Here are the biggest US stock market gainers at midday on Dec. 12, 2025—plus what’s driving the moves, from cannabis policy headlines to earnings reports and SEC filings. [1]
At 12:30 p.m. ET on Friday, December 12, 2025, the US stock market is showing a familiar split screen: broad indexes are lower, led by weakness in tech and semiconductors, while a handful of headline-driven pockets—especially cannabis-related names and a few earnings movers—are posting outsized gains.
On a percentage basis across US-listed stocks, many of the day’s top gainers are small-cap and micro-cap companies, where relatively modest flows (and, at times, trading halts or low liquidity) can translate into dramatic price swings. [2]
Midday market snapshot: Indexes red, “risk-on” is selective
A midday read on index performance shows a risk-off tilt, even as select stories rip higher:
- StockAnalysis’ midday index panel shows S&P 500 (-1.05%), Nasdaq 100 (-1.80%), Dow Jones (-0.41%), and Russell 2000 (-1.27%). [3]
- In ETF terms around midday, SPY is down about 0.9%, QQQ down about 1.6%, and SOXX down about 3.6%, reflecting pressure concentrated in semis/AI-linked areas.
That backdrop matters because it helps explain why the “top gainers” list is so headline- and catalyst-dependent today: in a down tape, investors tend to crowd into the clearest narratives (policy catalysts, earnings surprises, and corporate actions). [4]
Today’s top gainers (US market) as of ~12:30 p.m. ET
Below are the top percentage gainers across US-listed stocks in midday trading, with the price and % move taken from StockAnalysis’ real-time “Gainers Today” list. [5]
1) cbdMD (YCBD) — +126.6% to about $1.43
YCBD is one of the most explosive movers of the session, and the timing is notable: the rally is landing in the middle of a sector-wide cannabis surge, fueled by reports that President Donald Trump is expected to push for a major easing of federal marijuana restrictions—specifically, a move toward Schedule III classification. [6]
YCBD also had its own company-specific tailwind earlier this week: cbdMD said it regained compliance with NYSE American continued listing standards, removing a major overhang for a micro-cap name. That kind of “survival” catalyst can be powerful when momentum traders are scanning for sympathy plays during a sector pop. [7]
What to watch next: Whether cannabis headlines move from “report/rumor” to formal action—Reuters noted talk of an executive order as soon as Monday, while also quoting a White House official saying no final decisions had been made. If the policy catalyst fizzles, moves in thin names can reverse quickly. [8]
2) RYTHM, Inc. (RYM) — +108.0% to about $33.50
RYM is another high-percentage gainer at midday. Unlike the large cannabis operators, RYM’s move is harder to tie to a single, widely-circulated headline in mainstream outlets at the time of writing; this is common with small-cap, low-floatnames that can gap on momentum, positioning, or fragmented news flow. [9]
Practical takeaway: When a stock doubles intraday without an obvious broadwire catalyst, traders typically watch for halts, SEC filings, and unusual volume/borrow dynamics—and long-only investors tend to demand clearer fundamental justification before chasing. [10]
3) Oriental Culture Holding (OCG) — +95.4% to about $1.78
OCG is rebounding sharply midday—but it’s doing so in the wake of significant volatility and capital-markets news. A filing summary indicates the company entered a sales agreement for an at-the-market (ATM) offering of up to $200 million in ordinary shares with A.G.P./Alliance Global Partners. [11]
ATM programs can cut both ways: they may improve liquidity and financial flexibility, but they can also introduce dilution risk, which can amplify volatility when the stock is already moving fast.
What to watch next: Any clarification on how quickly the company intends to use the ATM, plus follow-on filings and price/volume behavior after the initial spike. [12]
4) TryHard Holdings (THH) — +54.5% to about $15.20
THH is a standout gainer by percentage, but—similar to some other micro-cap movers—there may not be one single “market-wide” headline explaining the full move in real time. Benzinga flagged THH among stocks moving higher in Friday’s session, reinforcing that it’s firmly on traders’ radar today. [13]
Risk note: Names that surge on limited or unclear catalysts can be especially prone to sharp intraday reversals.
5) Canopy Growth (CGC) — +40.7% to about $1.59
CGC is one of the clearest beneficiaries of the day’s dominant theme: cannabis-policy speculation.
Reuters reported that cannabis names jumped after the Washington Post said Trump is expected to push the government to loosen restrictions, including potential movement to Schedule III—a shift that could reshape industry economics and access to financing. [14]
6) Netcapital (NCPL) — +38.7% to about $1.47
NCPL is climbing sharply, and it has had fresh company news this week. Netcapital announced the appointment of Rich Wheeless as CEO and explicitly highlighted an intention to expand beyond traditional securities into crypto and blockchain-enabled investments. [15]
Netcapital also disclosed an inducement restricted stock award tied to performance conditions (revenue thresholds), which can draw attention—especially in a small-cap where governance, leadership changes, and incentive structures can meaningfully influence sentiment. [16]
7) Tilray Brands (TLRY) — +32.5% to about $11.17
Tilray is among the day’s most liquid, widely followed cannabis names, and it’s moving in line with the same macro catalyst: reclassification chatter tied to potential federal action.
Reuters wrote that cannabis shares jumped after the Washington Post report; it also highlighted the policy path and why the sector cares—taxes, criminal penalties, pharma distribution possibilities, and (critically) access to financing. [17]
8) Climb Bio (CLYM) — +32.4% to about $3.05
CLYM is advancing after a notable shareholder/capital-structure development: a filing summary states that Climb Bio entered into an exchange agreement with RA Capital Management. [18]
In fast-moving biotech, these types of transactions can be interpreted (rightly or wrongly) as a sign of stakeholder commitment, a tweak to ownership/overhang dynamics, or preparation for future financing flexibility.
9) Neo-Concept International (NCI) — +32.3% to about $1.64
NCI is up strongly as a micro-cap gainer. As with several names on this list, the move may be driven by momentum flows rather than a single widely syndicated headline at midday. [19]
10) Akanda (AKAN) — +32.3% to about $1.04
AKAN is another cannabis-linked name catching a sympathy bid amid the sector’s policy-driven surge. When the group moves as a basket, smaller names often show exaggerated percentage swings. [20]
11) Frequency Electronics (FEIM) — +29.7% to about $46.77
FEIM is a notable earnings-driven mover. The company released quarterly results, and coverage of the earnings snapshot reported fiscal Q2 net income of $1.8 million (18 cents per share) on revenue of $17.1 million. [21]
In a market where many investors are jittery about margins and forward profitability (especially across tech/AI supply chains), straightforward earnings catalysts can still command attention—particularly for companies exposed to specialized timing and frequency products. [22]
12) GrowGeneration (GRWG) — +28.9% to about $1.83
GRWG, which is closely watched as a picks-and-shovels-style play tied to cultivation and hydroponics demand, is moving with the broader cannabis complex as investors game out what a friendlier federal posture could mean for the overall ecosystem. [23]
13) Zedge (ZDGE) — +28.8% to about $3.13
ZDGE is popping after reporting first quarter fiscal 2026 results. A news release summary cites Q1 FY26 revenue of $7.6 million, GAAP diluted EPS of $0.06, and notes the company repurchased shares and paid its first quarterly dividend. [24]
Earnings-call coverage also circulated midday, keeping the name active and visible for momentum screens. [25]
Why cannabis stocks are dominating the gainers list today
If there’s one theme defining the US market’s top gainers at midday, it’s cannabis.
The catalyst: Schedule III reclassification headlines
Reuters reported that cannabis shares jumped after the Washington Post said President Trump is expected to push for a major easing of restrictions, including reclassifying marijuana as a Schedule III drug. Reuters added that CNBC reported (citing a source familiar with the matter) an executive order could come as soon as Monday, while also quoting a White House official saying no final decisions had been made. [26]
Why Schedule III matters to investors
Investors are focused on what a Schedule III shift could mean for:
- Lower regulatory friction and more standardized pathways for medical/pharma distribution
- Potentially lower industry taxes and improved business economics
- Better odds of institutional financing access, a longstanding bottleneck because federal restrictions have historically kept many banks and large investors on the sidelines [27]
Reuters also quoted analysts suggesting the change could set the stage for multiple follow-on catalysts (including banking reform and broader market access). [28]
Big-cap context: Lululemon surges on CEO transition and guidance
While it may not crack the overall percentage-gainers list (because its market cap is far larger), Lululemon (LULU) is one of the day’s most important headline gainers. Reuters reported the company said CEO Calvin McDonald will step down in January and that Lululemon raised its annual profit forecast, sending shares sharply higher. [29]
The Associated Press also reported details on the leadership transition timeline, interim leadership structure, and the pressures weighing on results in the Americas versus international growth. [30]
Why it matters for “top gainers” coverage: On days when mega-cap tech is pressuring indexes, a big consumer discretionary name ripping higher can signal where investors are rotating—especially when the move is tied to a credible, fundamental catalyst (leadership + forecast + capital return). [31]
Another earnings mover to watch: RH
Home-furnishings retailer RH also attracted bullish attention after earnings. Investing.com reported RH beat revenue estimates and provided updated outlook ranges, while still flagging margin pressure and tariff-related impacts. [32]
This is the kind of stock that can act as a “macro read-through” on higher-end consumer demand—though today’s broader market focus remains on cannabis headlines and the AI/semiconductor drawdown. [33]
What to watch for the rest of today’s session
Here are the key “next steps” catalysts investors are tracking into the afternoon:
- Cannabis headline confirmation (or denial): If there’s a clear update on timing and scope of any federal action, the entire cannabis tape could reprice again—either extending the rally or snapping back. [34]
- Volatility in micro-caps: Several of today’s biggest gainers (by %) are micro-caps, where spreads, halts, and low-float dynamics can dominate price action. Expect exaggerated intraday swings. [35]
- Tech/semis as the index driver: Reuters highlighted ongoing AI “bubble” anxiety after Broadcom’s results and margin commentary, pressuring chip names and the broader growth complex. If semis stabilize, indexes may recover—even if the day’s biggest gainers remain in cannabis and small-caps. [36]
