$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 Stock has been weak technically, but I'm still up 60% in 6 months. Holding, not trading. Interesting parallel with Intel.

$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 So I see a lot of garbage comments around why not to buy Intel and nothing about buying this. It may not go to 1k overnight but steady growth in next few years could lead to massive gains. I took profits a while back but I’m back in and have a good feeling about this company similar to TTMI and sold years ago in the teens.

$UMC Took some profits at $25. 33% gain in 1.5 months not too shabby. Letting a good chunk ride still.

$UMC Already beat my $FXAIX 401k investments by 2x in gains for the year not even accouting for the free divis! Ending the year with another 2x! 🫡

$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 is number 22 on the NYSE strong buy list this morning. I'm up 12.7% and it's up 27% the past 3 weeks. It's beating the SPY on the 1m, 6m, and 12m. Not the 3m graphs. Set an alert/stop. Good to all Dr. Stoxx (plug) and mainstreet traders around the world.

$UMC this is that semi-conductor stock $SMH that got killed a few days ago on news of offering a convertible pfd. it lost about -9.75% on that day. trying to reenter at 23.06 just 101
evel2022
$UMC So now the theme is, if it is not USA operated then it needs to be investigated. If it is in Asia, then it is China related with a security threat to the USA. Man, the chit that is made up to keep the money wheel turning!

$UMC this will catch on quick that this dropped a lot when at most it should have dropped a little. I’m looking at a 8 to 10% bump to the upside off of the over reaction.
jewell69
$UMC stock got killed yesterday 10/5 -10% because they issued a convertible pfd. unable 2 buy at 23.83 or 23.77 today, b 100 23.26; it is already down another 2 eyelashes to 23.145. new topic. I will study the pfd of $GOOG the symbol is $GOOGN cnbc people talking about it. THEY SAY (not me) 6.4% divvy.
atmostrunmoney
$UMC My take is you don’t load up when is running, in my opinion this is the right time to load up. Not financial advice talking out loud to myself.
