EINHORN DAVID

Director Einhorn executes offsetting sale/purchase of 1,017,163 shares at $69.16; ends with 8.64M shares as stock trades near 52-week lows.

Director David Einhorn executed 2 separate sales totaling 1,017,163 shares for $70,346,993.08 paired with 1 purchase of 1,017,163 shares for $70,346,993.08—a monetarily neutral transaction at identical pricing ($69.16 per share). The timing coincides with significant price weakness: GRBK is down 17.1% from its 52-week high and down 17.1% over the past 30 days, though the stock remains above its 52-week low of $44.70. Einhorn's prior sales at this ticker (5 instances dating back to 2023) have consistently been followed by stock appreciation, with 30-day and 90-day returns ranging from +12.4% to +34.8%—none were well-timed at the 90-day mark. His post-transaction holding of 8.64M shares represents a stable long-term position despite the offsetting trades, suggesting the transaction may reflect technical or tax-related restructuring rather than a directional conviction change. The fundamental backdrop shows a low P/E of 8.81 against $523.7M quarterly revenue and $89.1M net income.

Director Einhorn sells 1,000,000 shares (1.00M) at $57.80 for $57,802,500.00 in 2 separate transactions

Director David Einhorn divested 1,000,000 shares in two separate sales on 2024-07-11, reducing his holdings by -43.4% from 2,302,690 to 1,302,690 shares. The 1.00M share sale at $57.80 occurred at a price 12.4% below the current $66.02, indicating the stock has appreciated since the transaction. His prior four sales at GRBK showed mixed timing outcomes: 3 of 4 achieved positive 90-day returns (ranging +9.0% to +31.0%), while only the 2023-09-06 sale showed a negative 90-day return (-10.9%), meaning his same-ticker sell timing has been consistently poor by the measure of capturing downside (0 of 4 well-timed). The substantial magnitude—disposing of 43.4% of holdings in a single filing day—alongside the recent strong price momentum (+15.5% in 30 days, +23.9% in 90 days) and a reasonable valuation (P/E 9.77) suggests this represents a significant portfolio action rather than a routine rebalance.
