Risk-on sentiment is back with a vengeance. According to data from Goldman Sachs as of July 21, 2025, call options now account for 68% of total options market volume — a striking signal that speculative behavior has returned to Wall Street. This is the highest level since the meme stock frenzy of 2020–2021, when call volumes peaked around 72% at the height of the GameStop and AMC surge.

A Historic Shift in Market Psychology

The latest data underscores a dramatic shift in investor behavior. The market has pivoted from caution and hedging — with call ratios as low as 42% during the 2022 bear market — to aggressive bullish positioning. This renewed appetite for upside exposure suggests a collective belief in near-term gains, often detached from fundamental analysis.

The chart accompanying the Goldman Sachs report shows a pronounced rise in call-option activity beginning in early 2024 and accelerating sharply in mid-2025. Simultaneously, put option volumes have declined significantly, highlighting a sharp drop in demand for downside protection.

Opendoor: A Poster Child for Speculation

The speculative fever is evident in individual names as well. Opendoor Technologies ($OPEN) recently recorded daily trading volume equaling 298% of its market capitalization — meaning its entire float traded nearly three times in a single session. This figure is eerily close to GameStop’s all-time high of 316% on January 25, 2021, the day retail traders infamously triggered a historic short squeeze.

Such volume imbalances typically signal frothy, momentum-driven market conditions where fundamental valuations take a back seat to narrative and hype.

Behavioral Economics at Play: The Illusion of Accessibility

One cannot overlook the psychological undercurrents driving this trend. Retail traders — empowered by platforms like Robinhood, WeBull, and eToro — have grown accustomed to a “push-button profit” mentality. Social media platforms like TikTok, Reddit, and X (formerly Twitter) amplify herd behavior and promote outsized bets with minimal due diligence.

From a behavioral finance perspective, this is a textbook case of herding bias, where investors chase group behavior instead of independent analysis. Historically, such conditions have proven unsustainable, often ending in sharp corrections.

Macroeconomic Context: Liquidity, Rates, and Euphoria

Behind the surge in call activity lies a broader macro backdrop. Investors are positioning for potential Fed rate cuts by late 2025, with disinflation trends gaining momentum. As yields on short-term Treasurys fall, investors are increasingly seeking yield through riskier assets — including leveraged equity plays via options.

Moreover, the VIX volatility index remains near post-pandemic lows, making call options relatively cheap. Lower implied volatility reduces premiums, encouraging mass adoption of bullish derivatives. However, this can mask underlying fragility — particularly if sentiment shifts abruptly.

Structural Risk: When Everyone’s on the Same Side

The current setup presents classic technical fragility. When a large share of market participants are positioned on one side — long calls — market symmetry breaks down. Any adverse catalyst (e.g., earnings miss, geopolitical event, or inflation shock) can trigger a volatility shock, with cascading effects via forced liquidations and margin calls.

This scenario could result in a “volatility squeeze” that catches overleveraged traders off-guard, potentially unraveling bullish momentum within hours. The lack of hedging via puts further exacerbates downside risk.

A Market Primed for Shock from Weak Macro Data

Ironically, markets at peak optimism are often most vulnerable to disappointment. An unexpected spike in inflation, weak employment numbers, or disappointing earnings — particularly in high-multiple sectors like tech and AI — could break the current speculative wave.

The transition from euphoria to fear is often swift. As history has shown, markets don’t need a recession to correct — they just need a narrative shift and a trigger.

Is This 2021 All Over Again — or a Prelude to Something Worse?

The question investors should ask is whether this marks a return to meme-era speculation — or a warning sign of deeper systemic imbalance. With tech valuations stretched, IPO and SPAC markets heating up, and social media driving retail flows, the market resembles late-stage bullish cycles seen before major corrections.

Volatility sellers, short-dated options traders, and YOLO momentum players dominate the tape. While this could fuel short-term gains, it often ends with liquidity traps and price dislocations when sentiment reverses.

Final Take: Euphoria Has Returned — But So Has Fragility

The July 2025 call-option surge tells a clear story: the market is embracing risk again, echoing the speculative fervor of early 2021. But this time, the stakes are higher. Liquidity is thinner, macro uncertainty lingers, and retail traders have even more powerful tools to chase upside — or suffer swift losses.

For disciplined investors, this is a moment for heightened caution. The line between bullish positioning and irrational exuberance is once again being tested. As the saying goes: when everyone is on one side of the trade, it pays to ask what happens when the music stops.
