The market is lagging badly on CXL demand for Astera Labs and Marvell. The next two quarters for both companies will show just how demanding the industry has already become. x.com 

Astera Labs is the next potential 10x long-term play for a young investor with high risk tolerance, as a leader in AI infrastructure connectivity whose semiconductor solutions power hyperscalers' rack-scale systems. x.com 

Astera Labs looks relatively expensive because similarly fast-growing AI infrastructure names trade at much lower multiples. Broadcom and Nvidia are at 14x, Credo at 15x and Lumentum at 18x; comparable peers look 50-80% cheaper. Astera is a great company and not necessarily expensive in absolute terms. Its roughly 2x multiple over Credo may persist, but the setup looks harder; with no valuation support, it could fall 50% if weakness continues. x.com  x.com  x.com  x.com 

An early AI buildout, healthcare data, tokenized finance and copper's clearest supply-demand imbalance favor a 15-stock growth basket now. Marvell, Applied Optoelectronics, Nebius, Eli Lilly, Tempus, Ouster, Regal Rexnord, Bloom Energy, Fluence, SpaceX, Brazil's EWZ ETF, Nu Holdings, Coinbase, Securitize and the COPX copper-miners ETF are the picks. Keep Fluence smaller; SpaceX stays bullish long term despite rejecting $500B-$1T ARR in 2027. x.com 

Alphabet's AI capex payback is being repriced, making its post-earnings decline more than a one-day mood swing. Guidance and cloud and AI margin commentary are the near-term tests. If growth continues but the multiple compresses, the risk is duration in mega-cap AI, not a collapse in technology growth. x.com 

Marvell's management is running the stock as a pump and dump to move shareholders' money into their own pockets. Wall Street prices Marvell as an ASIC design house without realizing that ASIC design is just IT outsourcing. It is not a real CXL play either: CXL IP is sold by Cadence, Synopsys and Rambus with no moat, and Astera Labs, which builds the switches and software around CXL, is the only good CXL play. x.com 

Weak AI sentiment is constructive for AI leaders because weaker hands leaving can concentrate gains in the strongest companies. The stack's leaders are Broadcom in custom silicon, Micron in memory, Vertiv in power, Credo in connectivity, Nebius in neoclouds, and SPCX in orbit and space compute. x.com 

Marvell's after-hours selloff makes no sense after it beat on every metric and raised guidance across the board, helped by its new Google deal and the read-through from Nvidia's earnings. Plenty of AI names trade at richer valuations with far less year-over-year growth. The next key catalyst is its investor day on October 6. x.com  x.com  x.com  x.com  x.com 

Marvell's risk/reward is no longer favorable after the stock ran three to four times from the $70s in March, when it was the most obviously undervalued chip stock. Jensen Huang's call for a $1T company is partly driven by his dislike of Broadcom's Hock Tan, and the Celestial AI angle is overhyped relative to the value it adds. A bounce is likely from here, but there is no case for adding exposure at the current price. x.com  x.com  x.com 

Marvell is positioning itself as an end-to-end AI connectivity stack, spanning custom compute, interconnect IP, optical engines, switches and telemetry. Nvidia's NVLink Fusion investment and the Celestial AI photonic fabric and XConn PCIe/CXL switching deals reinforce that role. On the chart it closed up 4.26% in a bullish engulfing pattern; the recent higher low should hold, or the long case needs reassessing, and the $245-$255 pivot likely needs a couple more retests before it is reclaimed. … Show more
