Looking for optics companies like lumentum

Screening Filters

1. market_cap_category: mid, large

• Purpose: Focus on established companies rather than very small speculative names.
• Rationale: Lumentum is a sizable, publicly traded optics/photonics-related company. Mid- and large-cap stocks are more likely to be comparable in scale, liquidity, customer base, and business maturity.

2. relative_vol: min 1.5

• Purpose: Find stocks showing above-average trading activity.
• Rationale: Higher relative volume can help identify companies that are actively moving or attracting attention, which is useful when looking for peers in a dynamic technology/optics space.

3. region: US

• Purpose: Limit results to U.S.-listed companies.
• Rationale: Lumentum is a U.S.-listed stock, so this keeps the search focused on the same market and makes comparisons more straightforward for a U.S. investor.
