During the early session on March 5, hard tech stocks gained strength across the board. The "All-Chip" Sci-Tech Innovation Chip ETF (589190) opened higher and continued to rise, with its on-market price currently up over 3%. Following an unexpected earnings report that shook the market, Biwin Storage surged more than 16% today after hitting the 20% limit-up yesterday, aiming for a second consecutive trading day limit-up. Nexchip, VeriSilicon, and Dosilicon each rose more than 7%, while Topsec and others led the gains.
After reporting over four-fold profit growth for 2025, Biwin Storage recently released another stronger-than-expected earnings preview, confirming the memory "super cycle." The announcement showed that for January-February 2026, Biwin Storage achieved revenue between 4 billion and 4.5 billion yuan, a year-on-year increase of 340% to 395%. Net profit attributable to shareholders was between 1.5 billion and 1.8 billion yuan, representing a projected increase of 921.77% to 1086.13%.
Behind the soaring performance of memory leaders is the continuous sharp price increase of memory chips caused by a supply-demand imbalance. Recent news confirms that Samsung Electronics' first-quarter DRAM price increase has been finalized at over 100%, with the rate of increase expanding by approximately 30 percentage points within just one month.
Dongguan Securities stated that the rapid increase in demand for high-density memory from AI data centers, coupled with continuously rising memory chip prices, is driving profit growth for related companies. Semiconductor equipment and materials companies are benefiting from advanced process capacity expansion and supply chain localization efforts. With additional policy support, overall industry sentiment is expected to keep improving.
To position for the chip industry's "super cycle," high-beta 20% limit-up varieties are preferred. Public information shows that the Sci-Tech Innovation Chip ETF (589190) and its feeder fund passively track the SSE Sci-Tech Innovation Board Chip Index. This index includes 50 hard-tech constituents involved in semiconductor materials and equipment, chip design, chip manufacturing, and chip packaging and testing. While providing full-chain exposure to the chip industry, it has over 90% weight in core areas like integrated circuits and semiconductor equipment, indicating high hard-tech content and strong technical barriers.
Data shows that as of the end of 2025, the SSE Sci-Tech Innovation Board Chip Index had an annualized return of 17.93% since its base date, significantly outperforming peer indices such as the STAR Market and ChiNext Semiconductor Index, the China Securities Chip Index, and the CSI All Share Semiconductor Index, while also exhibiting a smaller maximum drawdown and a better risk-return profile.
