Markets as Coupling Systems

A market is not a place. A market is a coupling system: a set of agents connected by transaction pathways, exchanging coupling capacity under constraint.

Efficient market hypothesis. Says prices reflect all available information. The axioms say: prices reflect all available records. Records are incomplete, biased, and subject to adversarial manipulation. Markets are efficient at processing the records they have.

They are not efficient at producing accurate records. The distinction is critical: a market that efficiently processes false records will produce efficiently false prices. The 2008 crash was not a failure of market efficiency.

It was a triumph of market efficiency — the market efficiently priced instruments based on fraudulent records.

Bull and bear markets. Accumulations of directional records. A bull market is a sequence of transactions that each reference prior rising prices — a record cascade. Each new record reinforces the distribution.

The distribution narrows around upward momentum. This is not irrational exuberance. It is record-driven probability collapse. The cascade continues until the accumulated records diverge from underlying coupling capacity (the actual productive output of the economy).

At that point, the Ledger corrects. The cascade reverses. Bull becomes bear. The audit executes.
