SET Index: Where Are We in the Wave? Two Scenarios and the Exact Levels That Decide

Track. Study. Wait. Strike.
English อ่านภาษาไทย (Thai)

A few days ago someone asked me where SET actually sits right now in its Elliott Wave cycle.

I'll say this upfront: everything else on this page has been backtested first. This one hasn't — it's a purely subjective technical read, not a signal from any system we actually trade on. Worth being straight about that before going further.

A rule my Elliott Wave teacher gave me

One thing stuck with me from the person who taught me this method:

"Impulse waves count clean — you'll see a clear 5. Corrective waves are messy, and they're genuinely hard to count at all."

So instead of just asserting a wave count, I tested that rule against real SET price data. Not a guess.

What the data actually shows

Counting from the June 23, 2025 low (1,062.78), price traces a 5-wave impulse that's genuinely clean — it satisfies all three of Elliott's cardinal rules: Wave 2 never retraced below Wave 1's start, Wave 3 isn't the shortest of the three impulse waves, and Wave 4 (1,382.97) never overlapped Wave 1's territory (which topped at 1,323.52).

Then I went back and checked the big decline that came before this rally — the 2022–2025 drop from 1,713 down to 1,063. That one fails the cardinal rules: its Wave-4-equivalent bounce overlapped its Wave-1-equivalent zone. By the teacher's own diagnostic, that decline reads as messy — likely corrective, not a clean impulse.

A messy prior decline paired with a clean current rally is itself a piece of evidence — not proof — leaning toward the bullish read below.

The chart and the decision levels

Two scenarios, and the exact levels that decide between them

Scenario 1 — a genuine new cycle. The current Wave 5 (running since the March 2026 low of 1,382.97) tops out in the 1,644–1,674 zone, then pulls back but holds above roughly 1,450 — a shallow, healthy correction. That confirms the new uptrend and further gains are likely over the following quarters.

Scenario 2 — this was only a bounce. Tops in that same 1,644–1,674 zone, but instead of holding, reverses hard. The larger 2022–2025 downtrend was never actually finished, and price eventually threatens the old lows again.

SET levelWhat it means
1,644 – 1,674Decision zone — both scenarios expect resistance here. How price behaves after this is the real signal, not whether it gets there.
Holds above ~1,450Scenario 1 confirmed — healthy pullback, new cycle intact.
1,383 – 1,450Gray zone — deeper pullback, still technically alive, needs to show a turn.
Closes below 1,382.97First crack — Scenario 1 in real doubt.
Breaks below 1,235.30Scenario 2 becomes the higher-probability read.
Breaks below 1,062.78Scenario 1 is dead. Scenario 2 fully confirmed.

The honest caveat

Elliott Wave counting is inherently subjective — a different analyst could draw the Wave-2/4 boundaries differently, and the "messy prior decline" read used a blunt swing-detection filter, not a rigorous multi-degree count. Treat this as one input to weigh, alongside the actual distribution-day count and RS data — never a standalone signal.
