You’ve raised a very timely question regarding whether the ongoing rally in the NAND/DRAM (memory-chip) sector is still a viable entry point — using Micron Technology (“Micron”, ticker MU) as a proxy. Let’s walk through the key considerations: what’s driving the move, what the risks are, and whether at this stage there remains an attractive opportunity (and how that aligns with your situation). This is not investment advice, just a reasoned perspective.

✅ What are the bullish drivers
There are several strong tailwinds supporting the idea that the memory space (including NAND flash) may be in a structural up-cycle:
1. AI & data centre demand
Micron itself states that “AI-related business … is also fuelling demand for storage chips, known as NAND flash”, and that its data-centre business is at all-time highs.
The broader memory-market outlook observes that AI is “devouring the majority of the global memory and flash capacity” through 2026 and beyond.
Other analysis shows that one in five NAND bits will be used for AI applications by 2026, and the NAND market is forecast to rise to ~USD 65 billion in 2026, ~USD 70 billion in 2027.
2. Supply constraints and pricing power
Analysts highlight tight supply for NAND and DRAM: for example, one source argues that the NAND cycle is turning, with “lead-times are lengthening, allocations are tightening” and supply constraints likely into 2027.
Micron expects memory supply to remain tight into next year, per its commentary.
3. Company-specific strength
Micron has recently delivered ahead of estimates (in Q4 per its September report).
Analyst commentary: e.g., an upgrade following strong demand for memory tied to AI, which suggests the market may still be under-appreciating the scale of opportunity.
In short: yes, there is a credible bull narrative for the memory chip makers, and Micron is very much part of that story.

⚠️ What are the potential risks / caveats
However, the picture is not without significant caution flags — which matter especially if you are risk-sensitive or investing at this juncture:
1. Cyclicality and past market exuberance
The memory sector has historically been highly cyclical (booms and busts as capacity/investment swings, pricing, inventory, etc). Even strong demand can be offset by sudden capacity ramps or macro slowdowns.
One article notes that although Micron has rallied strongly (over 80% in 2025 at one point) the key test is whether this is a sustainable structural shift or just a near-term surge.
2. Valuation and expectation premium
Given much of the good news (AI demand, supply constraint) is already priced in (or partially so), there is less margin for error.
If guidance disappoints (for example, margin pressures, slower growth than expected), the share may be vulnerable. In fact, earlier in 2025 Micron’s shares dropped on a weak margin forecast despite favourable revenue outlook.
3. Possible over-extension / big run already
If you’re entering now, you may be buying after a big part of the gain. That means future upside might be smaller and downside risk larger.
One piece suggests Micron may be “too cheap to stop buying”, but also notes the rally already makes risk/reward less advantageous than earlier.
4. Execution risk
Supply constraints are good in one sense (higher pricing power), but bad if the company cannot ramp capacity or suffers margin erosion due to cost inflation or technology transitions.
Memory companies are investing heavily (Micron’s spending in 2025 was US$13.8 billion on plants/equipment) to meet the demand, which means large capital outlay and risk.

🎯 My view — does it still make sense to join now?
Given your situation (you prefer affordable options; you’re cautious; you emphasise steady working towards goals rather than high-risk gambles) here is how I’d frame the decision:
The bullish case for memory (including NAND) is strong, meaning that if things go well, returns could be very favourable.
But entering at this stage (after a big run) carries more risk than earlier in the cycle: less margin for error, and more dependent on flawless execution and favourable market conditions.
Therefore: you could consider a partial exposure or a smaller position, rather than a full commitment, if you want to participate. If you prefer low-risk, you might wait for either a pull-back or further confirmation (e.g., guidance increases, margin improvement, signs of structural change).
If you enter, ensure you have a stop-loss or risk-control strategy (given the cyclical nature). And align the size of the investment with your comfort level (especially since you said you focus on “affordable options”).

📝 Specific to Micron (MU)
Micron is a direct beneficiary of the AI/memory tailwinds, and analysts are bullish on its outlook.
However, given its strong rally already, the potential upside may be more limited and the “easy money” may have been made.
It could make sense if you believe 2026-2027 will bring structural change (not just a cyclical bump) in memory pricing and utilisation.
If you are less confident about that, or prefer smoother outcomes, you might wait or spread out your entry.
