Zak Mir takes a charting look at the USA Chartbreakers – Monday 15th September 2025

Zak Mir takes a charting look at S&P 500, Nasdaq 100, Allied Gaming, Biosig, Conifer, Entero, Envirotech, GD Culture, Hyperion, iSpecimen, Sonnet, and Wolfspeed.

In today’s chart rundown, I take a technical look at the big-picture indices (S&P 500 and Nasdaq 100) and a selection of stocks that caught my eye: Allied Gaming, BioSig, Conifer, Entero, Envirotech, GD Culture, Hyperion, Century, Sonnet and Wolfspeed. Below I walk through the key levels, indicators and my near-term targets so you know what I’m watching and why.

As always, do your own research and treat these as chart-based observations rather than hard recommendations.

Market overview: S&P 500 and Nasdaq 100

S&P 500

The S&P is still tracking toward the April price-channel top near 6,750. We remain on the right side of recent broken resistance around 6,540 — that’s constructive. Ideally we don’t see a break back below 6,500 (that was August resistance). The RSI is healthy at about 67, so not overbought yet, and price sits well above the 50-day line.

Worst case: a test of the channel floor and the 50-day line near 6,400. Best case: a turnaround or continuation up to the channel top (6,750) by the end of next month or sooner.

Nasdaq 100

The Nasdaq 100 is trading on the right side of 24,000 for the first time and is eyeing the April channel top around 24,800 by the end of this month. With the AI-led momentum it’s possible we extend as high as 26,000 by the end of next month.

Key near-term levels: recent resistance near 23,700 should act as support now; the 50-day line sits around 23,300 if we need a pullback. RSI has just broken into the low 60s — that breakdown through the mid-50s/60 area suggests a fresh leg higher is possible.

Stock picks — levels, momentum and targets

Below I summarize the charts I covered and the technical setups I’m watching. For each name I note key support/resistance, the role of moving averages or RSI, and my near-term target if the pattern resolves as hoped.

Allied Gaming

Shares have spiked up then pulled back. The critical level here is the 200-day line around $1.40. If Allied can hold above $1.40 on an end-of-day close, there’s a chance for a repeat of the earlier spike.

BioSig

BioSig has formed a rising trend channel and cleared the 50-day at roughly $5.24. Recent resistance around $5.60 has been taken, and while maintaining that is important, the chart suggests a run toward the top of the channel — approximately $9.40 by the end of next month — if momentum holds.

Conifer

Conifer is making a second attempt to reach the channel top near $1.45. The main resistance through $1.10 has been broken on a day-close basis, so above $1.10 I’m looking for a push to $1.45 over the next couple of weeks. The RSI has shown a 50-plus rebound, which historically supports further upside in this name.

Entero 

Entero has completed a turnaround and cleared short-term resistance around $2.75. With multiple RSI rebounds above neutral 50, the chart looks punchy — my upside target is the top of the channel, as high as $5.50 by the end of next month, assuming the break holds.

Envirotech

Envirotech shows a long U-shaped turnaround from earlier in the year and an uptrend in the RSI window. We’re above recent broken resistance (around $2.50) and the next meaningful hurdle is the March resistance near $3.60. If momentum continues, a move toward roughly $7.60 by the end of next month would be in play — this is a longer-dated recovery and will require work to break the 200-day line.

GD Culture 

GDC is approaching the top of its rising February channel around $9. A clear close above $9 could trigger a fresh leg toward $14 by the end of next month. The key technical caveat: we need to stay on the right side of the broken September resistance near $7.50 — holding above that level is important for the bull case.

Hyperion

Hyperion has shown a strong push through main resistance near $10. Above that level I’m looking at the top of the channel near $19 by the end of this month. If this move takes out the July resistance, the chart could reward momentum traders.

Century

Century looks a bit unloved at the moment. The immediate priority is to get an end-of-day close back above recent resistance at $0.52. If the shares can reclaim $0.52, the path to the top of the range at $0.65 becomes possible. If not, the stock is likely to remain range-bound.

Sonnet

Sonnet appears ready on a second or third attempt. The main resistance is around $4.30; above that I’m eyeing the channel top — potentially much higher by the end of October. The shares have bounced well before (notably in July), so this pattern bears watching for another successful run.

Wolfspeed

Wolfspeed presents a constructive setup: rising trend-channel base, an unfilled gap to the upside and a clear break through neckline resistance around $2. A close above that area opens a path toward roughly $4.10 by the end of next month. The RSI has shown a 50-level rebound and price is tracking the rising 50-day line — all positive technical signs.

What I’m watching and why it matters

  • Broken resistance becoming support: Many names and the indices have flipped recent resistance into support. Holding those levels on day-close is the defining difference between continuation and a false breakout.
  • RSI behavior: Rebounds above the neutral 50 level have been a consistent signal for further upside in several charts I follow. Watch for continued RSI support rather than divergences.
  • 50-day and 200-day lines: The 50-day is acting as a near-term trend guide for many names; the 200-day marks longer-term structural support or resistance. End-of-day closes relative to these moving averages tell the story.
  • Price channels: I’m trading toward the tops and bottoms of defined channels — they provide clear targets and invalidation points.

Summary

Overall the tape looks constructive: S&P and Nasdaq remain bias-heavy to the upside while several individual names are showing clean technical setups — breakouts, channel runs and RSI support. The game remains to respect proven support (broken resistance, 50/200-day lines) and manage risk around those defining levels.

I’ll keep watching these charts and will have more updates tomorrow.
