Stocks to Watch Today: AI Memory Rally or Big Tech Reality Check?

The market is giving investors two very different messages today.

On one side, memory stocks are rallying on the back of SK Hynix’s record results and continued demand for AI infrastructure. On the other, investors are becoming more selective about how much technology companies are spending on AI — and whether those investments will generate enough returns.

That makes today’s market interesting. I would not chase every stock that is moving higher. I would rather identify which companies have improving fundamentals and which ones need to prove that their valuations are justified.

1. Memory stocks: strong earnings, but how much optimism is priced in?

Stocks to watch: SNDK, MU, SK Hynix

SK Hynix reported record third-quarter revenue of KRW 104.6 trillion and operating profit of KRW 83.3 trillion. Its results reinforced the strength of demand for memory products used in AI infrastructure.

Micron and SanDisk also rallied as investors reassessed the outlook for memory and storage pricing.

The investment case is straightforward: AI infrastructure requires not only processors, but also high-bandwidth memory, conventional DRAM and increasingly capable storage. If demand continues to outpace supply, manufacturers could maintain strong pricing and profitability.

However, I would not assume all memory stocks will benefit equally. SK Hynix has substantial exposure to HBM, while SanDisk’s business is centred on NAND flash and storage. Micron has exposure across DRAM, HBM and NAND. Their product mixes, margins and valuations differ.

My plan would be to watch SanDisk’s earnings and forward guidance closely. A revenue beat alone may not be enough if investors are already expecting exceptional results. I want to see evidence that pricing strength is translating into sustainable margins and cash flow.

My view: The memory cycle remains worth watching, but after a sharp rally, I would rather wait for earnings confirmation than buy simply because the sector is green.

2. Big Tech: AI spending is becoming a test of returns

Stocks to watch: GOOGL, MSFT, AMZN

Alphabet’s latest results have reignited concerns about the cost of AI infrastructure investment, while Microsoft’s results have offered a more constructive signal on cloud growth and cash flow.

This divergence matters. Investors are not just asking which company spends the most on AI. They want to know whether that spending can generate enough revenue, improve profitability and defend competitive advantages over time.

Amazon is another company to watch, with its results due after the U.S. market closes today. I would focus on AWS growth, operating income and management’s capital expenditure outlook. For a business investing heavily in infrastructure, the relationship between spending and future cash generation is particularly important.

I would apply the same principle to Microsoft and Alphabet: distinguish productive investment from spending that may take longer than expected to earn an adequate return.

A large AI budget is not automatically a negative. But neither is it proof that a company will create more shareholder value.

My view: I would prefer companies that can demonstrate improving returns from AI investment over those relying mainly on the promise of future growth.

3. Intel: an earnings catalyst, not an automatic bargain

Stock to watch: INTC

Intel is also due to report results after the U.S. market closes on 29 October.

The key questions are whether its business is stabilising, whether its manufacturing strategy is progressing as intended, and whether management can provide a credible path towards sustainable profitability and cash generation.

Intel is a different investment proposition from a high-growth memory stock. Its potential upside depends not just on demand for chips, but also on execution, competitive positioning and the economics of its manufacturing operations.

I would not buy solely because the market expects a turnaround. I want evidence that the turnaround is happening.

For event-driven trades, earnings can produce sharp moves in either direction. Even a company that reports improving results can fall if the outlook disappoints.

4. Hong Kong stocks: selective opportunities, but sentiment remains fragile

The Hang Seng Index edged higher on 29 October, trading around 23,100, while technology shares remained under pressure. The Hang Seng TECH Index slipped in early trading as investors reacted to weakness in U.S. technology shares and continued uncertainty around AI investment returns.

I would watch Tencent (0700.HK), Alibaba (9988.HK) and Xiaomi (1810.HK), but I would not treat them as one trade. Their growth drivers, valuations and exposure to consumer demand and AI differ.

For Hong Kong-listed stocks, I would look for stabilising prices accompanied by stronger turnover and improving company-specific news. A small index rebound is not enough to establish that a durable recovery has begun.

My trading plan

I am approaching today’s market selectively rather than trying to predict every short-term move.

First, I would watch the memory sector for confirmation that strong demand is translating into forward earnings growth. Second, I would assess Big Tech results based on cash flow, cloud growth and the expected returns on AI spending. Third, I would keep some cash available rather than committing everything before major earnings announcements.

I would also distinguish a long-term investment from a short-term earnings trade. A company can be an excellent business but still be a poor entry at an excessive valuation.

For me, the best opportunities emerge when the fundamentals improve faster than market expectations — not simply when a stock has the biggest daily gain.
