Congratulations to our colleagues on their well-deserved promotions and new hires welcomed this year. We are also excited to add further breadth to the Research team with active searches for Associate roles included below.
Mid Cap companies continue to offer a compelling blend of stability and growth, despite the Russell Mid Cap Growth Index increasingly drifting from its traditional definition. Rising concentration, a shrinking number of constituents, and sharp sector shifts driven by mechanical rebalancing have made passive exposure less representative of the true Mid Cap landscape. An active, research-driven approach can help restore alignment with the segment’s fundamentals. By emphasizing differentiated, scalable businesses with strong management teams, pricing power, and disciplined capital allocation, active managers can identify opportunities that index-driven strategies often overlook— particularly as companies evolve, strengthen their competitive positions, or graduate from the small-cap universe. As the Mid Cap index continues to evolve, we at TimesSquare remain committed to offering clients a reliable, research-driven path to capturing the long-term potential of this vital segment of the market.
This quarter, we focus our perspective on the Information Technology sector and the drivers behind why it remains fundamentally robust and how the dynamics of value creation are changing.

“We believe the Mid Cap Strategy is well positioned for the next cycle, one likely to be defined by dispersion, separating companies that merely participate in the AI build from those successfully monetizing AI deployment.”
The market is pivoting from rewarding speculative growth to demanding profitable scaling and tangible return on investment (ROI) from massive infrastructure investments. We believe the next cycle will be defined by dispersion, separating companies that merely participate in the AI build from those that successfully monetize the AI delivery. Below is a breakdown of the key factors influencing the sector's trajectory.
As long-time U.S. public equity investors we view mid capitalization companies as an attractive balance between large caps and small caps. These companies have matured into a growth phase that is often more stable than when they were small caps, though with higher incremental growth than large caps. The return and risk data over the last 25 years bears that out:

In addition, when reviewing five-year monthly rolling performance over that same 25-year period:
By FTSE Russell’s definition, the widely used Russell Midcap Index always begins with 800 stocks and allows for proportionate weighting of those names into the Growth⁴ and Value⁵ indexes. Typically, both Growth and Value have over 400 names each. However, with the more recent trend of market cap expansion / capital moving into Growth stocks, the dynamics for the Russell Midcap Growth, Value, and overall Index have changed.
Because FTSE Russell balances the capital between growth and value, fewer names are needed to populate the Growth Index. As the Russell Midcap Growth Index has become more top heavy, it now includes fewer stocks than ever. The index has fewer than 300 companies (281 to be exact) for the first time on record, down from a high of 552 in 2015 and 408 just three years ago. Furthermore, this has resulted in greater concentration and total weight in the Russell Midcap Growth’s top ten. Ten years ago, the top ten weight was under 10%, 15% in 2024, and now 21.5% as of September 2025.

While FTSE Russell reconstitutes its indexes annually (and beginning in 2026, semiannually), in part to “graduate” the larger cap constituents to Russell’s mega cap Top 200 Index⁶, there has been a steady upward trend of the size profile for the Russell Midcap Growth Index:

The same mechanistic nature of the index creation and rebalancing that causes those concentration levels also affects the economic sector exposures within the index. Shifts in the index during a rebalance can be dramatic and do not necessarily reflect economic realities or investment opportunities. Take the most recent rebalance in June 2025. Over 1,000 basis points abandoned the Information Technology sector and more than 800 basis points flooded into Consumer Discretionary. It’s not as if the economic landscape or opportunity set changed, but the structure of the index became dramatically different. Russell intends to reconstitute the indexes twice per year beginning in 2026 (once in June and again in November). In our view, this should mitigate some of the magnitude of these significant shifts, but it likely is not the trend.
In summary, the Russell Midcap Growth Index is increasingly concentrated, leading to material shifts in economic exposure, and appears to be drifting away from the historical market cap definition of Mid Cap. This steady increase in size and concentration is likely to continue unabated, which fundamentally changes the essence of Mid Cap when only using the indexes. As a small to mid-cap manager for over 25 years, we believe in offering our clients the exposures they are seeking, and style purity is paramount to maintaining the integrity of our strategy.
Being an active manager focused on quality growth businesses, we strive to avoid the hype that attracts capital over short time periods to the biggest index holdings, momentum darlings, or hyper growth names. Passive strategies will blindly mirror these trends. The bigger a name or sector gets in the index, the more capital chases which results in managers benchmark hugging / closet indexing. In contrast, TimesSquare’s fundamental research process involves a thorough bottom-up analysis of companies and how they create economic growth.
Our portfolios are not constructed top down by sector or industry. We take a clean slate approach to building positions and evaluating/revaluating the companies based solely on their merits. We favor differentiated, scaling businesses that are gaining share, demonstrating pricing power, and most importantly, deploying investor capital with a focus on generating returns. Our strategy primarily focuses on secular growth and long-term trends, while some are more cyclically positioned. Overall, we believe our 25-year track record demonstrates a consistent quality bias that endures through varying economic cycles. Since inception, our team has remained disciplined in executing this strategy and pursuing quality growth businesses, as illustrated in the market environment analysis below.

It’s worth reiterating that the way the benchmark is constructed, and growth and value are split, are based on definitions that haven’t changed in decades. As our team evaluates our holdings and seeks out new ideas, we have the freedom to cast a wider net across the landscape of companies, often finding those that don’t fit into the traditional growth or value boxes. These ideas are often overlooked by managers looking solely at the big index weights or the popular theme of the day.
One source of new ideas comes from a reexamination of companies undergoing potentially positive change(s) that the market is not fully appreciating (e.g. upgraded senior management, enhanced strategies/business models, improvements in their end markets). We believe we have the important advantage of sourcing ideas as they “graduate” from the dedicated Small Cap strategies we manage. These names are covered by the same investment team, so there is familiarity and institutional knowledge of these businesses when they have grown to the thresholds to be eligible for Mid Cap. When reviewing our Mid Cap Growth portfolio today, over 20% of current positions were previously held in our Small Cap strategy and are graduates of the selection process. Elevating these small cap names is one manner that refreshes our strategy and stays true to the essence of Mid Caps.
Passive investing in Russell Midcap index strategies increasingly means losing access to the true breadth and depth of companies across the Mid Cap market capitalization range. We argue that our active management and rigorous stock selection helps to provide a more authentic representation of Mid Cap exposure, allowing us to uncover attractive opportunities overlooked by the benchmark. As the index has become significantly larger and more concentrated, the need for this active approach is growing. Since these indexes are the default standard for Mid Cap allocations, their inherent structural risks are often disregarded; therefore, relying on the index alone for distinct Mid Cap exposure may prove insufficient. In other words, if you’re looking for exposure to the Mid Cap space and believe you’re getting it from allocating to the index, think again.
