Market Snapshot — September 18, 2026 (4:00 PM ET close)
| Index | Level | Change |
|---|---|---|
| S&P 500 | 7,650.50 | +0.17% |
| NASDAQ | 26,522.55 | +0.39% |
| Dow Jones | 51,682.64 | -0.18% |
| VIX | 14.85 | -3.82% |
Friday delivered exactly the kind of session the SAR board loves to digest: a tech-led, breadth-light grind higher. The NASDAQ outpaced the S&P 500 while the Dow slipped 0.18% and the Russell 2000 lagged at -0.50% — cyclicals took the back seat while AI-linked semis carried the tape. The VIX bled another 3.82% to 14.85, closing below 15 as the post-Fed-hike jitters fully faded.
The macro backdrop softened in the bulls' favor into the weekend. Oil retreated from the $100 line after French President Macron called for a G7 meeting to release strategic reserves, and gold held firm around $4,300 support with $4,500 in focus — traders are hedging the rate-hike path without dumping risk assets. Asia did its part too: the chip-heavy KOSPI ripped +2.66% and Taiwan's TAIEX surged +2.90%, while the Nikkei gained +1.38% to 65,018.95. Europe, by contrast, was distinctly red (DAX -1.60%).
The result: four of five core semis closed green, and — more importantly for SAR watchers — the bearish wall is compressing fast. No flips today, but two bears now sit inside the 3% danger zone.

Close: $559.82 | +2.70% | Flip at $468.95 (-16.23%)
AMD was the cleanest chart on the board Friday, closing at $559.82 — essentially the session high of $559.91 — on strong volume. Its SAR support climbed from $461.78 to $468.95, and with a 16.23% buffer below price, this is the one name where the trend is doing all the work. Day 9 of the uptrend that began with the September 8 flip, and the highest close of this run. Nothing to fix here.
Close: $357.61 | +2.97% | Flip at $366.69 (+2.54%) ⚡
Broadcom bounced hard for a second straight session, and its bearish SAR wall is crumbling fast — the flip level fell from $368.66 to $366.69 while price rallied from $347.30 to $357.61. That's a compression of nearly four percentage points in one day. At +2.54% from a bullish flip, AVGO joins MU in the near-flip zone. The AI capex narrative (Crusoe's ~$4B raise, Schwab Network's Dennis Dick naming AVGO among the names fighting the sideways battle) is doing the heavy lifting. Watch $366.69 Monday.
Close: $222.27 | +1.34% | Flip at $232.75 (+4.72%)
Jensen Huang said Nvidia's chip sales could double next year, and he's attending Tuesday's Trump-Xi state dinner — but the daily chart is healing slower than the headline flow suggests. NVDA gained 1.34% and its SAR resistance eased from $233.24 to $232.75, yet the flip still demands a 4.72% rally. It's the slowest of the three bears to close the gap. Post-market, shares drifted to $221.78. Until $232.75 breaks, rallies remain counter-trend by this indicator's rules.
Close: $108.60 | -0.18% | Flip at $94.05 (-13.40%)
After Thursday's +7.7% blast on SK Hynix U.S. memory-manufacturing talks and analyst target hikes, INTC merely paused — opening at $109.80, tagging $110.49, and closing a shade lower. That's healthy digestion, not distribution. INTC is now the board's longest-tenured bull at Day 10, with its SAR support rising to $94.05 and a fat 13.40% cushion. Post-market bid nudged to $109.15.
Close: $1,015.80 | +3.92% | Flip at $1,031.55 (+1.55%) ⚡
Micron was Friday's chip leader, up 3.92% to $1,015.80 as RBC argued the market still isn't paying for its AI memory exposure, and SanDisk's 8% S&P 100-inclusion pop lifted the whole memory complex. The math is now simple: MU's bearish SAR sits at $1,031.55, just 1.55% above the close. One more green session — roughly $16 of upside — and the September 14 bearish flip is erased. Note the round-number gravity too: the flip level sits right at the $1,030+ zone. This is Monday's single most important chart on the board.
| Catalyst | Impact |
|---|---|
| Jensen Huang: Nvidia chip sales could double next year (Barron's) | NVDA +1.34% — racks, CPUs, and networking cited as the volume drivers |
| RBC: MU's valuation doesn't fully reflect AI memory demand (Invezz) | MU +3.92%, day's best chip; memory complex bid |
| SanDisk jumps 8% on S&P 100 inclusion (Invezz) | Spillover strength across memory names; MU/SNDK momentum pocket |
| Post-Fed-hike digest: yields near 5% test the rally, but AI buyers stay engaged (FXEmpire, Kitco, ETF Trends) | Nasdaq outperformed Dow; gold shrugged off the hike; financials favored |
| Oil retreats as Macron calls G7 reserve release (FXEmpire, Barron's) | Removed the week's biggest macro pressure point; Brent pulled back from $100 |
| AI infra capex keeps flowing: Crusoe ~$4B raise at ~$31B valuation; Anthropic pursues IPO (Bloomberg, NYT) | AVGO +2.97% and the AI complex held its bid despite rate pressure |
| SK Hynix U.S. memory manufacturing talks + INTC analyst target hikes (sentiment/news flow) | Fuels INTC's Day 10 bull run; dilution worries the counterweight |
| Buffett hands Berkshire chair to Howard; BMO upgrades MACOM (Reuters, Invezz) | Sentiment backdrop churned on the BRK transition; semi bounce broadened |
This was the week the board got scrambled and started reassembling. Monday's AI-pause panic produced a triple flip (NVDA, MU, AVGO all bearish); Wednesday's Fed hike froze everything; Thursday's relief rip lifted all five chips; and Friday, the bears didn't flip — they just got weaker. All three bearish SAR levels fell today (NVDA $233.24→$232.75, MU $1,034.18→$1,031.55, AVGO $368.66→$366.69) while all three prices rose. That convergence is the classic late-stage bearish setup on this indicator: the wall stops retreating upward and starts getting overrun.
The macro crosswinds haven't gone away — they've just stopped biting. The 10-year near 5% is still testing every AI-multiple in the market, and the Fed did hike this week, yet the Nasdaq outperformed the Dow and the VIX closed at 14.85. FXEmpire's read matched the tape: yields near 5% are testing the rally, but AI buyers stay engaged. Meanwhile gold holding $4,300+ and oil backing off $100 tell you the inflation-and-geopolitics corner of the trade (Iran war logistics, China restocking oil) is being hedged, not feared.
Internals say rotation, not exit. The Russell's -0.50% against a green Nasdaq is the fingerprint of a narrow, quality-led tape. Asia's chip indices — KOSPI +2.66%, TAIEX +2.90% — set an aggressive tone overnight that US semis honored at the open. ETF inflows hit a record $1.51 trillion year-to-date, and crypto reclaiming $80,000 (with the SEC easing tokenized-trading rules) rounds out a risk-appetite picture that is decidedly not risk-off.
The week ahead is thin on catalysts but heavy on positioning. MU reports late September, so its flip-or-fail at $1,031.55 doubles as a sentiment referendum on the memory trade heading into earnings. And with NVDA needing +4.72% while MU needs just +1.55%, the composition of the board could look very different by Tuesday's close.

The Parabolic SAR (Stop and Reverse) is a trend-following indicator that places dots above or below price. Dots below price = Bullish (uptrend). Dots above price = Bearish (downtrend). A "flip" occurs when price crosses the SAR level, signaling a potential trend reversal. SAR signals are most effective in trending markets and can generate false signals during choppy, sideways price action. This analysis is for educational and informational purposes only.
