The Broadening Bottom: McLaren's Three-Thrust Wash-Out Low on the ASX

Written by Christopher Hall, AdvDipFP | Authorised Representative, AFSL 526688 | Updated July 2026

The broadening bottom — Bill McLaren's three-thrust wash-out low — is a structure that can mark the end of an ASX decline rather than a pause within an advance. Gary Glover's anecdotal observation, developed across his trading career and drawing on McLaren's work, is that after a nasty downtrend a stock can make a series of marginally lower lows, each rejected, before the trend finally turns. He pointed to Xero (ASX: XRO) as a live example of the pattern forming in his 14 July 2026 session. This note sits alongside the wider Bill McLaren corrective trend framework, and it is the mirror image of the 0-1-2-3 base of four consecutive higher lows — the two patterns turn a downtrend in opposite ways.

What Is a Broadening Bottom, or Three-Thrust Low?

Where the corrective trend describes a leading stock consolidating sideways before its next advance, the broadening bottom describes the opposite end of a move — the exhaustion of a decline. Gary Glover's anecdotal observation is that after a nasty downtrend a stock can make a low and bounce, then a marginally lower low and bounce, then a third marginally lower low — three thrusts down, each rejected — before the trend turns.

Gary illustrated the pattern in the 10 July 2026 session with Commonwealth Bank after the global financial crisis, which he recalled putting in a similar three-thrust, overlapping low near $24 before its recovery. The tell is often a final flush on heavy volume — a capitulation bar where sellers exhaust — followed by an absence of further downside. Gary's related observation is that the last, heaviest days of selling frequently arrive right at the low, as forced or panicked institutional sellers complete their exit and the selling dries up thereafter.

A broadening bottom does not make a stock an immediate buy. Like the corrective trend, it marks a structure to watch — confirmation still requires a reclaim of resistance on supporting volume before the turn is established. This is a practitioner observation drawing on Bill McLaren's work, not a formal study.

Xero (ASX: XRO): a live 2026 three-thrust low

Gary pointed to Xero (ASX: XRO) in the 14 July 2026 session as a live example of the pattern forming. After a decline of roughly 60%, Gary observed the stock had begun to overlap — bouncing, then making a marginally lower low, bouncing again, then another marginally lower low: three thrusts down, each rejected, in what he described as a sideways rather than a trending-down orientation. He read the behaviour as selling drying up — volumes were up, but the action had turned sideways rather than pushing aggressively lower.

The backdrop was poor sentiment. Negative news flow — including reports of executive share sales and a change to the way senior pay was linked to the share price — had weighed on the price and unsettled some institutional holders, the kind of capitulation environment in which a three-thrust low tends to form. Gary was explicit that the structure was not yet a trade: he wanted to see a move back up through the 50-day moving average first, and the stock had repeatedly broken above the line and fallen back without a clean trigger, weakening again on the latest news. These are dated session observations about how the pattern tends to unfold, not recommendations on any stock.

Broadening bottom vs the 0-1-2-3 base of higher lows

The broadening bottom is easy to confuse with the 0-1-2-3 base, because both appear after a heavy decline. They are mirror images: a broadening bottom makes marginally lower lows, while a 0-1-2-3 makes consecutive higher lows. In the 14 July 2026 session Gary read the two live — Xero making the lower-lows broadening bottom, and WiseTech (WTC) attempting the higher-lows 0-1-2-3 — a useful side-by-side because they call for different reads.

Feature	Broadening bottom (three-thrust low)	0-1-2-3 base
Sequence of lows	Three marginally lower lows	Four consecutive higher lows
What it shows	Sellers exhausting through deeper flushes	Buyers stepping in earlier each time
Trend state	Decelerating, not yet stopped	Downtrend already stopped
Gary's live 2026 example	Xero (XRO)	WiseTech (WTC)
Confirmation	Reclaim resistance on supporting volume	Reclaim the 50-day MA (ideally the second break)

The practical risk of confusing them is buying a stock that is still making lower lows in the belief it is making higher ones. A broadening bottom is still testing lower; a 0-1-2-3 has already turned its floor upward.

Frequently Asked Questions

What is a three-thrust low?

A three-thrust low, also called a broadening bottom, is a structure Bill McLaren described in which a declining stock makes three marginally lower lows, each followed by a bounce, before the downtrend turns. Gary Glover's anecdotal observation is that a final flush on heavy volume — a capitulation bar — often accompanies the last low, after which the selling dries up.

Does a broadening bottom mean it is time to buy?

No. A broadening bottom marks a potential end to a decline, but it is a structure to watch rather than a buy signal. Confirmation still requires the stock to reclaim resistance on supporting volume before a trader treats the turn as established.

Is Xero forming a broadening bottom?

In his 14 July 2026 session, Gary Glover observed Xero (ASX: XRO) making a three-thrust, overlapping low after a roughly 60% decline — three marginally lower lows in a sideways orientation, with volume up but selling drying up. He was explicit it was not yet a trade: he wanted to see a reclaim of the 50-day moving average first, and the stock had broken above and fallen back without a clean trigger. This is a dated session observation, not a recommendation.

How is a broadening bottom different from a 0-1-2-3 pattern?

They are mirror images. A broadening bottom makes three marginally lower lows — the downtrend is decelerating but has not yet stopped. A 0-1-2-3 base makes four consecutive higher lows — the downtrend has already stopped and the floor is rising. Both can precede a turn, but confusing them risks buying a stock that is still making lower lows in the belief it is making higher ones.
