| Series | First | Latest | Min | Max |
|---|---|---|---|---|
| S&P 500 (SPY) | 100.0 | 1274.5 | 93.6 | 1274.5 |
| Fed total assets | 100.0 | 928.3 | 99.4 | 1233.1 |
Index SPY and WALCL (both monthly avg) to 100 at the shared startSPDR S&P 500 ETF (SPY, daily adjusted close, Yahoo Finance) and total Federal Reserve assets (WALCL, weekly, millions of dollars, FRED), both rebased to 100 at their shared start. Both are averaged to monthly so the lines share an axis. QE expands WALCL; a tight pairing between the lines is often read as 'liquidity-driven' equity markets, though the correlation is not causal. SPY's adjusted close reflects total return.
Finding ideas is the easy part. The hard part is turning them into trusted, deployable evidence fast enough to repeat the loop before the market moves.
