. 19, 2025, , ranking 387th in market activity. The move followed a strategic shift in its cloud mining operations and updated guidance on operational efficiency. Analysts noted the stock's performance aligned with recent adjustments in its infrastructure cost management framework.

Recent developments highlighted Cipher's restructuring of its mining rig utilization model, which aims to optimize energy consumption ratios.

These operational adjustments have drawn investor attention to its potential to stabilize cash flow generation amid fluctuating energy prices.

To conduct a rigorous back-test of Cipher's performance, several parameters require confirmation: 1) Whether to scan the full U.S. equity universe or a subset like the S&P 500; 2) Execution timing preferences between close-to-close or close-to-open trades; 3) Portfolio construction methods for equal-weighted positions; and 4) Platform limitations necessitating external simulation for multi-asset portfolios. These considerations will shape the accuracy of the back-testing results. The process will involve generating synthetic P&L series externally before integrating them into the testing engine for performance evaluation.
