Significance 4/10

Chairman Marianne Boyd Johnson sells 100,000 BYD shares in two tranches near 52-week highs, continuing a pattern of open-market dispositions.

Marianne Boyd Johnson, Chairman of Boyd Gaming, sold approximately 100,000 shares across two transactions in early May, reducing her stake by roughly six percent. The timing is notable: the sales occurred near the company's 52-week high, before the stock pulled back over the following week. Johnson's prior Form 4 history over the past three years shows 15 open-market sales with no open-market purchases—this filing represents her 16th and 17th sales in the period, making it part of a consistent pattern of disposition rather than a tactical move. Looking at how her prior sales at Boyd Gaming specifically played out, the results are mixed: three of her five prior exits saw the stock rise afterward (poorly timed), while two saw the stock decline (well-timed exits). The company itself remains profitable with solid revenue growth, and the stock continues to trade well below its 52-week high, suggesting fundamental weakness despite the near-term sale timing. As a director and major shareholder, Johnson's continued selling without any offsetting purchases over three years may warrant monitoring for signal of reduced conviction, though the absolute share count remains substantial.

Sell
23,142 shares
$2,014,423
Significance 6/10

Director Marianne Boyd sells entire 23,142-share WAL stake for $2.0M at $87.05 blended price on 2025-12-15.

Marianne Boyd, a Director at Western Alliance Bancorporation, executed five separate sales totaling 23,142 shares for $2,014,422.94, completely liquidating her remaining shareholding in the company. The sales occurred across a narrow price range of $86.50 to $87.95, suggesting coordinated execution on a single trading day. This complete exit is a notable change in her director-level involvement and warrants review of any personal circumstances, succession planning updates, or evolving business strategy. WAL's trailing valuation metrics (P/E 10.54, annual revenue growth -31.0%) and recent 90-day stock performance (-3.0%) provide context, though the timing of a full director liquidation should be monitored against any subsequent company announcements or shifts in board composition.

Significance 5/10

Boyd Gaming Executive Chairman Marianne Boyd sold 100,000 shares at $86.62 for $8.7M on 2025-09-04.

Marianne Boyd, Executive Chairman, sold 100,000 shares for $8,662,000.00 at $86.62 on 2025-09-04, reducing holdings from 1,804,379 shares to 1,704,379 shares. The transaction occurred near the 52-week high of $87.28, with the stock at -0.9% from that peak. Boyd's cross-ticker track record shows 9 prior open-market sells with a 90-day well-timed rate of 75.00%, indicating a pattern of selling ahead of subsequent declines. At Boyd Gaming specifically, her same-ticker history is mixed: 2 of 4 measurable prior sales showed negative 90-day returns (well-timed), while the other 2 showed substantial gains afterward (poorly timed). The stock has climbed +3.8% over the past 30 days and +16.7% over 90 days, supported by fundamentals including $1.0B quarterly revenue, $151.5M net income, and a low P/E of 12.28. The timing of this sale near a 52-week high, combined with her established pattern of well-timed sells in her cross-ticker history, warrants monitoring for what may signal anticipated near-term weakness at the company level.

Significance 6/10

Boyd Gaming Executive Chairman Marianne Boyd Johnson sells 100,000 shares at $84.17; remains with 1,504,379 shares post-sale.

Marianne Boyd Johnson, Executive Chairman, sold 100,000 shares (100.0K shares) at $84.17 on 2025-08-13 for $8,417,000.00, reducing her holdings from 1,604,379 shares to 1,504,379 shares (a 6.2% reduction). The transaction occurred near Boyd Gaming's 52-week high of $86.73 with the stock currently trading at $83.95, down 3.2% from the peak. Her same-ticker history at BYD shows mixed timing outcomes: two recent sells in February 2025 posted negative 90-day returns (-2.9% and -3.7%, well-timed), while two August 2024 sales captured significant subsequent gains (+21.8% and +21.4%, poorly timed). The company's fundamentals show modest strength with annual revenue growth of 5.1%, a P/E of 11.92, and quarterly net income of $151,458,000.00 against $1,033,998,000.00 in revenue. The sale's timing near the 52-week high warrants observation alongside her prior transaction pattern at this ticker, which shows roughly even distribution between well-timed and poorly-timed sales.

Significance 6/10

Executive Chairman Johnson sells 99,800 BYD shares at $77.64–$77.68 for $7.7M; retains 1.30M shares.

Executive Chairman Marianne Boyd Johnson sold 99,800 shares across two separate transactions on 2025-02-11 and 2025-02-12 at prices of $77.68 and $77.59, totaling $7,747,982.00, while retaining 1,296,828 shares post-transaction. The sales occurred at prices near the 52-week high of $78.57 and represent a -7.1% reduction in her prior holdings of 1,396,628 shares. Her prior trades at Boyd Gaming show mixed timing outcomes: two August 2024 sales generated 90-day returns of +21.8% and +21.4% (poorly timed, as the stock rose after), while three earlier 2024 and 2023 sales saw 90-day declines ranging from -14.0% to -14.6% (well-timed). The current $78.07 stock price sits -0.6% from the 52-week high, and the stock has appreciated +7.4% over the past 30 days and +7.8% over 90 days, placing the execution near peaks in recent price momentum.

Significance 6/10

Director Marianne Boyd Johnson sells 12.5K WAL shares (63.0% of holdings) for $1.0M at $81.00

Director Marianne Boyd Johnson sold 12,516 shares at $81.00 on 2024-08-30, reducing her holdings from 19,867 to 7,351 shares—a 63.0% reduction in her stake. This substantial divestiture occurred at $81.00, near the 52-week high of $82.10, and the stock has since declined 2.7% from that high. Notably, Johnson's cross-ticker track record shows a 100.00% well-timed rate across 5 prior sells, with her sales historically followed by negative average 90-day returns of -14.3%, suggesting her sell decisions have correlated with subsequent price weakness. However, Western Alliance itself shows strong recent momentum: revenue growth of +123.6% year-over-year, a lean P/E of 11.96, and 30-day and 90-day price appreciation of +9.0% and +35.5% respectively. The combination of a large-scale director divestiture near a 52-week high, coupled with her pattern of well-timed sells, warrants closer attention to whether this signals changing views on valuation despite near-term strength in the stock and the company's rapid growth trajectory.

Significance 7/10

The fundamental picture shows reasonable valuation with a P/E of 10.82 and quarterly net income of $139,845,000.00 ($139.8M) against revenue of $967,512,000.00 ($967.5M).
