US-Japan Intervene to Prop Up Yen — What's Next for US Stocks?
Today's Options Opportunity Outlook
On the macro front,$Invesco QQQ Trust (QQQ.US)$Up 0.65% pre-market,$SPDR S&P 500 ETF (SPY.US)$Up 0.5% pre-market. Divergent tech giant earnings are driving selective market positioning: Microsoft, Google, and Amazon show strong AI business performance, while Apple and Meta face pressure. The U.S. and Japan jointly intervened in currency markets for the first time in 15 years to stabilize financial conditions, supporting a 0.65% rise in the QQQ index. Options data shows QQQ’s put/call volume ratio declined to 1.08 on the previous trading day, with implied volatility (IV) at 25.35%.

On the individual stock front,$Palantir (PLTR.US)$Up 2.23% pre-market. Palantir will release its Q2 earnings after the U.S. market close on August 3. Options data shows the stock’s put/call volume ratio has risen to 0.52, with implied volatility at 70.09%. PLTR has fallen roughly 30% year-to-date, partially relieving valuation pressure, but market expectations have shifted from 'revenue growth' to 'accelerating growth.' Consensus estimates project revenue of approximately $1.81 billion (up ~81% YoY) and adjusted EPS of $0.34–$0.35. Ultimately, the stock’s direction hinges on the growth rate of U.S. commercial business and full-year guidance. The market expects U.S. commercial revenue to grow by approximately 134%; if growth falls short of this high bar—even if overall results beat expectations—the stock may struggle to sustain gains. Current options pricing implies a ±10.96% post-earnings move.

$Alibaba (BABA.US)$ Up approximately 4.2% pre-market, with Alibaba’s Hong Kong-listed shares一度 rising about 7%. The immediate catalyst is the launch of the Qwen 3.8-Max model, which Alibaba says improves reasoning, coding, agent capabilities, and multimodal performance while reducing inference costs. Market focus isn’t on short-term revenue from a single model launch, but whether lower inference costs can boost developer adoption—thereby driving Alibaba Cloud revenue growth and supporting a re-rating of its AI business.
Given the significant pre-market gap up, tonight’s key observation will be whether the stock holds above the pre-market gap after the open. If volume expands and pullbacks find solid support, bullish spreads could help reduce the cost of chasing the rally. However, if the price quickly drops below the main pre-market trading range shortly after the open, it suggests traders still view the move as sentiment-driven, significantly increasing the risk of a near-term gap fill.

Risk Warning
An option is a contract that grants the holder the right—but not the obligation—to buy or sell an underlying asset at a predetermined price on or before a specified date. Option prices are influenced by multiple factors, including the current price of the underlying asset, strike price, time to expiration, and implied volatility.
Implied volatility reflects the market’s expectation of future price fluctuations over a given period. It is derived by reverse-engineering the Black-Scholes option pricing model and is generally viewed as an indicator of market sentiment. When investors anticipate greater volatility, they may be willing to pay higher premiums for options to hedge risk, resulting in higher implied volatility.
Traders and investors use implied volatility to assess the attractiveness of option prices, identify potential mispricings, and manage risk exposure.
