What the Session Did
On 2026-08-28, breadth came in at 1 of 20 — the weakest possible reading short of a clean sweep. The sole gainer was STX, which added +1.13% on the session and sat 83% of the way up its own 30-day range. Every other pair in the tracked universe closed lower. The median session change was -4.19%, represented almost exactly by XLM, which fell -4.19% and sat just 39% up its 30-day range.
The weakest pair was FET at -8.71%, sitting 47% up its 30-day range despite the session loss — a reminder that a bad day does not automatically place a pair at a multi-week low. The steepest losses were concentrated in the lower end of the 30-day range-position column: APT closed at just 12% of its 30-day range, OP at 22%. Pairs nearer the top of their ranges — ETH at 83%, BTC at 81%, SOL at 84% — still fell, but by comparatively smaller amounts (-2.74%, -3.03%, and -4.61% respectively).
Dispersion, measured as the gap between the strongest and weakest session return, was 9.84 percentage points (STX at +1.13% minus FET at -8.71%). That is a wide spread for a session where almost everything moved in the same direction, driven largely by the severity of the FET decline rather than by genuine divergence in outcomes across the field.

Regime Description: Broad-Decline
A broad-decline label is applied when the overwhelming majority of pairs close lower and the median session change is negative by a meaningful margin. On 2026-08-28, both conditions were met: 19 of 20 pairs fell, and the median was -4.19%. This distinguishes the session from a mixed regime, where advancing and declining pairs are more evenly split, and from a compressed regime, where moves on both sides are small enough that the direction of the median matters less than its magnitude.
The broad-decline label also differs from dispersed. A dispersed session produces large moves but in divergent directions, so breadth is not lopsided. Here, dispersion was elevated at 9.84 percentage points, but that figure was pulled by a single outlier on the downside. The underlying character of the session was directional rather than divergent: the field moved together, and the outlier was a degree-of-loss outlier, not a direction outlier.
Range positions add texture. Several pairs — STX, IMX, ETH, BTC, SOL — still sat in the upper half of their 30-day ranges despite the session loss, reflecting that the 30-day window includes prior gains. Others — APT at 12%, OP at 22%, DOT at 40% — sat near the floor of their recent ranges, indicating the session loss compounded an already weak 30-day trajectory.
Execution Cost in This Kind of Session
When a session produces a median move of -4.19% and the weakest pair falls -8.71%, the absolute size of moves is large relative to the round-trip fee floor on most retail spot venues. Coinbase Exchange publishes a tiered maker-taker fee schedule; at the lowest volume tier, the taker fee is 0.60% per side, producing a round-trip floor of approximately 1.20% before spread and slippage. Against a median session change of -4.19%, that fee floor represents roughly 29 basis points of the move — not negligible, but not dominant either.
The more relevant cost consideration in a broad-decline session is slippage. When selling pressure is widespread and sustained, bid-ask spreads on thinner pairs tend to widen. A pair that printed a -8.71% session close may have seen intraday spreads materially wider than its resting-market average, meaning that a round-trip executed during the session would have faced a higher effective cost than the published fee schedule alone implies. The session candle records only the open and close; it does not capture intraday spread behaviour.
For strategies that clear the round-trip cost through holding period rather than frequency or size — that is, strategies that hold a position across multiple sessions — a single session's move of this magnitude is a larger-than-typical cost event. For strategies that clear through frequency, the same session represents a series of smaller round-trips, each of which must independently clear the ~1.20% floor.
What One Session Does Not Establish
A single session is a sample of one. The broad-decline classification describes what happened on 2026-08-28; it carries no predictive weight about the session that follows. Regimes can persist, reverse, or fragment — the label is a description of a closed period, not a signal about an open one.
The dispersion figure of 9.84 percentage points is worth treating carefully. Because it is computed as the distance between the single best and single worst performer, it is sensitive to outliers on either tail. FET's -8.71% session loss accounts for most of the spread. Remove that pair and the dispersion picture changes substantially. A single-session dispersion reading is therefore a weak basis for any inference about how differentiated the market is as a structural matter.
Range positions describe where each pair's close sat relative to its own 30-day high and low as of this session. They do not indicate where the range will be tomorrow. A pair sitting at 12% of its 30-day range (APT) is near its recent low by that measure; it is not established by this data that it is near any forward-looking floor. The 30-day window itself will shift with each subsequent session, changing every range-position reading even if prices do not move.
The regime label, the breadth count, the median, and the dispersion figure are all backward-looking summaries. They describe the structure of a session that has already closed.
The 2026-08-28 session closed with 19 of 20 pairs lower, a median decline of -4.19%, and a single outlier — STX at +1.13% — accounting for the only green reading in the breadth count.
