Main Topic
A severe sell-off in U.S. semiconductor shares on Friday set a difficult tone for Taiwan’s equity market as November began. The Philadelphia Semiconductor Index fell by more than 7%, while Taiwan Semiconductor Manufacturing Company’s American depositary receipts (TSMC ADRs) dropped nearly 6%, reaching their lowest level since August. The weakness in major technology stocks has raised concern that Taiwan shares may experience further declines as they catch up with the overseas market.
Market traders in Taiwan expect this catch-up pressure to be hard to avoid in the near term. If the benchmark falls below its six-month moving average, attention is likely to shift to whether selling by investors using margin financing will intensify, and when that pressure may begin to ease. For longer-term investors, the immediate priority may be to wait for market positions to settle rather than assume that prices have already found a durable floor.
Taiwan stocks lost 829 points last week, marking a third consecutive weekly decline. Since October began, the market has fallen 2728 points, turning what is often viewed as a strong month into a notably weak one. Traders warn that this week could bring substantial selling as investors unwind or adjust positions in a market where holdings have become unsettled. They characterize the risk as a systemic market issue: even companies reporting strong financial results may find it difficult to counter broad-based pressure on their own. In such conditions, relative stability may be a more realistic near-term objective than a swift recovery.
Trading by institutional investors has also shown a divergence. Foreign investors recorded five consecutive sessions of net selling last week, while investment trusts registered three consecutive sessions of net buying. This pattern suggests that domestic institutional investors continued to add exposure during the decline, even as overseas investors reduced theirs.
Foreign investors sold a net 1734億元 during the week. Of that amount, 625億元 came from TSMC, while net selling also included 365億元 of MediaTek (聯發科), 284億元 of Delta Electronics (台達電), 236億元 of Yuanta Taiwan 50 (元大台灣50), and 174億元 of ASE Technology Holding (日月光投控). United Microelectronics (聯電) and Nanya Technology (南亞) each saw net selling of more than 130億元. Net selling in Zhen Ding Technology (臻鼎-KY), Yageo (國巨*), and Unimicron (欣興) was above 100億元 for each company. These flows illustrate the scale of the selling and its reach across semiconductor, electronics, and index-related holdings.
Sinopac Securities Investment Service (永豐投顧) highlights an important difference between the current decline and the market’s movement in July: margin financing has not yet fallen substantially. Its review of 25 market declines since 2003 in which the index fell by more than 10% found that margin financing generally began to decrease after the broader market had fallen by about 10%. When the market decline exceeded 15%, panic selling became more likely.
Across those historical periods, the overall reduction in margin financing was about 1.23 times the index’s decline. Financing peaks and troughs also tended to lag the index, with the median financing low arriving 11 trading days after the market low. This lag means that a market rebound does not necessarily coincide with the point when leveraged positions have been fully reduced. Conversely, the persistence of margin balances can leave the market exposed to additional selling if prices continue falling.
In the present decline, the index has retreated about 7% from its peak. Margin financing balances fell from a high of 6533億元 on October 12 to 6339億元 on October 29. That relatively limited decline does not support relying entirely on a wave of margin liquidation as confirmation that the market has bottomed. Still, changes in financing balances remain a useful indicator of how much unsettled market exposure may be left. A declining margin balance can help reveal changing market positioning, but it is not, by itself, proof that a durable low has formed.
For November, Sinopac Securities Investment Service identifies 45000 points, near the six-month moving average, as the key dividing line between its two scenarios. These are conditional possibilities based on current market positioning, not guaranteed forecasts. The first scenario is that the market consolidates and holds above 44600 points. In that case, margin financing could ease gradually as prices move sideways, with the reduction staying within 10%. This would amount to a relatively orderly adjustment without a major wave of forced financing liquidation.
The second scenario would unfold if the market breaks below the six-month moving average and continues down toward the one-year moving average. Under that path, the broad market’s decline could reach 20%, and the financing balance might need to fall to around 4200億元 before conditions stabilize. The difference between the two possibilities is therefore not simply the direction of prices: it also concerns the depth of the decline and how much leveraged exposure is removed along the way.
The moving-average levels and financing estimates should be understood as reference points in a risk framework. They do not establish that support will hold or that the projected financing reduction will occur. Market behavior can be influenced by overseas technology shares, changes in institutional flows, company results, and investor responses to price movements. The analysis instead offers a way to organize uncertainty: a market that holds above the stated threshold with a gradual financing decline would look different from one that breaks lower while leveraged positions are cut sharply.
Valuation offers a separate consideration for longer-term investors. The estimated price-to-earnings ratio for Taiwan’s weighted index has declined from about 21 times at its June peak to just above 16 times. That level is close to the one-year low of 16 times. Lower valuations can increase the potential return available to investors willing to accept risk over a longer horizon, but they do not eliminate the possibility of further near-term declines. The distinction between valuation and timing is important: an index may look less expensive than it did earlier while still facing selling pressure.
Taken together, the market picture is mixed. The external shock from U.S. semiconductor shares and continued foreign selling point to immediate risks, while domestic institutional buying and a lower index valuation offer countervailing observations. Margin financing remains a central variable because its adjustment may affect how the market absorbs further weakness. Rather than treating any single indicator as decisive, investors can follow price levels, trading flows, and financing balances as related but distinct signals.

Afterwards...
The next stage of market analysis will benefit from closer study of how financing balances, institutional flows, and index levels interact during periods of stress. Historical patterns can provide context, but they cannot determine exactly when investors will sell or when a market will stabilize. More timely and transparent data on leveraged positions could help analysts distinguish orderly reductions in exposure from forced selling, while careful comparison across past market cycles could clarify how reliable different warning signals have been.
Technology and knowledge areas worth exploring include improved measures of market liquidity, more detailed monitoring of cross-market connections, and analytical tools that explain how overseas semiconductor movements affect Taiwan-listed companies. These approaches could help investors and researchers evaluate whether a decline is being driven primarily by global risk repricing, local positioning, or company-specific conditions. The most useful progress will come from combining better data with clear limits on what any single indicator can establish.
For now, the key questions remain whether the market can hold the identified levels and whether financing balances decline gradually or sharply. A disciplined assessment of those developments, alongside valuations and corporate fundamentals, can help keep short-term volatility in perspective without assuming that either scenario is certain.
