I’m thinking of trading same day expiry contracts of spy

``` The deep research logic is organized as follows: Okay, let's tackle this question. The user is interested in trading same-day expiry contracts of SPY. First, I need to understand what same-day expiry contracts are. From the references, I see that 0DTE options expire on the same day they're traded. SPY options are among those that offer 0DTE contracts. The user's profile mentions they're into growth stocks, tech, and have a short-term horizon. So, they're probably looking for high volatility and quick trades. Let me check the data provided. Looking at the references, there's a query about SPY's same-day expiry contract on 2025-08-10. The results show 0 results found, but there's another query with pre-market percentage change. The pre-market change on 2025-08-08 was 0.3%, and on 2025-08-10, the pre-market change was also 0.3%. The closing price on 2025-08-10 was $637.18 with a 0.78% change. Also, there's a mention of GMXSOL launching a perpetual contract for SPY on Solana, which is a decentralized exchange. That's interesting because it introduces another layer of liquidity and possibly different trading dynamics. The user is focused on same-day contracts, so I need to explain the mechanics. From the references, 0DTE options for SPY expire at 4:00 PM EST and are cash-settled. The settlement price is the closing price of SPY at 4:00 PM. However, there's a note that some options might still trade after 4:00 PM, which could affect the final price. Liquidity is a concern. The trading volume for SPY on 2025-08-08 was 64.05 million shares, which is high. But same-day contracts might have lower liquidity compared to regular options. The user should be cautious about slippage and wide bid-ask spreads. Implied volatility is another factor. The volatility on 2025-08-08 was 1.13%, which seems low. However, same-day contracts might have higher IV due to the short time frame. The user should check the IV rank to see if it's attractive. Market impact from news is crucial. The user is interested in tech stocks, so any news related to the S&P 500, especially tech-heavy components, could affect SPY. Recent news mentions CVS Health's earnings beat and Palantir's guidance upgrade, which are part of the S&P 500. Also, the tariff announcement and Fed nominations mentioned in the market recap could influence SPY's price. The user's strategy is growth-oriented, so they might look for setups where SPY is undervalued relative to its components. The 10 stocks contributing 80% of S&P 500 gains include tech names like Apple and Palantir. If these stocks are expected to move, SPY could follow. Risks include high volatility, potential for rapid price swings, and the need for constant monitoring. The user should have a clear exit strategy and consider using stop-loss orders. Also, the impact of after-hours trading on SPY's price could affect the option's settlement. Putting it all together, the answer should outline the mechanics of same-day contracts, assess liquidity and volatility, discuss market factors, and highlight risks. The user needs a structured approach with clear sections, using tables for data and visualizations where possible. Make sure to cite the references correctly and keep the language engaging but professional. ``` ### 🎯 **Conclusion** The SPY same-day expiry contracts (0DTE) present a high-risk, high-reward opportunity for short-term traders, but they require meticulous execution and awareness of market dynamics.
