What Drove It

At 13:30 the EMA9 (375.1824) fell below EMA21 (376.4298) and EMA50 (376.8535), triggering a strong‑sell cross‑down for Trend-Following. The algorithm closed the original long and opened a short at $366.14, honoring its stop‑loss rule. Meanwhile, Mean‑Reversion and The Thinker saw RSI plunge to 12.88, well below the 30‑threshold, and price touch the lower Bollinger Band (371.9983), prompting strong‑buy signals that opened longs at the same price. At 15:20 another EMA cross‑down (EMA9 370.5228 < EMA21 370.6227 < EMA50 372.2457) forced Trend-Following to flip to a short at $369.99, reinforcing its bearish bias as the market slid toward $361.84 by close.

Current Standings

Trend-Following leads the pack with $100,089.50, up 0.09% from its $100,000 start. Mean‑Reversion trails at $99,283.40, down 0.72%, and The Thinker sits at $99,785.25, down 0.21%. Momentum and The Reader sit flat at $100,000. All five strategies underperform the GOOGL buy‑and‑hold benchmark, which fell to $95,123.42, a 4.88% loss since the 30‑May entry (Confirmed — COWLS Corner data).

Tomorrow's Setup

Watch the 376‑380 EMA corridor. If EMA9 crosses above EMA21, Trend-Following may flip long again. Mean‑Reversion and The Thinker must guard their trailing stops at $359.88; a breach below could lock in losses. Key data: the Fed’s June 12 policy statement could add volatility, so keep an eye on price action around $368‑$372.
