$UMC I'm loading as much as I can. Once this moves out $23 $25 range, I won't be able to load this low again.

$UMC Any second now we commence our ascension, they wanted to scare weaks. They don’t realize weaks sell , longs get to double up and add to their position. Not financial advice consult your financial advisor.

$UMC make 5% in this market? Sideways or lower will kill you! B careful peeps. I read a few posts who bought at 23, 22 thinking it SHOULD go to 30! No way. Read charts, learn PE and read financials! 42-year-old fart who you can hate! I do not care. Trying to help you to be better!

$UMC $17 dollar is poe. point of entry if u do charts. I do. the 17 puts in the right shoulder for a head n shoulder reversal inverted. Scan out the 10 year and you'll see. My opinion. 42 years of this and counting.

$UMC Interesting how a little over 2% future dilution with the convertible bonds issued resulted in the decline after the news was announced. Revenues are still increasing: 27.22% YOY September and 16% YOY Jan -Sept Not financial advice, do your own due diligence. Best!

$UMC getting some big play today Saw a 12.4k-contract Jan 2028 $30 call golden sweep on InsiderFinance Over $6.2M in premium means at least one big player is betting on long-term upside even with today’s 10% dump This selloff comes after that $1.8B zero-coupon convertible bond announcement Near-term dilution risk is real so don’t expect a quick rebound All the options flow in the last 5 days is call-side with 0% puts Averaging 447 days to expiry Seems like the smart money is looking way out rather than short-term pops Intraday traders should be cautious about expecting a fast reversal here

$UMC Oct 28 looks like earnings. August sales up 30% YoY. Predicting an incredibly strong print and details on its move into AI-photonics and Singapore expansion. Massive capex but this is a monster company.

$UMC So $7 lower from 23-24 and I am hated for saying no until 12? SMH! Learn when to buy please or short too! GLTA! btw, it WILL get worse!

$UMC from a trading perspective, I made the right move bailing on Tuesday for a very small gain, but I don’t think the drop is justified. PPS should be over $30

$UMC is ranked #15 in technology momentum. I used Stock Meadow’s scoring model to review the scores. What do you think?

$UMC earnings thoughts? looks a little like a check back in 2028 story when the photonics money starts to roll in.

$UMC Q3 '26 Earnings Results & Recap UMC's Q4 2026 guidance calls for wafer shipments to increase by low-single digit, USD ASP to remain firm, gross profit margin comparable to preceding quarter, and 2026 CAPEX of US$2B.

$UMC reports earnings tomorrow before the open. I used Stock Meadow’s earnings dashboard to review its history: UMC has beaten EPS estimates in 5 of its last 8 reports. What are you watching for?
