Sector and Stock Summary: Comprehensive Trading Review of Memory Chips, Optical Modules, Data Centers, and Tech Stocks

1.Memory Chip Sector

If I had to choose between memory chips and optical modules right now, I would still lean more towards memory chips.

The core logic remains driven by AI demand, rising memory chip prices, and tight supply-demand dynamics. Additionally, overall valuations and industry scale offer certain advantages.

$Micron Technology (MU.US)$ For MU (Micron Technology), if you entered positions near $930 previously, continue to hold; there is no need to repeatedly add to your position around $940. Those currently out of the market can patiently wait for the $860–$880 range.
$SK hynix (SKHY.US)$ For SK Hynix, continue to hold existing low-cost positions.
$SanDisk (SNDK.US)$ For SNDK (SanDisk/Western Digital), if you entered near $1,450 previously and have accumulated some profits, consider taking partial profits based on your position size, while retaining your low-cost core holdings. Those currently out of the market should not chase the rally; a new entry point to watch is around $1,350.

2.optical module sector

LITE (Lumentum) saw a relatively significant correction yesterday, but the declines in COHR (Coherent), MRVL (Marvell Technology), and AAOI were generally manageable.

For LITE, if you already hold positions established near $900, continue to hold; there is no urgent need to add to your position at this time.

For MRVL, the key focus remains on scaling into positions at specific intervals. Consider $210 as the first entry point for observation, and look to add a second position in the $180–$190 range. If you already hold a position near $230, do not continuously average down just to lower your cost basis by a few dollars.

$Coherent (COHR.US)$ COHR continues to wait for a bullish reversal. If it subsequently breaks through $320 and further approaches the $340 level, consider pyramid-style position adding based on the trend.

For AAOI, continue monitoring for a high-volume breakout above $122. After the breakout, watch the $125–$126 zone.

3.Data center and AI infrastructure support

CRWV and NBIS also corrected today due to broader index weakness, but my long-term thesis regarding data center orders and demand logic remains unchanged for now.

CRWV still requires patience as sector capital flows back. Do not add indiscriminately until a clear second buy point emerges.

If you already hold a position in NBIS near $198, continue to monitor. $220 is a critical level for trend confirmation.

CLS also belongs to a sector with relatively clear fundamentals and earnings expectations. However, as the broader index has not fully strengthened, maintain existing positions rather than rushing to add more.
