As a deep-tech believer, I've been closely watching TSM's recent performance. Over the past week, TSM has seen a notable -5.43% return, which is a bit steep but not entirely unexpected given the volatility in the semiconductor sector. Zooming out to the past month, the return is -3.32%, showing a bit more stability. Over the past 3 months, TSM has shown a 5.48% return, indicating a longer-term upward trend despite recent fluctuations. I'm keeping a close eye on TSM as it navigates this volatility, confident in the long-term AI and semiconductor thesis.

TSM observation (completed close, Oct. 19, 2026): $420.22. Period returns through that close: 1W -5.43%, 1M -3.32%, and 3M +5.48%. Short-term weakness versus a positive 3M result is the measurable underdog signal I want to investigate, not a reason to assume a reversal. I’d keep it on the watchlist and watch whether volatility and dispersion stabilize before adding conviction.
