Traders pile into call options as fear of missing out grows, according to Cboe

The important read-through is not just “more call buying,” but that equity upside is increasingly being financed through short-dated convexity rather than cash equity. That tends to amplify momentum for the most liquid, high-beta names and creates a reflexive feedback loop: rising prices force dealers to chase delta, which can mechanically support indices into earnings even if fundamental revisions are mixed. The near-term beneficiaries are option market makers, exchange venues, and names with heavy call open interest where gamma can compress realized volatility and extend the tape.

For CBOE, elevated retail/speculative flow is a second-order positive because the business monetizes participation, hedging demand, and volatility turnover rather than market direction. The bigger issue is timing: this is most supportive over days to a few weeks, not months, because call intensity often peaks when sentiment is already stretched. If earnings disappoint or breadth rolls over, the unwind can be abrupt, especially in single-name tech where positioning is crowded and implied vol may be underpricing gap risk.

The contrarian risk is that investors are confusing “fear of missing out” with durable demand. Call buying can be a late-cycle signal if realized volatility fails to confirm the rally; in that case, dealers unwind less supportively and the market can transition from melt-up to air-pocket quickly. A cleaner tell is whether call activity is broad-based across sectors or concentrated in a handful of earnings names; concentration would imply a more fragile, crowded trade rather than a healthy risk-on regime.
