S&P 500: Decision Point Between Wave 5 Extension or Larger Degree Reset

The S&P 500 continues to press higher in a structure that is becoming increasingly critical from an Elliott Wave perspective. From the 6316 low, the index has clearly advanced in what counts best as a completed three-wave impulse into 7147, followed by a controlled pullback that fits the profile of a Wave 4 correction. The structure remains constructive, but the next move will determine whether the market is finishing a cycle—or just getting started on a much larger expansion.

Let’s break it down.

The rally from 6316 to 7147 forms a clean impulsive sequence. Momentum, breadth, and price behavior all supported the interpretation of a strong Wave 3 completion into that high. The subsequent pullback did not violate key structural levels and maintained the integrity of the uptrend, suggesting it is corrective rather than the start of a deeper reversal.

Assuming this is indeed a Wave 4, the next move higher would be the final Wave 5 of this sequence. Using standard Fibonacci relationships, we can project reasonable upside targets.

A common relationship is when Wave 5 equals 0.618 times the net distance of Wave 1 through Wave 3. Applying that here:

This aligns with a moderate extension scenario and represents a logical technical completion point for the current cycle.

Alternatively, if Wave 5 equals Wave 1, another classic relationship, the target comes in lower around 7350. This would indicate a more conservative final push, potentially driven by weakening momentum or negative divergence—something traders should watch closely if price approaches that zone.

However, there’s a more aggressive scenario on the table—and it shouldn’t be ignored.

If the recent pullback was not a Wave 4, but instead a Wave 2 of a larger degree, then the current rally is not a finishing move—it’s the beginning of a powerful Wave 3 extension. This interpretation is gaining credibility given similar behavior observed in the Dow Jones Industrial Average, which has shown signs of resetting its structure and launching into a new impulsive phase.

In this bullish scenario, a standard 1.618 extension of Wave 1 would project significantly higher targets:

That’s not just a marginal breakout—that’s a full expansion move consistent with institutional accumulation and broad participation.

So what’s the takeaway?

The market is at a fork in the road. The 7350–7560 zone represents a logical completion area for a standard five-wave sequence. If the market begins to stall, show divergence, or fail to hold higher lows in that region, it would support the idea that a larger correction is due.

But if price slices through that zone with strength—especially on expanding volume and momentum—then the probability shifts heavily toward the extended Wave 3 scenario, opening the door to much higher levels into the 8300+ region.

SNDK: Post-Earnings Surge Ignites Wave 3 Expansion

The structure in SanDisk Corporation is even more explosive—and much clearer.

We have a well-defined setup:

This correction was shallow and held well above key retracement levels, signaling strong underlying demand. That set the stage for a powerful Wave 3, which is now unfolding in dramatic fashion.

Using standard Fibonacci extensions:

Initially, there was a question of whether the stock might instead be completing a smaller-degree move—specifically a Wave 5, which would have capped upside near 1125 using a 0.618 relationship.

But the market answered that question decisively.

Following the latest earnings report, buyers stepped in aggressively, pushing SNDK above 1125, invalidating the weaker Wave 5 scenario and confirming that a larger impulsive Wave 3 is underway.

Momentum didn’t just hold—it accelerated.

As of 10:30 PM PT, the stock is trading around 1231 in pre-market, up another 48 points, signaling continued institutional demand and strong follow-through.

This kind of behavior is textbook Wave 3 price action:

From a trading perspective, this is the phase where dips tend to be shallow and quickly bought. Trying to short this type of move without clear reversal signals is extremely high risk.

The key level now becomes sustained structure above 1125. As long as price holds above that breakout zone, the path of least resistance remains higher toward the 1532 target.

Final Thoughts

Both the S&P 500 and SNDK are at pivotal inflection points—but in different ways.

This is where Elliott Wave analysis shines: not in predicting certainty, but in mapping probabilities and recognizing when the market confirms one path over another.

Right now, momentum is favoring the upside—but the next few sessions will be critical in determining just how far this move can go.
