Back in September 2020, Barclays published something most retail traders never saw: a research report called "U.S. Equity Derivatives Strategy: Impact of Retail Options Trading." Think of it as Wall Street's instruction manual for how to profit off your options gambling. And guess what? That playbook is still working in 2026.
Here's what they documented: when brokers went commission-free in late 2019, retail investors flooded into short-dated, out-of-the-money call options—basically lottery tickets on stocks like Tesla and Apple. Small-lot call purchases jumped to roughly 40-45% of total customer volume. You weren't just noise anymore; you were moving the market.
But here's the part they don't tell you: that flow was predictable, and Wall Street built strategies to harvest it. The report showed retail call-buying systematically pushed short-term implied volatility higher, flattened volatility skew, and forced market makers to buy stock to stay hedged. That hedging flow was estimated to drive about 30% of total volume in the most popular names.
Barclays laid out two clear ways institutions could monetize this. First, their proprietary "VolScore" metric identified stocks where retail overpaid for volatility. The trade? Sell one-month delta-hedged straddles and collect the premium retail traders were systematically overpaying. Second, on names with strong retail interest but flatter skew, they recommended buying call spreads to participate in momentum more cheaply than retail's lottery tickets.
In plain English: Wall Street had quantified your behavior and built a machine to profit from it.
Fast forward to 2026, and nothing has changed. Options volume set new records in 2025—15.2 billion contracts, up 26% year-over-year. Average daily volume ran around 61 million contracts. Single-stock options grew 28%. Retail still makes up roughly half of total volume, and the call-buying bias is alive and well, especially in short-dated contracts.
Academic research keeps confirming the pattern. A 2025 paper titled "Losing is Optional: Retail Option Trading and Expected Announcement Volatility" showed retail investors disproportionately buy calls ahead of high-volatility events like earnings, paying premiums that often exceed what the stock actually moves. A March 2026 paper on further documented how this demand continues to shape the options market.
