Tuesday, June 23 delivered a sharp technical breakdown in US equities, led by a devastating selloff in semiconductor stocks. The PHLX Semiconductor Index (SOX) cratered roughly 7%, the worst single-day drop since the June 5 rout that erased over $1 trillion in market value.
The Nasdaq Composite leads the declines with a 2% loss, trading around 25,622–25,649. The S&P 500 is down 1.3% at approximately 7,375, while the Dow Jones Industrial Average shows relative resilience, losing 0.74% to sit near 51,332.
Tech analysis: Key levels in play
The S&P 500 is now trading below every major moving average, from the 5-day through the 200-day. The daily pivot sits at 7,405, with first resistance (R1) at 7,416. On the downside, the classic pivot support levels cluster at 7,386 (S1), 7,375 (S2), and 7,356 (S3). A break below S3 opens a path toward 7,200 and eventually 7,000.
The RSI(14) has plunged to approximately 30.7, technically oversold territory, which could signal a near-term bounce. However, the MACD remains deeply negative, and momentum indicators continue flashing sell signals.
The Dow holds up better, trading near its pivot of 51,716 with the 200-day moving average providing a safety net at 50,829. Short-term signals are mixed-to-bearish, but the long-term structure remains constructive as long as the Dow stays above 50,800.
Chip stocks: The carnage
Micron (MU) is the hardest hit among large-cap semiconductors, plunging 10–13% to the $1,055–$1,080 range. The selloff comes ahead of its fiscal Q3 earnings report, with anxiety about memory demand intensifying. Qualcomm (QCOM) drops 6–9% to around $202–$207, pressured by both the sector-wide selloff and reports of advanced talks to acquire AI software firm Modular in a ~$4 billion deal.
AMD sheds 5–7% to $519–$520, while Nvidia (NVDA) declines roughly 3% to $202, reflecting the broader rotation away from crowded AI trades. Tesla (TSLA) falls about 5% to $383–$385. Apple (AAPL) stands out as a rare bright spot, gaining 0.5–0.8% near $299–$300.
VIX: The fear gauge wakes up
The CBOE Volatility Index spiked more than 8% intraday, climbing from a prior close of 17.28 to trade in the 18.6–20.5 range. The VIX has broken above its recent congestion zone near 16–17 and is testing the psychologically significant 20 level. Historically, sustained VIX readings above 19–20 coincide with periods of elevated equity market stress.
Market breadth deteriorates
Declining issues outnumbered advancers 2.12-to-1 on the NYSE and 1.65-to-1 on the Nasdaq, confirming that the selloff is broad rather than concentrated in a few names. The advance-decline ratios of 0.47 and 0.61 respectively reflect genuine distribution day behavior.
What to watch
The 7,356–7,375 zone on the S&P 500 is the immediate battleground. Bulls need to defend this area to prevent a deeper slide toward 7,200. The VIX trajectory will be critical, a spike above 20 with sustained volume could signal that this correction has further to run. Micron's earnings loom as the next catalyst for the semiconductor sector, with the market looking for clarity on memory demand and AI infrastructure spending trends.
For now, the technical picture favors caution. Oversold conditions could produce a bounce, but the onus is on the bulls to reclaim the moving averages before the medium-term uptrend can be considered intact.
