$SanDisk Corp.(SNDK)$ big boys cash out

Leopold Aschenbrenner’s AI hedge fund, Situational Awareness, faced a severe July collapse after concentrating over 56% of its portfolio in SanDisk (SNDK) and Micron Technology while using heavy leverage.

📉 The Blow-Up

• Massive Concentration: SanDisk and Micron made up over half the fund.

• July Plunge: SanDisk dropped roughly 43% to 47% in July.

• Margin Pressure: Falling chip prices triggered forced liquidations and a bailout by Citadel

Optical Networking Rebounds Broadly — Can a Sector Rally Without Any News?

Optical networking rebounded hard Wednesday. Lumentum +9.59% to $919.40 led the S&P 500, with AXT +11.44%, Semtech +11.03%, Coherent about +6% and Marvell +3.61% to $229.71. Lumentum had no catalyst - no earnings, no guidance, no order, no rating change. Offered instead: the group had sold off hard, and co-packaged optics makes AXT a beneficiary. Neither explains the name that led. Corning, down 14% Monday, sat it out. The bull case is that AI data must cross the optical layer and capacity is tight. That was just as true last week, while these names fell. How much of this is demand?
