Chapter 1: Anatomy of the Taiwan Stock Crash
1.1 Three Consecutive Days of Foreign-Investor Exits
According to the Jinxingren (Venusian) morning investment briefing on May 14, foreign investors began selling TSMC in succession:
| Date |
Foreign-Investor Movement |
Notes |
| May 11–13 |
Cumulative net sales of ~27.85M TSMC shares |
Foreign holdings continue to fall |
| May 13 |
TSMC fell 1.55% in a day |
Decline exceeds market's 1.25% |
| VIX index |
Reached 17.99 |
Approaching the psychological 18 threshold |
This selling pressure is not without cause. Multiple bearish factors are intertwined: the US Federal Reserve delayed rate-cut expectations due to stubborn inflation, oil prices broke above US$100 per barrel, and the Trump–Xi meeting created geopolitical uncertainty. The technicals also flashed warnings — TSMC's MACD histogram widened, and momentum indicators showed weakening upside momentum.
1.2 Risk Indicators at a Glance
Risk assessment of the Taiwan stock portfolio shows significantly elevated volatility:
| Risk Indicator |
Value |
Assessment |
| VaR 95% |
-2.89% |
Maximum one-day loss at 95% confidence |
| VaR 99% |
-4.23% |
Maximum one-day loss at 99% confidence |
| Max drawdown |

| Annualised volatility |
38.44% |
Significantly above prudent investment standards |
| Risk score |
5/10 |
Medium-to-high risk level |
Volatility of 38.44% means that, statistically, TSMC's share price could swing ±NT$854 around the NT$2,220 base. For investors seeking wealth preservation rather than speculation, such volatility represents unsettling uncertainty.
1.3 The Psychological Pressure of Stop-Loss Anxiety
What most worries risk-conscious investors: the traditional defensive stock Hua Nan Financial (2880) is currently at NT$32.55, just 0.76% above its stop-loss price of NT$32.50. This precarious position forces investors into constant monitoring mode, where emotional decisions often override strategic planning.
