In the recently concluded month of June, the US stock market exhibited an extremely fragmented "frenzy." On the one hand, macro funds were extremely fearful of missing out, with the SPY's single-month net inflow surging to a staggering $15.85 billion, nearly triple the size of May's inflow. On the other hand, the valuations of micro-level giants were pushed to extremes, with Tesla taking a commanding lead at a P/E ratio of 386.12x. $Tesla Motors(TSLA)$ $Tradr 2X Short TSLA Daily ETF(TSLQ)$ $ProShares Ultra TSLA ETF(TSLI)$ $SPDR S&P 500 ETF Trust(SPY)$
Nvidia Moves Optics Into the Package — Marvell +5.5%, Who Gets Left Behind?
Optics was Monday's theme: AXT +17.55%, Marvell +5.54%, Applied Optoelectronics +3.07%, HTGD +1.75%. Nvidia said its CPO-based Spectrum-X Photonics switch is in mass production, claiming 5x network power efficiency and 10x mean time between failures versus pluggable optics — CPO moving from validation to deployment, repricing everything from lasers to switch chips. The catch: CPO at scale takes share from pluggable modules, so the chain splits. Coherent beat and raised, then fell 7.99% the next day. HTGD reports interim results Friday. AXT, Marvell, AAOI, or HTGD?
