Someone really should investigate the price action into some of these ancillary biotech stocks.....very reminiscent of a certain Situational Awareness with chip stocks earlier in the year. No one is filing ownership and yet these stocks push higher regardless of macro, or geopolitical news or the overall index moves. Someone with swaps? or options likely at play then using the momentum pf retail and algos to add to the bid. The trade is melting up perfectly to the end of the quarter (not surprised to see them even more aggressively up today than usual to mark performance). We saw this with the chips trade after an unprecedented April-June. But some of the moves with this trade exceed that euphoria (Look at $TXG, $TWST, $SDGR, $RGEN, $GRAL, and a host of other companies)........DO we see the similar move after a giant quarter with a reversal to kick of the next quarter, that was the fate with chips and caused the fund to blow up. Be interesting to see if they learned any lessons, Im guessing not based on recent performance, and if it is a different player the strategy looks the same. These companies need financing and should hit the market bid which is what set off Viacom and was the undoing of Bill Huang in 2021. Lets see, but a basket of these stocks looks interesting at current levels sometime today for gravity/secondaries to come early in Q4

No one earned this drawdown more than the growth-at-any-price bros paying >100x trailing P/E for $FICO at the 2024 high...with revenue at record levels and net margins having expanded from ~LDD% to ~30% in just six years. If you're even slightly off on any of the ambitious assumptions you must have been making around market position, pricing-driven growth, or the exit multiple, you lose A LOT of money. That said, if there’s a definition of a business worth paying up for, FICO is probably it. Or was... interpreting what the recent changes to the mortgage-scoring landscape mean is no small feat for a tourist like me.

Judging Tower Semiconductor ($TSEM) by how advanced its chip process is misses what its chips are for. Skeptics often set Tower's older 65 nm process against the more advanced processes at TSMC ($TSM). That yardstick suits logic chips, which are judged on transistor density. It does not suit the analog chips Tower makes for optics. 1. In an optical engine, the analog front-end is the circuitry that drives the laser and reads the returning light. It needs speed, linearity and power efficiency, not maximum transistor density. 2. Tower's strength is its silicon-germanium BiCMOS processes. They have long dominated the merchant market for these laser-driver and receiver chips because they deliver high performance without the most advanced CMOS logic. 3. A less noticed strength is hybrid bonding. Co-packaged optics needs an electronic chip bonded reliably onto a photonic one. Tower already runs mature, high-yield hybrid bonding for stacked image sensors in high-end phones, where a signal-processing chip is bonded onto a light-sensing chip. A close technical parallel, already at volume. The limit: if the electronic chip has to take on more complex signal processing, such as clock recovery or adaptive equalization, TSMC's advanced FinFET processes do offer real advantages in power and integration. Different foundries may end up making different parts of the system. So Tower's position in optics rests on silicon-germanium and photonic process expertise, not on advanced logic.
