66 changes
ValuationRiot Platforms fell 11.20% to $13.76 following a combination of AI data-center financing concerns, analyst price-target cuts, and debt maturity pressure. Morgan Stanley lowered its price target from $43 to $35.50, while investor focus has sharpened on a $573 million bridge facility maturing December 31, 2026, amid broader sector weakness in tech and crypto-linked equities (Investing.com).

High: $26.42Low: $18.05Risk: High
64 changes
ValuationApplied Digital fell 11.01% to $18.14 intraday, reversing recent momentum. The company's stock had rebounded sharply following a blowout Q3 earnings report (per Investing.com, Apr 8, 2026) and fiscal Q2 release (Yahoo Finance, Jan 8, 2026), but no new catalyst is evident in today's move; the decline occurs absent announced company-specific news or broader market disruption flagged in available sources. Volume of 25.7M shares is 1.21x normal for this point in the session.1d ago

RiskHut 8 Corp fell 8.99% to $69.25, tracking a broad neocloud sector sell-off (Seeking Alpha, Oct. 15). The decline occurs despite analyst commentary positioning HUT as a defensive play in the sector, supported by $7.5B in non-recourse project financing and AI data center tailwinds. Volume at 0.95x normal for the intraday session.1d ago

High: $94.54Low: $84.31Risk: High
39 changes
ValuationJFrog shares fell 9.14% to $85.90, driven by a combination of sector-wide tech and AI stock selling pressure, profit-taking after the stock's rally to 52-week highs above $105, and continued insider selling via 10b5-1 plans by CEO Shlomi Ben Haim and CTO Yoav Landman, according to the web synthesis. Volume ran 2.00x elevated at nearly 3M shares 360 minutes into the session, signaling heightened institutional repositioning ahead of the November 5 earnings print.1d ago

50 changes
ValuationTwilio (TWLO) fell 13.25% to $237.16 on October 16, 2026, driven by profit-taking after a 90% year-to-date rally, pre-earnings de-risking ahead of Q3 results due October 29, and a technical break below its 50-day moving average (~$253.97) that triggered stop-loss orders, according to Barron's. Analyst concerns over stretched valuations following the stock's recent S&P 500 inclusion added selling pressure.1d ago

ValuationCerebras Systems shares fell 9.02% to $129.34 in intraday trading with volume at 1.16x the historical average for this time of session. No specific catalyst driver was identified in available reporting; the decline occurred against a backdrop of earlier positive analyst sentiment (per Investing.com articles from June and May 2026 documenting analyst initiations and prior pullbacks). The move represents a reversal from recent strength.1d ago

ValuationOkta declined 8.59% to $190.60, driven by a combination of macroeconomic pressure—hotter-than-expected inflation data renewing concerns about persistent higher interest rates—and cautious Wall Street sentiment, including fresh analyst ratings moving to Hold (Yahoo Finance). The move follows a sharp multi-month rally, leaving the stock vulnerable to profit-taking; volume surged to 2.57x the time-adjusted average, signaling elevated institutional activity.1d ago

42 changes
ValuationAurora Innovation, Inc. moved -6.20% intraday from $5.40 to $5.07. Aurora Innovation Inc. (NASDAQ: AUR) is down over 6% today due to lingering negative sentiment after Zacks Research downgraded the stock to "Strong Sell" on October 14, paired with ongoing investor caution over high cash burn, delayed profitability timelines, and heavy insider selling. ### Key Factors Pressuring AUR Stock - Analyst Downgrade: Zacks Research recently cut its rating on Aurora Innovation to a "Strong Sell", shifting near-term sentiment downward. - Financial Pressures & Cash Burn: Investors remain cautious about heavy R&D spending, wider-than-expected recent per-share losses, and a commercialization timeline that pushes gross margin breakeven out toward 2027. - Heavy Insider Selling: Continued insider share sales—including millions of dollars in stock sold by company directors over recent weeks—have added selling pressure. - Upcoming Q3 Earnings Jitters: The company is scheduled to report its third-quarter 2026 financial results and host a business review call on October 28, 2026 , causing some traders to reduce exposure ahead of the event.

High: $122.95Low: $98.69Risk: Medium
57 changes
ValuationDigitalOcean shares fell 9.87% to $98.66 following profit-taking after its Open Intelligence Summit (October 13) and a broader mid-week sell-off in high-flying infrastructure and AI-adjacent plays. The stock had surged 120–150% year-to-date before the correction, prompting institutional rebalancing despite maintained positive ratings from analysts including Citizens and KeyBanc (per investing.com and 247wallst.com). Volume of 1.85M shares was 1.41x the time-adjusted average.1d ago

71 changes
RiskApplied Optoelectronics fell 11.68% to $86.36 on October 14 amid a broad sector selloff in optical networking and AI infrastructure stocks, driven by investor anxiety over AI spending returns and profit-taking (Yahoo Finance).

16
MSTRStrategy Inc
$136.83▼ 9.56%30D: +4.47%
High: $151.29Low: $130.97Risk: High
58 changes
RiskStrategy Inc. (MSTR) fell 6.25% to $141.83 after MSCI announced new index eligibility rules that threaten to remove non-operating companies and digital asset treasury firms from its global equity indexes. Because MSTR holds a massive corporate Bitcoin reserve structured as a passive asset holder rather than a traditional operating business, it faces potential exclusion, with the final affected-company list due November 11 and index changes taking effect November 30 (Yahoo Finance, Investing.com, Benzinga). The decline diverged sharply from Bitcoin, which traded flat-to-higher around $82,000 the same day, underscoring the index-driven selling pressure rather than crypto weakness.1d ago

High: $38.75Low: $33.38Risk: High
55 changes
ValuationVIAV declined 7.63% to $34.01 as profit-taking accelerated following a 13-session, ~40% rally driven by AI data center and optical testing optimism (ng.investing.com, finance.yahoo.com). Valuation concerns and analyst re-pricing of stretched levels triggered a technical correction in the communications-equipment sector, compounded by pre-earnings positioning ahead of the fiscal Q1 2027 earnings call scheduled for November 4, 2026.1d ago

Law firms including Kaplan Fox, SBS Law, and DJS Law Group are actively recruiting shareholders ahead of a November 13, 2026 deadline, per newsfilecorp.com and gurufocus.com.

Recent Change Activity

All changes in the past 7 days

Risk
AMKR
AMKR fell 4.81% to $41.93, extending a nine-day losing streak totaling over 21% from earlier October. The decline reflects both sector-wide semiconductor weakness—triggered by Federal Reserve Chairman Kevin Warsh's remarks prioritizing price stability over near-term rate cuts, which pressured peers like Intel and Lam Research—and mounting valuation concerns ahead of Q3 earnings (per UBS downgrade cited by investing.com). Volume of 1.95M shares ran 43% below the session average for this time of day.

Valuation
RIOT
Riot Platforms fell 11.20% to $13.76 following a combination of AI data-center financing concerns, analyst price-target cuts, and debt maturity pressure. Morgan Stanley lowered its price target from $43 to $35.50, while investor focus has sharpened on a $573 million bridge facility maturing December 31, 2026, amid broader sector weakness in tech and crypto-linked equities (Investing.com). Volume at 12.4 million shares is tracking 0.77x the historical average at this point in the session.

Simultaneously, Piper Sandler downgraded ASTS from Overweight to Neutral and cut its price target from $98 to $54, citing delayed U.S. commercial service timelines now projected into H2 2027.
