Riot Platforms Surges 41% in 24 Hours Hits $800M Volume and Ranks 142nd

On October 3, 2025, Riot Platforms (RIOT) traded with a volume of $0.8 billion, representing a 41.31% increase from the previous day's activity. This placed the stock at rank 142 in terms of trading volume among all listed equities. The shares closed up 0.99% for the session, reflecting heightened market participation.

Recent market dynamics indicate growing institutional interest in the cryptocurrency mining sector. Analysts attribute the surge in trading volume to speculative positioning ahead of potential regulatory developments in the U.S. market. The stock's performance appears correlated with broader sentiment shifts in the digital asset space, as evidenced by increased open interest in related futures contracts.

Technical indicators show the stock is currently trading near key resistance levels established over the past quarter. Market participants are closely monitoring on-chain metrics for confirmation of sustained bullish momentum. Positioning data reveals a notable increase in long-term options activity, suggesting anticipation of near-term volatility.

To set up an accurate back-test I need to pin down a few implementation details that weren't specified explicitly: 1. Market universe - Should we use all U.S. listed common stocks, or a particular exchange (e.g., NYSE + Nasdaq), or another market? 2. Trading convention - Do we rank stocks on day t's trading volume, enter at the next day's open, and liquidate at that day's close (i.e., a one-day holding period)? Or do you want to enter and exit intraday on the same session? 3. Capital allocation & weighting - Equal-weight the 500 names each day, or weight by trading volume/market-cap, etc.? 4. Transaction costs/slippage - Include any round-trip commission or assumed spread? 5. Benchmark (optional) - Would you like the strategy's performance compared with a benchmark index (e.g., S&P 500)? Once I have this information I can proceed to generate the buy/sell signals and run the back-test.
