Lam Research $LRCX broke below its daily moving average (now ex) support band, and despite the +18% move on Thursday, price closed the week below that band, while respecting its descending MA resistance.

@NasdaqFrontier6· StockTwits4h ago

Q2 Earnings Winners So Far The biggest earnings reactions are showing one clear theme: Strong execution is still being rewarded. Semiconductors $AXTI +28.74% $FORM +26.28% $AEHR +21.91% $SIMO +21.66% $LRCX +17.98% CLS +10.04% The takeaway: The market is rewarding companies with: • Real revenue growth • Strong margins • Clear demand trends • Positive guidance AI remains a major driver, but opportunities are expanding into cloud, infrastructure, industrials, and specialized technology. The next winners may come from the companies quietly building the future. Follow me and visit my profile for earnings breakdowns, AI infrastructure research, and high-conviction growth stock ideas before Wall Street fully prices them in.

5 Undervalued Stocks With Massive Upside Potential The biggest winners are often found before the market fully understands the opportunity. My watchlist: $CRDO — AI data centers need faster connectivity. High-speed interconnect is becoming a critical bottleneck. $MRVL — Custom silicon, networking, and optical solutions will benefit as AI infrastructure expands beyond GPUs. $HOOD — A next-generation fintech platform with growing users, products, and long-term monetization potential. $SNDK — Memory is becoming one of the biggest AI bottlenecks. HBM and data center demand could drive a new cycle. $LRCX — The semiconductor equipment layer powering every advanced chip buildout. The common theme: AI infrastructure. Semiconductors. Digital finance. The next generation of market leaders may already be building today. Which one has the biggest upside?

$LRCX have a read, the sell off last week was tied to Citadel and this hedge fund https://www.nytimes.com/2026/07/31/business/situational-awareness-leopold-aschenbrenner.html

Evercore ISI Reiterates Outperform on Lam Research, $355 PT — PT $LRCX https://price-target.com/2026/07/21/172704/

@skcots_13· StockTwits1d ago

$LRCX Submitted for your approval: In a dimension of silicon and plasma, where fortunes are etched at the atomic scale, Lam Research stands as the specialist—1st place master of high-aspect-ratio etch and a clear second in deposition. Its most direct rival, $AMAT Applied Materials answers with a broader arsenal across the wafer-fab process. Nearby, $KLAC watches with the cold eye of inspection and metrology, while $ASML commands the solitary realm of EUV lithography. Lam’s edge is depth, not breadth: enabling the most demanding steps for 3D memory, advanced logic, and AI chips at every critical inflection. They are all fine investments and buys, IMO. Nothing wrong with that. Yet in this twilight zone of endless scaling, the real contest may not be market share… but how long the human mind can outrun the machines it creates.

THE AUGUST OUTLOOK - TIME TO BUY THE DIP? What are the charts signalling for the market going into August and which stocks are setting up for a move? $NBIS $IREN $SOFI $NFLX and $LRCX all fully assessed plus another 20 top trade ideas for your watchlists. 👇 https://www.honeystocks.com/analysis

@MarketPulsee· StockTwits2d ago

If you missed this week's earnings, here's a recap of our positioning: Bullish: $MSFT $LRCX $AMZN All three reacted strongly after earnings. Bearish: $META The stock moved lower following the report. No high-conviction view: $AAPL Apple beat expectations, yet the stock still sold off as investors focused on valuation, margins, and AI expectations rather than the headline numbers. Earnings season isn't just about whether a company beats estimates. It's about how expectations compare with reality. This week reinforced the importance of focusing on positioning, guidance, and market expectations—not just the headlines. What earnings surprised you the most this week?

@JE1213· StockTwits2d ago

$LRCX anyone see the crazy 382.48 right after close?

@skcots_13· StockTwits2d ago

$LRCX Shanghai SMEE lithography:SMEE (and its closely linked state-backed ecosystem, including Aishengna) can now produce immersion DUV tools at roughly the 28 nm single-exposure level (comparable to ASML machines from ~2008!!!!). These are entering limited production (~5 units targeted in 2026, ~20 in 2027) and are being delivered/tested at Chinese fabs like SMIC, Hua Hong, and CXMT. Why it doesn’t hurt LRCX because does not make lithography tools. Its core business is etch, deposition, and related process equipment. Chinese fabs still need those tools to actually build chips, even if they use domestic DUV scanners. More domestic lithography capacity can actually increase demand for etch and deposition steps — especially with multi-patterning, which requires extra deposition and etch cycles. Recent LRCX results and guidance already showed strong AI-driven demand outside China more than offsetting softer domestic Chinese spending.

@skcots_13· StockTwits2d ago

$LRCX Recent China news on 07//27/26 that a Shanghai-based, state-backed firm began mass-producing immersion DUV lithography tools for delivery to Chinese chipmakers (including SMIC, Hua Hong, and ChangXin). Lam Research reported June 2026 quarter results on July 29 that largely overshadowed those jitters. With Revenue $6.72B +15%, +30% YoY beats. Non-GAAP EPS $1.82 beat. Gross margin ~52%,Strong September quarter guidance: revenue $8.1B ± $400M and ~20%+, with solid margins and EPS. China fell to 26% of revenue from 34% in the prior quarter. LRCX’s core strengths benefit from rising process complexity even if lithography advances domestically in China. In short, the latest China lithography news amplified existing geopolitical concerns and contributed to a temporary pullback, but Lam’s guidance indicate that AI-driven non-China (and multinational-in-China) demand is absorbing the impact for now. Just structural risks rather than an immediate growth killer.

$LRCX Chinese machines and competition taking market share away-far from the truth...
