The hard technology sector has remained the central market theme since the "September 24th" market surge began. However, looking back from the current vantage point, the return profiles of different indices, even those focused on leading tech companies, have varied significantly.

Over the measured period, the Sci-Tech Innovation and Entrepreneurship 50 Index has surged by 260%. In comparison, the Sci-Tech Innovation 50 Index gained 243.35%, while the ChiNext 50 Index advanced 209.86%.

While all three indices are associated with "hard tech," their internal sector compositions and risk-return characteristics are distinctly different, which has ultimately led to their notable divergence during this market phase.

Key Distinction: Sector Allocation, Not Stock Selection

The fundamental difference between the three indices lies in their sector weightings, which dictates their beta characteristics under varying market conditions.

The Sci-Tech Innovation 50 Index is essentially a "STAR Market Semiconductor Index." Based on Shenwan secondary industry classifications, the semiconductor sector dominates with a staggering weight of approximately 83%.

Its top ten constituents are exclusively semiconductor-related companies, including Cambricon Technologies Corp Ltd (SHA: 688256), Montage Technology Co Ltd (SHA: 688008), Advanced Micro-Fabrication Equipment Inc China (SHA: 688012), Hygon Information Technology Co Ltd (SHA: 688041), and Semiconductor Manufacturing International Corporation (SHA: 688981), collectively accounting for over 60% of the index weight.

This structure means investing in the Sci-Tech Innovation 50 is essentially a bet on the semiconductor cycle. It offers explosive upside during industry upswings but is equally susceptible to sharp drawdowns during periods of inventory correction or policy uncertainty.

The ChiNext 50 Index features a dual-core structure of "Communications + New Energy," with communications at around 34%, batteries at 20%, and a smaller semiconductor allocation of about 8.27%.

More critically, its weight is highly concentrated in a few stocks. The combined weight of just two constituents, Innolight Technology Co Ltd (SHE: 300308) and Contemporary Amperex Technology Co Ltd (SHE: 300750), exceeds 33%, while the top three holdings account for over 45%.

This concentration performed exceptionally well when the optical module and new energy sectors rallied simultaneously. However, excessive single-stock weights also mean the entire index can be dragged down if a major holding corrects due to earnings or valuation concerns.

The differentiating advantage of the Sci-Tech Innovation and Entrepreneurship 50 Index lies in its "balanced cross-board allocation," with semiconductors at approximately 45.7%, communication equipment at 21.7%, and batteries at 10.4%, among others.

It retains the semiconductor-driven growth potential of the STAR Market while incorporating leading optical module and new energy companies from the ChiNext board. Furthermore, through dual-cap mechanisms—limiting single-stock weight to 10% and single-sector exposure to 80%—it avoids excessive concentration in individual stocks or sectors.

Reasons for the Dual Innovation 50's Outperformance

The answer lies in the rhythm and structure of this hard tech market cycle.

Since the "September 24th" surge in 2024, the hard tech rally has not been a one-way street but has experienced multiple rounds of style rotation and sector leadership changes.

Themes like CPO/fiber optics, PCB, semiconductor chips, AI computing power, and new energy have taken turns leading the charge. One quarter might see a surge in STAR Market semiconductor equipment stocks, while the next quarter could witness optical modules and battery stocks from the ChiNext board taking over as leaders.

In this rotational environment, indices with overly high exposure to a single sector are prone to a mismatch where the index rises but investors' portfolios don't capture the gains effectively.

The Sci-Tech Innovation 50 performs strongest when semiconductors lead, but it can lag when capital rotates into optical modules or new energy.

The ChiNext 50 faces a similar issue. When Contemporary Amperex Technology Co Ltd corrects due to intensifying industry competition, the index's overall performance can be weighed down even if the optical module sector is rising.

By allocating across sectors from different boards, the Sci-Tech Innovation and Entrepreneurship 50 Index achieves a smoother return trajectory. It keeps pace when STAR Market semiconductors rally and doesn't miss out when ChiNext's new energy and optical module sectors gain momentum. This "diversified exposure" structure ultimately translates into higher cumulative returns during rotational markets.

Regarding current valuations, all three indices have reached historically elevated levels following the significant rally.

The Sci-Tech Innovation and Entrepreneurship 50 Index has a TTM P/E of 73.45, with 3-year and 5-year percentile ranks of 98.2% and 95.6%, respectively. Its P/B ratio is 9.30, with near 3-year, 5-year, and 10-year percentiles of 98.21%, 89.6%, and 87.9%.

This indicates that the market has already priced in a relatively optimistic outlook for the hard tech sector. Future returns will likely depend more on the realization of corporate earnings rather than further valuation expansion.

In summary, the Sci-Tech Innovation 50 acts as a "Semiconductor Beta Amplifier," the ChiNext 50 is a "Communications + New Energy Dual-Leader Index," while the Sci-Tech Innovation and Entrepreneurship 50 serves as a cross-board "Hard Tech Broad-Based Index."

Each has its own positioning, with no absolute superiority. The outperformance of the Dual Innovation 50 in this cycle is fundamentally because its sector allocation structure better matched the multi-sector rotational rhythm of the current market. It exchanged systematic diversification for a more favorable long-term risk-return profile.
