Taiwan's stock market had its best week globally last week, but a U.S. chip stock selloff Friday puts it at risk of a sharp pullback Monday — mixed news for Taiwan investors.

• Taiwan stocks jumped about 10% last week, the best performance of any major market, helped by government fund buying.
• Nvidia and AMD fell hard in the U.S. on Friday, and that weakness is expected to drag Taiwan chip stocks down Monday, with support seen holding near a key level before another push higher is possible.
• Foreign investors sold Taiwan stocks heavily in October but started buying again as the rally took hold, a sign money may be coming back in.
• Nvidia reports earnings this week in its first major update since founder Jensen Huang resigned after an affair and spying allegations, and that report plus Anthropic's stock market debut will set the tone for AI stocks.
• Experts say Japan's push to undercut Taiwan's TSMC on advanced chip pricing is unlikely to work, since Japan lacks the production quality and customer base to really compete, leaving TSMC's lead intact for now.

Outlook: Taiwan stocks likely dip Monday on the U.S. chip selloff, with Nvidia's earnings this week a key test for whether the rally can resume.
