SCHELLER RICHARD H disclosed roughly $464K of recent MAZE selling across a September 2025 window, making the pattern more useful as a cadence signal than a single-trade headline.

SCHELLER RICHARD H sold about $464K of MAZE through a visible September 2025 window.

The main question is whether the cluster reads like orderly liquidity management or a more meaningful reduction in alignment.

What Happened

DateCodeSharesPriceEstimated Value
2025-09-15S20,744$22.37$464K

The visible cluster added up to about 21K shares at an average transaction price near $22.37. In practice, that makes this a useful sale-window read rather than a one-line Form 4 anecdote.

Why This Window Matters

SCHELLER RICHARD H shows up here as a director tied to Maze Therapeutics, Inc.. That matters because the market reads insider trading differently depending on whether the actor is running the business, overseeing it from the board, or controlling a large outside stake.

What matters most is not just that a trade happened. It is whether the sizing, repetition, and ownership-after pattern change how investors should read alignment.

Ownership Context

The latest visible sale line reported zero directly held shares after the transaction. That does not automatically settle the full beneficial-ownership question, but it does make the direct-position reset notable.

Signal Check

This is not proof of a full thesis change by itself. It is evidence that capital actually moved in the open market, which is why readers should compare it with the next filing rather than overreact to a single day.

What to Watch

  • MAZE trading range: whether the stock keeps finding support after the sale window.
  • Repeat cadence: whether the insider comes back with another visible sell cluster.
  • Residual ownership: whether future filings still show meaningful direct or beneficial alignment.
  • Event overlap: whether the trades lined up with earnings, guidance, or a financing event.
