UBS: A-Share Tech Stock Crowding Far from Historical Peak
N.R. Finch
UBS's latest report shows mutual-fund overweight in A-share mega-tech sits at 9.9%, well below the 14.1% record set in late 2015. With the current growth-style run lasting under two years, the market may be overstating crowding risk.
Turnover is sky-high — so why isn't it crowded?
Mega-tech's weekly turnover share hit 45.5% of all A-shares, while the sector's market-cap share is only 28.6%. Trading heat is undeniably at historical highs.
But UBS argues the mutual-fund overweight ratio is the real gauge of institutional crowding. This means → retail frenzy and institutional herding are two different things, and should not be conflated.
The current 9.9% overweight is below Q3 2025's 11.6%, and far below the consumer sector's all-time high of 18.7%. In plain terms = institutional chips are nowhere near piled into one trade.
How long does a style cycle usually last?
UBS reviewed five major style rotations since 2014 and found each typically runs about three years from formation to switch.
Two forces drive the clock: ① no single sector sustains peak-cycle fundamentals beyond three years; ② once fund positioning concentrates enough, shrinking alpha triggers redemptions, which feed back into prices and reverse the trend.
The current tech-growth style began with the September 2024 policy pivot — under two years ago. This means → by historical pattern, the rotation window has not yet opened.
Are any sub-sectors already getting crowded?
Electronics overweight has reached 6.6%, breaking above the prior high of 5.4% set in Q3 2020.
Telecom overweight has hit a new post-2010 high for three consecutive quarters, now at 4.0%.
This reflects uneven capital distribution within mega-tech — electronics and telecom are approaching crowded territory first. UBS says it will keep tracking these two sectors to see whether local risk spreads to the broader trade.
Can earnings support the rally?
UBS forecasts full-year 2026 A-share earnings growth rising from 3.9% in 2025 to 11%. Q1 non-financial A-share profit growth jumped from 0.8% to 11.8%.
STAR Market Q1 earnings surged 204.7% year-on-year; ChiNext reached 22.7% — both dwarfing the main board's 5.5%. This means → tech-growth sectors carry far greater earnings leverage than traditional sectors, giving the rally fundamental backing.
Gross and net margins rose 0.6 and 0.3 percentage points year-on-year, both the highest since 2023. In the first four months of 2026, profits in computing, telecom, and electronics manufacturing soared 107.7%.
What macro tailwinds support the earnings recovery?
April PPI rose 2.8% year-on-year; CPI rose 1.2%. UBS expects inflation to climb further in coming months. In plain terms = mild price increases mean companies can charge more, directly boosting top-line revenue.
Non-financial A-share overseas revenue has risen from 9.5% of total in 2010 to 18.7% in 2025, and overseas gross margins consistently exceed domestic margins. This reflects overseas income becoming an additional engine for medium-term margin expansion.
How does UBS recommend positioning?
Under a base-case "slow bull" scenario, UBS leans toward growth style; the PPI and industrial-profit recovery supports cyclical style; ample liquidity and high turnover favor small-cap style. UBS expects large-vs-small-cap performance to be more balanced in H2 than in 2025.
Six overweight sectors: Electronics (semiconductor inventory cycle + AI innovation), Telecom (AI compute + industrial internet), Machinery (automation + domestic substitution), Non-ferrous metals (copper/aluminum price rises + lithium demand recovery), Chemicals (anti-involution + overseas capacity exit), Electrical equipment (policy support + AI data-center power demand).
The key test: electronics and telecom overweights have already hit prior highs. Whether these positions can hold as earnings deliver will determine if this tech-growth style can run the full three-year window.
