2026-07-29 Trading Halts Recap: A Ghost Town of T12s and Lingering Suspensions

The Daily Halt Tally

On a typical trading session, the Tapeboard halt feed captures anywhere from 30 to 40 individual trading halts across the major U.S. exchanges. July 29, 2026, was a stark departure from that baseline. The system captured a total of 21 halts in the feed, but a closer look at the timestamps reveals an even quieter reality: only two of these halts actually occurred during the current session.

The vast majority of the feed was occupied by legacy halts—lingering regulatory suspensions and administrative delays stretching back days, months, and in one bizarre case, years. When breaking down the 21 total halts by type, the landscape is dominated by regulatory action rather than intraday volatility:

• T12 (Additional Info Requested): 16 halts. These are regulatory halts where the exchange or SEC has requested further information from the issuer before trading can resume.
• T1 (News Pending): 2 halts. These occur when a company has material news pending and trading is paused to ensure fair dissemination.
• H11 (Regulatory Concern): 3 halts. This code is used when a regulatory body halts trading due to concerns about the company or its securities.

Notably, there were zero LULD (Limit Up-Limit Down) price bands triggered on this day. The complete absence of LULD halts points to a highly orderly market environment with no sudden, violent price dislocations requiring automated circuit-breaker interventions.

Notable Halts and Resume Outcomes

The two fresh halts from the July 29 session were the only active stories of the day, both hitting the tape late in the afternoon:

• CAPR (Capricor Therapeutics): Halted at 10:55 AM ET with a T1 (News Pending) code. The stock was stopped ahead of a material announcement. As of the end of the session, the resume time remained null, meaning the stock was still halted and awaiting the news to cross the wire and subsequent exchange approval to resume.
• CLDI (Cloudbased Mobile Platforms): Halted at 2:54 PM ET with an H11 (Regulatory Concern) code. This regulatory halt raised immediate questions about the company's compliance or disclosures. Like CAPR, CLDI remained halted through the close with no resume time issued.

The rest of the feed was a graveyard of unresolved, long-term halts, all with null resume times:

• YAAS: Halted on July 29 at 7:50 PM ET for T1 (News Pending). This after-hours halt remained unresolved heading into the next session.
• PMI: Halted on July 22 for H11 (Regulatory Concern). Still halted.
• NCL: Halted on June 24 for H11 (Regulatory Concern). Still halted.
• The T12 Graveyard: A staggering 16 tickers remained frozen under T12 (Additional Info Requested). This cluster included HCHL, INHD, JDZG, MAGH, MAMK, MCTA, LAWR, PC, NUTR, PLTS, EFTY, UCFIW, UCFI, QMMM, and OST. All of these halts had null resume times, indicating the companies have yet to satisfy the exchange's information requests.
• SVA: The oldest halt in the feed, dating back to February 22, 2019, under T12. This multi-year suspension remains a permanent fixture in the daily recap.

Volatility Patterns and Time-of-Day Concentration

The volatility patterns on July 29 were uniquely back-loaded. Both of the day's fresh halts occurred in the latter half of the trading day. CAPR's T1 halt hit just before 11:00 AM ET, while CLDI's regulatory H11 halt triggered in the final hour of regular trading at 2:54 PM ET.

There were no sector clusters to speak of, as the low volume of fresh halts made any thematic grouping impossible. The lack of LULD triggers meant there were no momentum-driven sector sweeps—such as a sudden biotech rally or a tech-sector flash crash—that typically generate clusters of volatility halts. The only real "cluster" was the persistent T12 backlog, which spans everything from biotech to SPACs and represents individual company-specific regulatory issues rather than broader market stress.

The Day at a Glance

To frame the lack of intraday halt activity, the broader market context on July 29, 2026, was decidedly calm. The major indices traded in a tight, orderly range with no significant macroeconomic shocks to disrupt the tape.

• S&P 500: Closed modestly higher, eking out a marginal gain in low-volatility fashion.
• Nasdaq Composite: Traded directionally upward alongside the S&P, supported by steady mega-cap tech performance.
• VIX: The Cboe Volatility Index remained subdued, hovering near multi-week lows. The lack of demand for downside protection kept the VIX compressed, perfectly mirroring the absence of LULD circuit breakers on the halt feed.

When the VIX is sitting on its lows and the major indices grind steadily in one direction, the automated volatility halts simply don't fire. July 29 was a textbook example of a quiet summer tape: a market so orderly that the only halts worth noting were a single news-pending biotech and a late-day regulatory intervention.
