GeneDx Holdings Corp. (Nasdaq: WGS) stock pulled back sharply on Tuesday, Dec. 16, 2025, with shares trading down roughly 7% intraday near $140 after a prior close around $150.6. The day’s move featured a wide trading range (roughly $138.9 to $150.4)—a reminder that WGS has become one of the market’s more volatile “high-expectations” healthcare growth names. [1]
So what changed today—and what hasn’t changed? The short version: the tape got jumpy, forecasts stayed optimistic (mostly), and the debate around valuation vs. growth is still the main event.
What happened to GeneDx stock today (Dec. 16, 2025)?
By early afternoon New York time, WGS was trading around $140, down about 6.9% on the session, after opening near $149 and briefly trading above $150 before sliding to the high $130s. [2]
A widely circulated market note described the drop as an intraday decline of about 6.4% to roughly $141, adding that trading volume was running below the stock’s typical daily average—often a sign that a move may be driven by momentum positioning and profit-taking rather than a single, definitive headline. [3]
It’s also worth noting the broader backdrop: U.S. stocks were generally under pressure Tuesday amid macro-driven risk-off trading tied to fresh economic data. In that kind of session, richly valued growth stocks often feel the turbulence first. [4]
Context check: earlier in December, WGS printed prices in the $160–$170 zone before the current pullback. [5]
The latest GeneDx headlines investors are reacting to
Even when a stock sells off “without news,” investors usually aren’t trading in a vacuum. Here are the most current headlines and themes in circulation as of Dec. 16, 2025:
1) Research spotlight: GUARDIAN newborn genomic screening gets high-profile recognition
On Dec. 15, 2025, GeneDx announced that JAMA recognized its GUARDIAN newborn genomic screening study in the journal’s annual “Research of the Year” roundup—an attention-grabbing signal for GeneDx’s positioning in population-scale genomic screening and clinical utility messaging. [6]
This isn’t a “next-quarter revenue flips overnight” headline, but it can matter because (1) payer coverage and clinical adoption in genetic testing are deeply influenced by published evidence, and (2) newborn screening is one of the narratives investors most associate with GeneDx’s longer runway.
2) Analyst activity is still driving the conversation (and it’s not subtle)
Over the past several days, multiple research notes and aggregators highlighted shifting targets:
- One report said BTIG raised its price target to $200 (from $165) while maintaining a Buy view. [7]
- Another item reported Canaccord lifted its target to $160 (from $155) and kept a Buy rating, citing continued execution and growth outlook. [8]
- A separate institutional/analyst summary noted Wells Fargo maintained an Equal Weight stance while lifting its target to $155 (from $140). [9]
When a stock has already had a monster run, analyst target changes can cut both ways: upgrades fuel the bull case, but they also remind the market that a lot of “good news” may already be priced in.
3) Insider transactions: “sell-to-cover” activity is back on the radar
Recent Form 4-related coverage pointed to insider selling tied to tax withholding obligations connected to RSU vesting (“sell to cover”), which is typically treated differently than discretionary selling—though headline scanners don’t always make that distinction. [10]
What the company’s last results said (and why they still matter today)
The most concrete “anchor” for WGS right now remains the company’s most recent reported fundamentals and guidance.
In its third-quarter 2025 update, GeneDx reported:
- Revenue of $116.7 million (up 52% year-over-year)
- Exome and genome test revenue of $98.9 million (up 65% year-over-year)
- Exome/genome volume of 25,702 (up 18% year-over-year)
- Exome/genome average selling price of $3,847 (up 40% year-over-year)
- Adjusted gross margin of 74%
- Adjusted net income of $14.7 million
- Cash on hand of $156.1 million [11]
Just as important for the stock narrative, GeneDx raised full-year 2025 guidance, including revenue of roughly $425–$428 million, and pointed to continued growth in exome/genome volume and revenue plus strong adjusted gross margin expectations. [12]
If you’re trying to understand why WGS can fall 7% in a day without “breaking” the bull case, this is the reason: the market is trading the gap between (A) a business that’s executing and (B) a stock price that often moves faster than fundamentals can comfortably follow.
Analyst forecasts and price targets for WGS: why the numbers don’t match
If you look up “GeneDx stock forecast” today, you’ll quickly discover something hilariously inconvenient: different data providers show meaningfully different consensus targets.
Here’s what current aggregations are indicating:
- One market summary put GeneDx at a “Moderate Buy” consensus, with an average target around $134.78 and a stated target range roughly $140 to $170 (with a mix of Buys, Holds, and a Sell). [13]
- A separate institutional/analyst compilation pegged the average one-year target at $164.11, with forecasts ranging from about $141.40 up to $194.25. [14]
- Another forecast page showed a “Strong Buy” style consensus and an average target around $135, with a wide spread from $80 to $200. [15]
Why this happens (and why it matters for investors)
These discrepancies usually come from some combination of:
- different “as of” dates,
- different analyst rosters included/excluded,
- stale targets that haven’t been updated after a rapid price move,
- and different ways of calculating averages (mean vs. median; inclusion of old outliers).
Practical takeaway: treat price targets as sentiment indicators, not precision instruments. When a stock is as fast-moving as WGS, the more informative question often becomes: Are targets rising or falling over time, and are the analysts changing ratings—not just numbers?
Valuation debate: “40% undervalued” vs. “expensive vs peers”
The valuation argument around GeneDx is currently split into two camps:
Camp A: Model-based upside
A Simply Wall St-style discounted cash flow framing, republished in market chatter, suggested GeneDx could be materially below a modeled intrinsic value (one figure cited was around $253 in a two-stage FCFE approach). [16]
Camp B: Multiples look rich relative to the sector
At the same time, other valuation dashboards flag GeneDx as expensive on price-to-sales versus peers, with one widely referenced snapshot showing a P/S around 10.8x and explicitly calling it pricey relative to a peer average. [17]
These can both be “true” in the annoying way finance often is: DCF-style models can justify big upside if high growth and margins persist; multiples can look stretched because the market is already paying up for that growth.
Institutional positioning and options sentiment: a quick read on the crowd
A recent institutional/derivatives summary reported:
- 543 funds/institutions with reported WGS positions
- A put/call ratio around 1.42 (often interpreted as more bearish positioning in options markets) [18]
This same dataset highlighted several major holders and noted at least one large position increase during 2025 reporting periods. [19]
None of this predicts tomorrow’s candle. But it helps explain why WGS can trade like a battleground: it’s liquid enough for institutions and active traders, and it has enough narrative power (genomics + scale + margin expansion) to attract both long-term holders and short-term momentum money.
How WGS has performed in 2025 (and why that sets up days like today)
GeneDx entered 2025 around $76.86 and was trading around $140.74 by mid-December—up roughly 83% year-to-date, according to one market data summary. [20]
When a stock is up that much, “random” selloffs stop being random and start being structural: funds rebalance, traders de-risk, and any macro wobble can trigger a sharper-than-expected downdraft.
What investors are watching next for GeneDx stock
If you’re tracking GeneDx as an investor (or as a sentient chart with feelings), the next catalysts usually fall into a few buckets:
- Evidence flywheel: more peer-reviewed results and real-world utility proof points that move payer coverage and clinician adoption (the GUARDIAN/JAMA recognition fits here). [21]
- Execution vs. expectations: can GeneDx continue delivering the growth/margin profile implied by its raised 2025 guidance? [22]
- Analyst narrative stability: do recent target hikes (e.g., Canaccord/BTIG/Wells Fargo notes in circulation) translate into broader consensus upgrades—or do targets lag price volatility and become less relevant? [23]
- Insider and institutional tape: not because “insiders always know,” but because headline-driven flows can amplify volatility—especially when sell-to-cover transactions get summarized as “insider selling.” [24]
- Macro regime: in risk-off sessions, high-multiple healthcare growth names can get hit regardless of company-specific performance. [25]
Bottom line
As of Dec. 16, 2025, the GeneDx stock story is still the same core paradox—just with a louder soundtrack:
- The business has been posting strong growth and raising guidance. [26]
- The stock is priced like the market expects that strength to persist—and it reacts violently when positioning shifts. [27]
- The Street remains broadly constructive, but “consensus” targets vary widely depending on the source you use. [28]
