities can fall simultaneously, eliminating the hedge.
Market cap-weighted equity indices are increasingly concentrated in a small number of stocks. Owning an S&P 500 ETF does not provide the breadth of diversification it did 20 years ago. Concentration has increased, not decreased, despite more companies being listed.
Traditional portfolio construction assumes correlations are stable over time. They are not. During periods of market stress, correlations between asset classes tend to converge toward 1, precisely when diversification is most critical. A portfolio optimized for normal conditions fails in tail scenarios.
The WSC ETF Model Portfolios are built on a different principle: instead of combining asset classes with the hope of maintaining low correlations, the portfolios combine investment strategies that are structurally non-correlated by design.
Each of the four underlying strategies has a distinct investment objective, a different return driver and a different market environment where it excels. Because the return drivers are structurally independent, the correlation between the strategies remains low even when asset class correlations rise.
The result is a portfolio framework that is designed to deliver positive returns across all four primary market environments: growth, recession, inflation and deflation. Not by predicting which environment will occur, but by ensuring that at least one strategy performs well in each.
The WSC Model Portfolio Composite is the equal-weighted combination of all four underlying strategies, rebalanced annually. Its performance record is live and publicly documented, updated weekly in the members area.

The Composite is built from four distinct ETF Model Portfolios, each designed to excel in a specific market environment. Because each portfolio uses a structurally different return driver, their correlation to one another remains low across market regimes.
The All Weather Portfolio is designed to deliver absolute positive and stable returns over a three-year investment horizon by systematically exploiting the diversification premium across asset classes. It is the most conservative of the four strategies and performs reliably across all four major economic environments: growth, recession, inflation and deflation.
The strategy applies the Maximum Diversification principle, which maximizes the ratio of weighted average asset volatility to overall portfolio volatility. This ensures that the portfolio utilizes the full available diversification benefit at all times, not just when correlations are low.
The Dynamic Variance Portfolio targets high absolute returns in strong up-trending global markets while systematically capping losses during volatile or declining market environments. It exploits time-series momentum in a systematic and rule-based way, adjusting exposure based on the strength and direction of prevailing market trends.
The strategy is designed for investors seeking equity-like upside participation with a disciplined mechanism for drawdown control. Its performance profile is most distinctive in strong trending environments where momentum strategies have historically added significant alpha.
The Sector Rotation Strategy selects the strongest trending sectors within the S&P 500 using a combination of time-series momentum and cross-sectional momentum. It is designed to limit downside potential during bear markets while participating fully in bull market advances.
By concentrating exposure in the strongest sectors at any given time, the strategy captures the best-performing segments of the equity market while systematically reducing exposure to weak or declining sectors. The aim is to deliver equity-like returns with meaningfully lower volatility over a full market cycle.
Importantly, this approach is independent of the WSC Market Regime Framework. It represents a distinct, price-driven allocation model and therefore adds an additional layer of diversification within the broader WSC research architecture.
The Inflation Proof Retirement Portfolio is specifically designed for conservative investors at or near retirement who require protection against inflationary market environments. It is designed to generate stable returns above the average inflation rate while minimizing losses when inflation expectations remain low.
The portfolio systematically allocates to inflation-sensitive assets using a diversification-based construction technique that ensures the broadest possible spread of inflation risk premia. It provides the most effective hedge within the Composite during high inflation periods, balancing the equity-heavy exposure of other strategies.

View Plans and PricingThe WSC Model Portfolio Composite invests 25% in each of the four strategies on an equal-weighted basis, rebalanced annually. Because each strategy has a different return driver and a different performance profile across market regimes, the correlation between the strategies remains structurally low.
The result is a portfolio that does not rely on any single return driver, does not assume stable asset class correlations and does not depend on a specific macroeconomic environment to perform. It is designed to generate outstanding risk-adjusted returns across all market regimes.

View Plans and PricingThe WSC ETF Model Portfolios are not built on intuition or market views. They are grounded in quantitative research, independently reviewed and recognized by the investment research community.
