Wellchange (NASDAQ:WCT): Down 22.15% Pre-Market After Reverse Split, No Other Trigger Identified

Wellchange (NASDAQ:WCT) was indicated at USD 3.48 before the open on November 10, 2026, a fall of 22.15% against a calculated prior close of USD 4.47. A 1-for-10 reverse split affecting Class A ordinary shares, disclosed on November 5, 2026, began trading at the open on November 9, 2026 and reduced Class A shares from about 10,581,089 to about 1,058,109. Beyond the split, no catalyst turned up, and the release gave no reason. For general context, post-split trading is often choppy when a smaller float meets short sellers and momentum traders, though that is unconfirmed as a cause. Earlier figures dated October 16, 2026 put Market Value at USD 3.90 million, trailing Revenue at USD 1.35 million, cash at USD 2.81 million and Debt at USD 522,925. A quote page also lists a 1-for-5 split on September 8, 2026, which has not been independently confirmed. Given the -99.57% price change over 52 weeks, light Volume and dilution exposure, reversals look likely for Wellchange (NASDAQ:WCT).

Jin Medical International (NASDAQ:ZJYL): Down 17.7% Pre-Market, No Catalyst Identified

Jin Medical International (NASDAQ:ZJYL) was indicated at USD 3.25 before the open, down 17.7% against a calculated prior close of USD 3.95, or USD 0.70 per share. Monday's session added USD 0.59, or 17.6%, leaving the quote under the USD 3.36 close that came before it (calculated). No news dated November 9 or 10, 2026 surfaced, so no trigger was recorded. The most recent company items were wheelchair Supply for the 12th Jiangsu Provincial Games for Persons with Disabilities and a display of its rehabilitation line at four expos. For general context, lightly traded small caps frequently retrace steep single-session rallies that lack supporting news. Market value was USD 30.92 million on 7,827,355 shares at Monday's close, or about USD 25.44 million at the quote (calculated). Revenue is USD 19.73 million, a price-to-sales ratio near 1.29 at the quote (calculated). Jin Medical International (NASDAQ:ZJYL) faces wide spreads, a low float and a 52-week range of USD 1.53 to USD 5.68.

JIADE Limited (NASDAQ:JDZG): Down 14.86% Pre-Market, Driver Unknown

JIADE Limited (NASDAQ:JDZG) is indicated at USD 0.2126 before the open, down 14.86% against a calculated prior close of USD 0.2497. That prior close sits 96.2% below the USD 6.56 recorded on October 23, 2026 (calculated), a gap the review could not square with published coverage. Nothing identified explains Tuesday's decline. The company's history includes a 1-for-25 reverse split on March 23, 2026, a registered direct offering of up to USD 12.0 million priced on May 4, 2026, another USD 8.64 million that closed on June 1, 2026, and a Nasdaq halt from June 8 to July 30, 2026. As general context, reverse splits followed by offerings often weigh on prices, though that is not a confirmed cause here. Should the October 23 count of 5.43 million shares still hold, market value at USD 0.2126 would be around USD 1.15 million (calculated, unverified), compared with USD 35.63 million that day. Revenue and loss figures on the quote page are in yuan and unverified. Light trading, share sales, the minimum bid threshold and a possible Reversal all bear on JIADE Limited (NASDAQ:JDZG).

Founder Group (NASDAQ:FGL): Off 14.39% Before the Open, No Trigger Found

Founder Group (NASDAQ:FGL) was quoted at USD 1.19 before the open, down 14.39% against a calculated prior close of USD 1.39, a fall of USD 0.20 per share. Measured from USD 1.79 on October 26, 2026, the quote is 33.5% lower (calculated). Published coverage held no company release, filing or analyst note dated November 9 or 10, 2026, so no trigger shows up. Recent entries include an October 23, 2026 notice of regained compliance with Nasdaq's minimum publicly held shares rule and an August 27, 2026 announcement of a 100-for-1 share combination. For general context, stocks that have just completed a reverse split often slide as small float holders sell. The Malaysian solar builder reported 2025 revenue of 120.70 million ringgit and a loss of 7.76 million ringgit, and trailing revenue stands at USD 29.73 million, up 33.6%. Founder Group (NASDAQ:FGL) shows a published share count of 11.46 thousand and a market value of USD 20.51 thousand, which look like display errors, so no market value is stated. The float is small, spreads may be wide, and a reversal is as possible as a further decline.

Yueda Digital (NASDAQ:YDKG): Down 13.36% Pre-Market, No Trigger Identified

Yueda Digital (NASDAQ:YDKG) was quoted at USD 0.90 before the open, down 13.36% against a calculated prior close of USD 1.0388. That prior close had risen 16.7% from the USD 0.89 close on October 23, 2026 (calculated), when only 11,605 shares traded. The coverage reviewed held no company statements or analyst notes from November 9 or 10, 2026. Dated items include the November 10, 2025 one-for-one-hundred reverse split and the closing on October 16, 2025 of a USD 28 million registered direct offering. For general context, small Fintech and digital asset treasury names can slide on profit taking, dilution fears or Bitcoin swings, none confirmed here. With 5.53 million shares, calculated market value is USD 4.98 million. Revenue is USD 8.08 million, down 36.7%, against a trailing net loss of USD 86.85 million. At USD 0.90, Yueda Digital (NASDAQ:YDKG) sits USD 0.10 under the USD 1.00 Nasdaq minimum bid, and its 52-week range runs from USD 0.7307 to USD 8.869. Spreads can be wide, and dilution risk is real.

Where Things Stand

The biggest faller on Tuesday before the open is Wellchange (NASDAQ:WCT), down 22.15% on November 10, 2026. Company size, Nasdaq listings for foreign issuers, and past reverse splits or offerings link the five names. Jin Medical International (NASDAQ:ZJYL) is handing back a Monday gain. JIADE Limited (NASDAQ:JDZG) trades far beneath its October snapshot. Founder Group (NASDAQ:FGL) has no identified trigger. Yueda Digital (NASDAQ:YDKG) trades under the minimum bid. Thin names let a few trades set the price, so moves can fade at the open. This list uses a pre-market data snapshot from November 10, 2026.
