Investors seeking actively managed U.S. equity exposure increasingly weigh style-based and theme-based strategies as alternatives to plain market-cap indexing. The iShares U.S. Equity Factor Rotation Active ETF (DYNF) and the iShares U.S. Thematic Rotation Active ETF (THRO) illustrate two distinct approaches to that goal. While both are BlackRock active ETFs benchmarked against broad U.S. indices, they do not compete directly on methodology: DYNF tilts exposure among rewarded style factors, whereas THRO shifts among structural and cyclical themes. Comparing them clarifies how cost, sector concentration, and volatility can diverge even within the same issuer's active lineup.
DYNF seeks to outperform the U.S. equity market by dynamically allocating across historically rewarded style factors—including value, quality, momentum, size, growth, and minimum volatility—through a proprietary factor-rotation model. The fund is benchmarked against the MSCI USA Index and launched in March 2019, giving it a longer live track record than THRO. Its portfolio holds roughly 200 securities spanning large- and mid-capitalization U.S. stocks. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Top holdings have recently included NVDA, AAPL, MSFT, AMZN, JPM, META, CSCO, GOOGL, AVGO, and Berkshire Hathaway. Information technology is the largest sector weight at roughly 39%, followed by financials and communication services, with more modest exposure across health care, industrials, consumer discretionary, and energy. The fund carries an expense ratio of 0.26% and, as a diversified factor strategy, tends to exhibit beta and volatility close to the broad market.
THRO seeks long-term capital appreciation through dynamic exposure to evolving U.S. market themes, using a data-driven and artificial-intelligence-powered process to rotate among structural and cyclical trends. Launched in December 2021, it is benchmarked against the S&P 500 Index and is structured as a non-diversified fund, meaning it may concentrate holdings in fewer issuers than a diversified mandate. From what I see, its higher concentration adds a distinct risk profile worth monitoring.
The fund holds approximately 250 securities, with a heavier technology bias than DYNF—recently around 40–45% of assets. Top holdings have included AAPL, NVDA, MSFT, AMZN, GOOGL, MU, JPM, XOM, CAT, and WMT. Its expense ratio of 0.57% is more than double DYNF's, and its three-year standard deviation and beta have trended modestly higher, consistent with its more concentrated, growth-oriented thematic positioning.
Both funds are heavily influenced by the performance of large-cap technology and growth-oriented companies, which have driven much of the U.S. market's returns in recent market cycles. Developments in artificial intelligence, semiconductor demand, and cloud computing have concentrated capital flows into mega-cap names, supporting both portfolios but tilting performance toward THRO's more tech-heavy book. At the same time, investors' sensitivity to valuation and interest-rate expectations has encouraged periodic rotation into value, quality, and defensive factors—an environment that can favor DYNF's factor model. Concentration risk, earnings-cycle shifts in the largest technology holdings, and the influence of a narrow group of mega-cap stocks remain key considerations for both funds.
In recent weeks and months, both ETFs have tracked the broad upward trend in U.S. large-cap equities, with relative positioning shaped largely by sector composition. THRO's larger technology allocation has made it more responsive to strength in semiconductors and megacap growth, while DYNF's broader sector mix and factor tilts have provided somewhat more balanced participation across financials, industrials, and energy. On a risk-adjusted basis, DYNF has historically exhibited lower volatility and a beta closer to the market, whereas THRO's non-diversified, thematic structure has introduced incrementally higher volatility and concentration. For investors comparing these funds, the trade-off is essentially between a lower-cost, more diversified factor engine and a higher-cost, more concentrated thematic strategy.
I often turn to Tickeron’s AI Screener when comparing ETFs like these. It is an AI-powered stock and ETF discovery tool that helps traders and investors filter the market based on technical patterns, fundamentals, trends, volatility, and AI-driven signals. Users can scan thousands of securities using customizable filters such as industry, market capitalization, technical indicators, price patterns, and performance metrics, helping to surface trade ideas, trending stocks, and breakout candidates more efficiently than manual screening. I find it especially useful for quickly highlighting differences in sector exposure and risk metrics between funds like DYNF and THRO.
Based on observable structural factors, Tickeron's AI framework would currently lean toward DYNF over THRO. The case rests on DYNF's materially lower expense ratio (0.26% versus 0.57%), its broader diversification across sectors and style factors, its lower historical volatility and beta, and its longer live track record. While THRO offers a more concentrated, potentially higher-growth thematic tilt, that positioning carries greater sector risk and higher cost. On a probabilistic basis weighing cost efficiency, diversification, and risk-adjusted consistency, the AI-driven assessment favors DYNF as the more durable choice in the current environment.
