Optical communication stocks lead the rebound; will the AI optical cycle continue?
1 $Lumentum (LITE.US)$ LITE surged to $970 at the open yesterday before experiencing some intraday pullback. Interestingly, by the close, the price rebounded from $920. The daily chart closed with a doji star featuring a long lower shadow, indicating solid buying support at lower levels.

Looking at the moving averages, if LITE can pull up above the 5-day MA and quickly cross above the 10-day MA, it will form a new short-term bullish alignment. For investors who reduced their positions at yesterday's highs, you may hold your remaining core position, with the next upside target around $1,050. However, for those who missed the rally entirely, a more aggressive approach is now required. I suggest $930–$910 as the zone for initiating the first tranche of positions. To be clear, this is not bottom-fishing at low levels but rather buying the pullback of a strong stock at high levels. Therefore, be prepared for a potential second correction. Keep the initial position size small; if further adjustments occur due to market conditions, we will determine the entry point for the second tranche based on the prevailing environment.

2 $Marvell Technology (MRVL.US)$ MRVL released its latest earnings report after hours. Despite revenue slightly exceeding expectations, the stock fell nearly 8% instead of rising, likely because the share price had already priced in part of the expectations beforehand. The stock price returned to around $220. However, for those who missed out on MRVL previously, this post-earnings pullback may not necessarily be a bad thing. MRVL has exposure to both optical interconnects and custom chips. If you remain bullish on AI infrastructure, I believe $220–$212 is a decent range for initiating the first tranche of positions, with the first upside target around $275.
Let me also update you on UMAC, the drone concept stock recommended yesterday.
The stock staged a very nice oversold bounce yesterday, closing up over 10%, with the price returning above $26. From a weekly perspective, UMAC executed a standard technical rebound after testing the 10-week moving average. If you participated at the lows, consider taking some profits after today's open, while holding your core position for the next target of $30. If you completely missed UMAC and feel that sentiment in the main tech theme is lacking, prompting you to chase hot themes, I view the area around $25 as an aggressive re-entry point. However, it must be emphasized that UMAC does not follow the same logic as the main tech theme; it lacks strong earnings certainty and is driven more by thematic speculation and technical trading. Therefore, averaging down is not suitable for this stock. If you insist on entering at $25, reduce your position size and set $22 as a clear risk-control stop-loss level.
