THE 7 LAYERS OF PHOTONICS 7. Networking (connectivity layer) $CRDO, $MRVL, $AVGO, $ANET, $CIEN The Connectivity Layer is the "Command Center" of AI compute! $AVGO and $MRVL remain untouchable in 2026, holding total pricing power through their CPO leadership. Keep a close eye on $CRDO—their 1.6T Active Electrical Cables (AEC) just hit massive volume delivery this month. As $ANET migrates the world’s largest clusters to 1.6T, who captures the lion's share of the Hyperscaler spend? In the era of "All-Optical" networking, are you betting on the steady dominance of $AVGO or the high-growth trajectory of $MRVL? Let’s hear your picks!

Photonics is a must in your portfolio Here are the top 10 that I like: (6-10) 6) $MRVL - Data center chips 7) $AXTI - Photonics materials 8) $CIEN - Optical networking gear 9) $SIVE - Precision timing chips 10) $CRDO - High speed connectivity This lineup completes the AI compute puzzle! $MRVL’s move into Photonic Fabric tech is a massive 2026 milestone, effectively breaking the power wall in chip connectivity. Meanwhile, $CRDO just crushed its revenue guidance, proving that demand for high-speed AECs and 1.6T connectors is in a structural breakout. Keep a close eye on $AXTI—as an InP material leader, they are the literal foundation for AI photonics, with capacity doubling underway to meet Tier-1 demand. In the era of "Silicon Photonics," who’s your winner: the material powerhouse $AXTI or the interconnect king $MRVL? Let’s fight it out in the comments!

Optic names pulling back today: $AAOI, $COHR, $CIEN, $KEYS, etc. 🔻 For now, they’re holding the 9/21 EMA, which is key. As long as these moving averages hold, there’s no need to panic. 📉 But here’s the red flag: If we see a loss of those EMAs with 1x average volume or more, that's when we’ll need to start worrying. 🚨 Stay vigilant, but for now, it's all about watching those key levels! 👀 👉If this helps, tap @backtesttrend

Photonics isn’t a side story anymore — it’s becoming the backbone of the AI buildout. Compute gets the headlines, but bandwidth is the bottleneck. That’s where this entire stack comes in. Watching the full chain light up: $GLW (fiber + infra), $MRVL (optical DSP + custom silicon), $CRDO (signal integrity), $AEHR (burn-in/testing), $CIEN (transport), ALAB (connectivity), FN (manufacturing), AAOI (transceivers), LITE (lasers), COHR (materials/components), AVGO (networking + ASICs). This isn’t one stock — it’s an ecosystem trade. Capital rotates into what enables scale. AI needs faster, denser, lower-latency data movement — photonics solves that. Not everything here will win equally, but the theme is gaining momentum. Watching for breakouts, volume, and continuation. When infrastructure phases kick in, moves can get crowded fast. Stay early or stay chasing. Curious about the full approach?👉 Check the @MeanReverter_

$CIEN (long) Entered around $360 on March 17, 2026 during that intraday digestion phase—looked messy at the time, classic shakeout area. Fast forward one month, now trading above $500. That’s a clean trend expansion. This is the type of name that doesn’t grind—it re-prices fast once momentum kicks in. Nothing fancy here: strong structure + right entry = let price do the validation. Still holding. No top-picking, just riding the trend as long as structure stays intact. 👉If this helps, tap @backtesttrend

Been digging into recent S&P 500 additions… honestly, it’s a bit concerning. These names are where massive passive flows (pensions, index funds) get funneled — yet the quality and valuation are all over the place. In many cases, companies get added right when they’re already stretched. That’s not exactly ideal timing. Names like $CVNA, $CIEN, $SATS highlight the issue: some have unstable fundamentals, some rely heavily on narrative, others already priced for perfection. When liquidity tightens, these tend to unwind harder than core index leaders. My takeaway is simple: Inclusion ≠ quality Inclusion ≠ good entry If anything, index inclusion can often mark a distribution phase rather than an opportunity. Out of recent adds: Maybe 1 in 5 worth a serious look Factor in valuation → closer to 1 in 10 Index going up doesn’t mean everything inside is worth owning. Passive buying doesn’t mean smart buying. 👉If this helps, tap @backtesttrend

TRADER INSIGHT: Ever try holding a beach ball underwater? It’s a perfect analogy for strong stocks when the market opens weak. I’m watching for stocks that hold their ground when everything else is falling apart. The first 30 minutes after the open is critical. While names like $LITE, $CIEN, and $TSEM were cracking under pressure today, $MU and $CRWV stood out. They weren’t breaking, they were absorbing the pressure and holding structure. When the broader market found its footing, these two names exploded into new highs. Why? Because when a stock refuses to crack under pressure, it’s a sign of hidden demand. The market punishes the weak first, but the strong rip when buyers return. I don’t wait for a stock to start flying—I want to catch the ones that should fly once the market stabilizes. This is the nuance that separates the pros from the rest. Keep your eyes on the beach balls. Curious about the full approach?👉 Check the @MeanReverter_
