United Microelectronics Corporation stock analysis
Everything behind the call on United Microelectronics Corporation. 6 sections, ordered the way risk stacks up: survival first, quality and price in the middle, context last. The Beacon gives you the read. This is where you check the work.
The five reads
Why the reads disagreeread this before the sections
Event and Quality are pulling against each other and the split is genuine rather than a formality. The net lands at 0 over 30d, a balanced reading on a dispersion of 0.45, which makes this a question of size rather than of direction.
Leans up · and why
earnings, sentiment vote up. 2 of 4 independent evidence families agree.
Leans down · and why
quality / value, insider flow vote down. 2 of 4 families lean the other way. The conflict that matters is Event against Quality.
What it changes
Size, not direction. dealers are long gamma, so their hedging absorbs moves rather than amplifying them; separately, the tail model puts a very bad day at −11.5%; and the binding position cap is 3.3% — the tail cap is the one that binds.

↳ Plain EnglishA multiple is what the market charges for a dollar of this company's earnings, cash or revenue; the trend and the options tape say what the price is doing around it. Together they are the timing picture, not the quality one.

How to read this
Up 0.57% on the session.
Follow the solid line: each point is a session close. Compare it to the 50-day average — while price stays above it the short-term trend is up, and a drop below is the first structural warning.
The dashed levels are the strikes the options chain is most committed to. They are the same numbers the gamma block states; nothing here is drawn that no section derives.
Momentum (RSI-14)WARM
69
030 oversold70 hot100
Where momentum sits on a 0–100 scale. Above 70 is overbought, below 30 oversold; the middle says the move has room either way.

Where price sits inside its own volatility band. The edges are where a move is stretched, not where it reverses.

The volume-weighted average of the last month. Price above it means recent buyers are, on average, in profit.

1 of the 8 priced multiples above sits in the richer half of its band. Each priced multiple is read against this stock's own history where a five-year range is on file, so the question is whether today is dear for this name rather than for the market. The multiples are computed separately from the quote above and are not re-priced as it moves, so they can lag it.

8 surfaces checked, 4 clear. The binding constraint is position size — the tail cap is the one that binds. Each row states which surface it is and what it measured; a surface that could not be scored says so rather than counting as clear.
