$UMC Watching this for Monday. Not too interested in taking a position right now, based on the minute chart in the comments. Lack of candles means lack of interest, either way, but trending over the 50-day (red line) is a good start. The high of the day was @ 9:30, so not enough movement to warrant a buy for me. My guess 7.09-7.16 is the price range to end the day (unless some major news is released, but worth watching.

$MCHP sitting at $66 with volume slightly below average, while $UMC trading at $7 with significantly lower volume. MCHP showing more stability compared to UMC. Are the Chips sector dynamics influencing these diverging trends?

$UMC United Microelectronics Corporation is a major Taiwanese semiconductor foundry. It is a second-tier player behind TSMC and specializes in more mature nodes. It is a cyclical play on semiconductor demand and trades at a lower valuation than its peers.
