Optical component makers like Coherent and Lumentum dropped around 10% in a single day on fears that the AI spending boom is a bubble. But right as that panic hit, Meta and BlackRock locked in a fresh $14 billion deal for a new AI data center campus in Te

Verdict: compelling thesis, but wait for the downtrend to actually exhaust

The idea argues that a roughly 10% single-day drop across Coherent, Lumentum, and Applied Optoelectronics — driven by AI-bubble fears even as Meta and BlackRock committed $14 billion to AI data center infrastructure — represents a classic price-versus-reality disconnect, and the backtest supports the mechanical case: AAOI delivered a 194% return over 60 months with a 75% win rate across 8 trades, improving to 276% with a perfect 100% win rate over the most recent 24-month subset. Revenue growth is genuinely staggering, with Lumentum up 388% year-over-year and AAOI up 82.8%, both in the top decile of Information Technology peers. But two of three names are deeply unprofitable — AAOI carries a negative 12.0% operating margin with $353.6 million in free cash flow burn landing in the 2nd percentile of its sector, and Lumentum's negative 10.9% operating margin is paired with a 2.26 debt-to-equity ratio that leaves the least financial flexibility if AI capex slows. The strategy is not triggering yet: ADX readings of 38.9 (AAOI), 46.7 (COHR), and 33.4 (LITE) all sit well above the 25 exhaustion threshold the entry rules require, and no robust parameter setup was established to fine-tune the approach. This is a setup worth monitoring closely — especially the AAOI support-bounce at $88.00 — but the downtrend is still accelerating, not exhausting. **Conviction Breakdown** - **Thesis support (68):** The demand narrative is real and backed by $14 billion in fresh capital commitments plus top-decile revenue growth, but the thesis conflates a demand signal with guaranteed order flow to these specific suppliers. - **Trade readiness (22):** None of the primary entry conditions are fully met; ADX remains far above 25 across all three names and the EMA crossover has not occurred, though AAOI sits directly on its $88.00 support-bounce trigger. - **Risk quality (35):** The 2.5% stop against stocks that just swung 10% in a session creates a razor-thin margin, the 26% maximum drawdown is sobering, and Lumentum's leverage compounds the downside if AI spending disappoints. - **Backtest evidence (70):** The 194% return with a 75% win rate over 60 months and a stronger 24-month subset are compelling, though exit fills are approximate and only 8 trades is a thin sample. - **Fundamentals trend (55):** Revenue growth and gross margin recovery are directionally positive, but two of three names have deeply negative operating margins and worsening free cash flow — these companies are spending heavily to scale and cannot easily absorb a demand shortfall.

The thesis is that AI-driven demand for optical components is structural, and the panic selloff has created a price disconnect. The strategy is designed to buy that dip systematically, but it is **not triggering yet**. Two of the four primary entry conditions are met across the board: price is below the 20-day EMA, and RSI is below 40. However, the setup requires all four conditions to align. The 20-day EMA needs to cross above the 9-day EMA, and ADX needs to be below 25 to confirm the downtrend is exhausting. Right now, that crossover has not occurred, and ADX remains elevated. For AAOI, the last close is $88.14, sitting below the 20-day EMA of $106.64. RSI is at 29.0, well below the 40 threshold, but ADX is at 38.9 — the entry rule requires it at or below 25, so it needs to drop roughly 14 points. The EMA crossover is also not close: the 20-day EMA would need to fall by roughly $9.60 to reach the 9-day EMA at $97.05. COHR and LITE tell the same story: deeply oversold on RSI (23.2 and 28.4 respectively) but with ADX readings of 46.7 and 33.4 that reflect strong, ongoing downtrends rather than the exhaustion the strategy waits for. The invalidation level is a 2.5% stop loss, and the first take-profit target is a 5.0% gain, producing an effective reward-to-risk ratio of roughly 2:1. "Wait" means exactly this: monitor for the ADX to compress below 25 and for the 20-day EMA to cross above the 9-day EMA while price remains below the 20-day EMA. The strategy captured this pattern effectively in backtesting — the AAOI configuration produced a 193.6% return over 60 months with a 75% win rate across 8 trades, though it endured a 26.0% maximum drawdown along the way. No robust parameter setup was established, as the sensitivity evaluation exceeded its time budget without returning a recommendation. The secondary support-bounce entry rules offer a more immediate possibility. These trigger when the daily low touches the nearest support level and the close finishes above it. AAOI's nearest support is $88.00, and it closed at $88.14 today — effectively sitting on the trigger. If the next session trades down to $88.00 and closes above it, the support-bounce entry…
