Common questions about UMC’s checks

How many technical checks does UMC pass right now?

As of the Aug 26, 2026 close, UMC passes 7 of 10 fixed technical checks — the checks not passing: market trend rising, long-term trend rising, no recent earnings miss.

Why does UMC fail the "market trend rising" check?

The S&P 500 ($766.08) is below its 10-day average ($768.72), so the market-trend check fails for every stock today, UMC included. It clears market-wide when the index reclaims $768.72.

What price would change UMC's check count?

The nearest flip level is "holding above short-term average" fails on a close below $18.91. Each price-anchored check has an exact next-close level, shown in the Flip levels panel above.
