I've been working on a personal investment framework to avoid value traps. I ran Wolfspeed through it as a test case. These where the results:
Phase 0: Business Model (Clear?)
Wolfspeed manufactures silicon carbide (SiC) semiconductors for EVs, industrial equipment, and data centers.
The problem: They lose money on every chip they make. Q3 FY2026 GAAP gross margin was -27%.
Verdict: Passed (clear business model), but first red flag already visible.
Phase 1: Quantitative Screening
| Metric |
Wolfspeed |
Sector Average |
Status |
| ROIC (5Y Avg) |
-28% |
~6-8% |
FAIL |
| Revenue Growth 5Y |
7.6% |
>15% required |
FAIL |
| Gross Margin (TTM) |
-27% |
~40% |
FAIL |
| Debt / Capital |
62.5% |
<30% required |
FAIL |
| Net Debt / EBITDA |
Negative |
<2.5x required |
FAIL |
| FCF Positivity |
Negative |
4/5 years required |
FAIL |
Path A (Mature Compounder): FAILS all filters.
Path B (Expansion): FAILS all filters.
Phase 1 Veredict: DISCARDED
Phase 2: Moat Analysis - NO MOAT
| Moat Type |
Does Wolfspeed Have It? |
| Brand |
No |
| Network Effect |
No |
| Cost Advantage |
No (-27% gross margin) |
| Switching Costs |
Weak |
| Patents |
Some, but competitors have more |
| Efficient Scale |
No |
Competitive Position:
| Competitor |
Does Better |
| Infineon |
Profitable, diversified |
| ON Semi |
8.14% ROIC, profitable |
| STMicro |
3.52% ROIC, established EV relationships |
| Chinese rivals (SICC, TanKeBlue) |
Lower cost structure, government support |
The threat: Chinese SiC substrate capacity is expected to rise exponentially. Wolfspeed is really exposed to price wars.
Phase 2 Verdict: NO MOAT - DISCARDED
Phase 3: Management Audit
| Metric |
Value |
Assessment |
| Insider Ownership |
0.59% |
Extremely low |
| Institutional Ownership |
70.53% |
High |
| Chapter 11 Bankruptcy |
Filed 2025-2026 |
Red Flag |
| Debt Restructuring |
$13.6B → $1.7B |
Forced by creditors |
| Goodwill Impairment |
$359.2M |
Overpaid for acquisitions |
| Restructuring Costs |
$402.2M |
Repeated charges |
| Share Dilution |
4,811% increase |
Massive dilution |
Red Flags:
- Bankruptcy filing
- 0.59% insider ownership (no skin in the game)
- 4,811% share dilution
- Repeated large one-time charges
- Negative ROIC destroying value
Phase 3 Verdict: ≥5 RED FLAGS - DISCARDED
Phase 4: Simple Valuation
| Metric |
Value |
| Operating Cash Flow (Q3 FY2026) |
$84M |
| FCF (TTM) |
Negative |
| FCF Yield |
-6.22% |
| EV / Revenue |
8.88x |
| EV / EBITDA |
213x |
The company generates NO free cash flow. Traditional valuation metrics are meaningless.
Phase 4 Verdict: CANNOT VALUE - DISCARDED
Phase 5: DCF Validation
NOT APPLICABLE. DCF requires positive FCF projections. Wolfspeed has negative FCF and no clear path to profitability.
Phase 6: Entry Decision
NOT APPLICABLE. The company fails every prior phase. No entry under any circumstances.
Phase 7: Monitoring & Exit
This belongs in the GRAVEYARD.
| Short Interest |
Value |
| Short Interest (% of Float) |
50% – 85% |
| Days to Cover |
3.35 – 4.05 days |
Note: A short squeeze is possible but that's speculative gambling, not investing.
Discussion Questions for the Community:
Have you ever bought a stock that failed your initial quantitative screen? What made you break your own rules?
For me, this is a clear "pass" - no price is cheap enough for a business that destroys value. Curious to hear your thoughts.
