Is Fulcrum Therapeutics, Inc. (FULC) a good stock to buy?
What we have tested leans negative. To like it anyway you need a reason our checks do not capture.
What each rating means, in numbers
Can it survive? — Middling. Safer than 41% of the companies we cover, judged on the warning signs that came before companies that really did fail.
Business quality — Middling. Passes 3 of the 7 health checks we can measure — things like making a profit, turning it into cash, and not piling on debt. Across 131,000 company-quarters the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, in every era and all twelve sectors.
How wild is the price? — Very wild. The share price swings about 90% in a typical year, which puts it in the most volatile fifth. Out of every 100 companies that swung like this, about 8.6 went bankrupt within the year. Across the three periods we tested that ran from 3.7% to 11.5%.
What "tested" means here, and why there is no score out of 100
Tested means the read was measured against what actually happened afterwards, on a history that keeps the companies that were later delisted, using only figures that had been filed on the day they are used. Survival was ranked on companies that really did fail. What an owner keeps was tested across the universe from 2011 to 2025.
The full record of everything we have tested is on the research pages.
Which benchmark. Over the period we tested, the median listed company returned +5.8% a year while the S&P 500 returned about +13.9% — the index is weighted by size and was carried by a handful of enormous winners. So "beats the index" and "beats the other companies you could have bought" are different questions. Where a read says it picks better companies, it means the second one. None of these gets you an index fund's return, and we would rather say that than imply otherwise.
The quality read is the strongest thing we have tested: 131,000 company-quarters across 5,300 companies, where the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, holding in every era and all twelve sectors. It still says less likely to break, not likely to beat the market — every band in that study lost to the index at the median, because the median listed company does.
Each read is shown on its own rather than merged into a single score, so you can see which part is strong and which is weak instead of taking an average on trust.

📍 Where to start on this page, and what to look at first
How to read FULC (pre-profit growth)
This company is reinvesting instead of generating profit, so a standard DCF cannot price it. The useful question is whether the growth the market is paying for is achievable — and whether the company can fund itself until then.

Who owns FULC, and how it moves
From the SEC's own filings: every fund manager over $100M reports its holdings each quarter, and every officer and director reports theirs. Each point is what was public at the time.
155 institutions reported holding it at the latest quarter-end. Above 100% is not a mistake in the filings: when a fund lends shares to a short seller, the fund and whoever buys the borrowed shares can both report them.
Riskier than 59% of the stocks we cover
What this rating means, and what it does not
What this rank is — Middling. Riskier than 59% of the companies we cover. Out of every 100 companies ranked here, about 0.2% went bankrupt within the year, against 0.6% for the average company we cover. The rank comes from a model trained on every US filing since 2012, including 823 companies that really did fail, and scored each year by a version that had not seen that year.
What it is not — Not a trade. We tested shorting these names and buying puts, spreads, straddles and condors on them at real option prices, 2010-2025. Every version lost money: the market already prices the distress and the survivors squeeze. A high rank is a reason to read the filings and to size for a total loss, not a reason to bet against the company. A low rank says the balance sheet is calm, not that the price is sensible.
▾ The numbers, the logic, and why not to trade on it
The logic. A model trained on every US filing since 2012 — including 823 companies that went bankrupt or stopped trading under a dollar — ranks each covered stock by its chance of failing in the next year, from its latest filing, price history and credit conditions. The rank is a position among peers; the table is a count of what happened to stocks in each position, scored each year by a model that had not seen that year.
| Rank band | went bankrupt within 12 months | fell 80% or more (or failed) within 12 months | fell 50% or more (or failed) within 6 months |
|---|---|---|---|
| All covered stocks (average) | 0.59% | 4.21% | 8.51% |
| Healthcare (sector average) | 0.94% | 9.47% | 17.69% |
| riskiest 1% | 16.4% | 33.0% | 45.5% |
| next 2% (97-99) | 5.9% | 24.9% | 38.2% |
| next 2% (95-97) | 3.4% | 21.2% | 33.8% |
| next 5% (90-95) | 1.6% | 15.1% | 27.3% |
| next 15% (75-90) | 0.8% | 8.5% | 17.8% |
| next 25% (50-75) ← this stock | 0.2% | 2.7% | 6.2% |
| safest half | <0.1% | 0.5% | 2.1% |
Why not to trade on it. We tested shorting these names and buying puts, spreads, straddles and condors on them at real option prices, 2010–2025: every version lost money. The market already prices the distress, and the survivors squeeze. Use a high rank to read the filings and to size for a total loss — not to bet against the company. A low rank says the balance sheet is calm, not that the price is sensible.
Scored from the most recent SEC filing we had (dated 2026-04-28), which can be a quarterly report newer than the yearly figures used elsewhere on this page; scores last updated 2026-09-18. Within Healthcare: rank 40 of 100. Rough one-year odds for this stock alone: bankruptcy 0.1%, an 80% fall 10.3% (the model overstates the middle of the range).
▾ The logic, and why not to buy on it
The logic. Trained on 2,900 acquisitions since 2012, the model leans on size (small), age, retained earnings, asset growth, volatility and how many deals the sector has just seen. Announcement = the day the stock jumped, not the day the paperwork was filed.
| top 1% | 15.4% acquired within a year |
| next 2% (97-99) | 10.3% acquired within a year |
| next 2% (95-97) | 9.0% acquired within a year |
| next 5% (90-95) | 7.3% acquired within a year |
| next 15% (75-90) | 6.4% acquired within a year |
| next 25% (50-75) ← this stock | 4.8% acquired within a year |
| bottom half | 3.0% acquired within a year |
Why not to buy on it. A takeover paid a median +22% on the day — but even in the top band about 6 in 7 companies are not bought, and those lag. Buying the whole top list returned what the S&P 500 did (2012–2023), and adding "cheap" or "beaten-down" filters did not change that. Read it as context for a thesis you already have, never as the thesis.
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
What these health ratings mean, in numbers
Business quality — Middling. Passes 3 of the 7 health checks we can measure — making a profit, turning it into cash, not piling on debt, not issuing shares. Across 131,000 company-quarters the weakest scorers went on to fail at 5.4% within a year against 1.4% for the strongest, and that held in every era and all twelve sectors. It says "less likely to break", not "likely to beat the market".
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
The Z-score needs working capital, retained earnings, EBIT, sales and total assets from the latest balance sheet, and at least one of those isn't reported in machine-readable form here — common for foreign private issuers. We leave it blank rather than compute a distress verdict from an estimated input. It doesn't affect the reported figures in the financial tables below.
▾ The checks — what passed, what didn't (and what we couldn't measure)
-
✗ Positive net incomeNet income -$74.9M in FY2025.Why this matters: Does the company actually earn a profit? Sustained losses eventually force it to raise money — diluting you — or take on debt.
-
✗ Positive operating cash flowOperating cash flow -$60.1M (was -$2.2M the prior year).Why this matters: Profit can be an accounting figure; cash from running the business is harder to fake. Negative operating cash flow means the core business consumes cash and must be funded externally.
-
✓ Cash flow backs up reported profitOperating cash flow -$60.1M vs net income -$74.9M.
-
✗ Return on assets improvingReturn on assets -20.4% vs -3.7% a year ago.Why this matters: Is the company squeezing more profit out of each dollar of assets than last year? Rising = getting more efficient; falling = the opposite.
-
✓ Debt load (vs assets)The filing reports no interest-bearing debt in either year (total assets $366.3M).
-
✓ Short-term liquidity (current ratio)Current ratio 27.40x vs 22.63x a year ago.
-
✗ Share count (dilution)Share count rose 2.2% (0.1M → 0.1M year-over-year).Why this matters: Issuing lots of new shares splits the pie into more pieces, shrinking your slice. Stable or falling share count protects existing owners.
-
· Pricing power (gross margin) (n/a — data not reported; not scored)
-
· Sales per asset (asset turnover) (n/a — data not reported; not scored)
Missing data is never counted as a pass or a fail — it's shown as n/a and excluded from the denominator. Each check compares the company against its own prior year.
Plain English: the company holds about $198M in cash and is burning roughly $60M/year in operations. At that pace, the cash lasts 3.3 yrs before it must raise capital (diluting shareholders), take on debt, or cut spending.
Assumes constant burn and ignores financing/asset sales. For pre-profit biotech and growth companies, this matters more than a DCF — a great drug pipeline is worthless if they run out of money before approval.
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for Fulcrum Therapeutics because its operating cash flow is negative and it has not been profitable in the last five years. Investors are likely betting on the success of its drug pipeline and future revenue growth, rather than current cash flows. To value it, one would need to project the probability and timing of drug approvals and commercialization. The number one quantifiable risk is continued negative operating cash flow, which implies ongoing cash burn.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Phase 3 clinical trial results for lead candidates
- Regulatory approval decisions (e.g., FDA)
- New partnership announcements
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Revenue fell -100% to $0.
- Free cash flow is negative at -$72.8M — the cash burn widened vs last year.
- Still unprofitable at -$74.9M — loss widening.
Nothing was clearly improving year-over-year.

Revenue Drivers
Why Is It Priced Like This?
Why Customers Pay
What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is pricing Fulcrum Therapeutics based on expectations for its drug pipeline and future commercialization success, rather than current financial performance, as evidenced by negative net income and operating cash flow. The market may be assigning value to potential drug approvals and subsequent market penetration, which is not in the model. Its adequate current ratio of 27.4 provides some cash runway for these development efforts.
Business Model & Valuation
How They Make Money
The company funds its operations primarily through equity raises, given its negative operating cash flow and lack of dividends or buybacks.
Growth / Revenue DCF
Negative free cash flow: revenue/margin growth model used - standard FCF DCF is unreliable for companies still scaling.

What this model does NOT do: this is a consolidated owner-earnings cash-flow model. Standalone segment assumptions: none. It does not project its revenue segments independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.

These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.

Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.

Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.

- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- INVARIANT: weighted IV is non-positive. Model may not be appropriate.
- Model implies no positive equity value under these assumptions. Valuation is speculative/low-confidence.

| 2021 | -78.5M | 1.7M | 11.1M | -91.3M |
How we define FCF: operating cash flow − capital expenditure − stock-based compensation (owner-earnings basis — SBC is a real cost to shareholders even though it's non-cash). Latest year: -60.1M − 314,000 − 12.5M (SBC & adj.) = -72.8M. This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a projected from revenue × terminal margin, not this single year.
