GlobalFoundries partners with TSMC to establish US-based production of silicon interposers
Partnership announcement that GlobalFoundries is cooperating with TSMC to begin production of silicon interposers in the US
Currently trading at $48.07, which is between the resistance line at $50.99 and the support line at $42.04, it was purchased as there remains room for upside given its proximity to the resistance level. Additionally, consideration was given to the likelihood that news of the GlobalFoundries-TSMC partnership would act as a positive catalyst.
If the stock price reaches the resistance level of $50.99, take profit; if it falls below the support level of $42.04, cut losses. Currently purchased at $48.07, the target will be achieved if a breakout of the resistance level is confirmed, and losses will be cut if a breakdown of the support level is confirmed.
RSI(14) at 58.9 – neither in overbought nor oversold territory, showing a slight upward bias from neutral; moving averages not in a proper alignment – trend remains unclear as moving averages are not distinctly aligned; trading volume at 0.79x the 20-day average – strong wait-and-see sentiment amid below-average volume; 7-day volatility +0.6% – minor increase.
In the past, GFS showed minor fluctuations from 2026-10-14 to 2026-10-17, moving -0.4% → -2.2% → -2.2% → -2.2% → +2.2%, without major trend reversals, sharp surges, or plunges. As a similar success case, there was an instance on 2026-08-04 where GFS rose 10.9% following the release of identical GlobalFoundries-related news (with overlapping keyword 'GlobalFoundries'). This is directly related to the current partnership news. Cases involving VEEE (2026-07-16) and LRCX (2026-07-06) recorded very high returns, but are mentioned for reference only as the respective stocks and news contents are not directly similar.
The projected return of 3.2% was predicated on breaking the resistance level at $50.99, but the stock actually fell below $42.04, recording a loss of -12.8%. Although the RSI was at a neutral level and trading volume was below average, upward momentum was overestimated, and the pattern of historically small price fluctuations was not sufficiently reflected. The main cause was buying near the resistance level without fully considering the downside risk.
For the next trade, the guiding principle is to enter only after confirming a breakout above the resistance line. If a downward movement of 2-3% or less is observed immediately after entry, the stop-loss should be adjusted upward immediately to a level slightly above the stop-loss price of $42.04 (e.g., $43). In addition, expectations for an upside should be increased only when trading volume rises to 1x or more of the 20-day average and the RSI shows an overbought signal of 60 or higher. SEC filings and thematic news flows should continue to be monitored, while avoiding overreactions to general INFO-level disclosures.
