Taiwan stocks dropped nearly 2,700 points early on July 8, with the benchmark index sliding from around 42,000 to the 39,300 level in a sharp move that raised concerns over leverage-driven selling. According to institutional market commentary cited in the source, the sell-off was seen as a long-position shakeout after a strong rally rather than a fundamental change in the AI story. By late morning, losses had narrowed by more than 1,000 points as bargain hunters began to step in.
TSMC’s monthly support level is the first key signal
The first indicator centers on TSMC, widely viewed as the market’s anchor stock. TSMC ADR fell 6.69% last Friday and pulled back toward its monthly moving average. Based on the local share price, that level is around TWD 2,293. During intraday trading, TSMC touched a low of TWD 2,230 before rebounding to TWD 2,320, suggesting buying interest emerged in that range.
Using the previous close of TWD 2,365, a 6% pullback points to roughly TWD 2,220. The source notes that this area could become a critical defense line for bulls. If that zone holds, it may serve as an early sign that broader market selling pressure is easing.
Margin maintenance and technical stretch remain under review
The second focus is market positioning. Taiwan’s margin balance stands at TWD 566.6 billion, while the market’s margin maintenance ratio is about 198.98%. That remains above levels considered dangerous, but institutional analysts said traders should watch whether closing data slips toward 140% or even nears the 130% margin call threshold.
They also pointed to the index’s 60-day moving average deviation of 17.63%, which is still above the long-term average of 12.1%. That suggests technical froth has not fully cleared. Losses narrowed during the session, but the source said the leveraged overhang has not yet been fully washed out.
Sector rotation may show whether market structure is changing
The third indicator is where money flows next. Main technology groups such as passive components, ABF substrates, PCB, optical communications, and memory have each posted gains of more than 200% this year, according to the source. After the sharp pullback, investors will be watching to see whether bargain buying returns to those names.
At the same time, sectors including financials, domestic demand plays, food, telecom, and utilities are seen as lower-base defensive groups. If capital rotates out of electronics and into these segments, that would point to a more visible shift in market leadership.
US CPI and the June FOMC meeting are the two external variables
Beyond local positioning, two upcoming US events are highlighted as major variables. The US is set to release May CPI data on June 10, the final major inflation reading before the next policy meeting. Then on June 18, the FOMC rate decision will be announced. Markets are waiting for comments from new Federal Reserve Chair Warsh on labor conditions and inflation trends.
The institutional view in the source is that, with volatility still elevated and margin positions not fully settled, chasing prices is risky. A staggered approach and close monitoring of TSMC’s monthly support, along with the market response to both US events, remain the main points of focus.
