2. Return and risk (ch.5)

Statistics use the 60 complete months to Sep 2026.

Statistic Value What it means
Arithmetic mean (annualized) 75.0% Expected one-period return if the past repeats
Geometric mean (CAGR) 72.7% What a buy-and-hold investor actually earned; the gap ≈ σ²/2 is volatility drag
Standard deviation (annualized) 67.9% 4.3× the S&P 500's 15.7%
Skewness / excess kurtosis 1.49 / 4.28 Right-skewed, fat tails vs normal
5% monthly VaR: historical / normal -16.5% / -26.0% One month in 20 loses at least this much
5% monthly expected shortfall -24.0% Average loss in that worst 5% of months
Sharpe ratio (S&P 500) 1.05 (0.67) Excess return per unit of total risk
Sortino ratio 2.59 Excess return per unit of downside risk
Max drawdown, 5y -57.6% (trough Apr 2025) Currently -12.3% from the peak

Risk

3. Index model, CAPM and factors (ch.8–10)

Regression (60m excess returns) Alpha (ann.) t(α) Beta t(β) R² Residual σ
vs SPY +48.1% 1.80 2.23 4.54 0.26 58.3%
vs SOXX +28.3% 1.42 1.39 9.30 0.60 43.0%
  • Risk decomposition (ch.8): systematic variance β²σ²(M) = 12.2% vs firm-specific σ²(e) = 34.0%, so 26% of the risk is market-driven and 74% is diversifiable.
  • CAPM required return (ch.9): k = r_f + β × MRP = 4.02% + 2.23 × 5.5% = 16.3% (Blume-adjusted β 1.82 → 14.0%, used as the DCF discount rate).
  • Historical alpha of +48.1% a year has a t-stat of 1.80: not statistically distinguishable from zero (ch.11: past alpha is a weak guide).
  • Fama-French 5 factors + momentum (ch.10, 150 months to Jul 2026): R² 0.36, alpha +23.8% (t 1.86). Loadings: Mkt-RF +1.74 (t 6.7), SMB -0.53 (t -1.2), HML +0.66 (t 1.6), RMW -2.30 (t -4.7), CMA -0.28 (t -0.5), Mom +0.00 (t 0.0). The loadings describe a large-cap, value, low-profitability return profile (SMB > 0 small-cap, HML < 0 growth, RMW < 0 weak profitability, CMA < 0 aggressive investment).

Rolling beta

4. Portfolio fit: allocation and diversification (ch.6–7)

Correlation of monthly returns with MU (60m): SOXX 0.77, SPY 0.51, WDC 0.73, STX 0.76, INTC 0.65, AMAT 0.60, LRCX 0.79.

  • A 50/50 mix with SPY would have had volatility of 38.6% vs 41.8% for the weighted average of the two, a diversification benefit because ρ = 0.51 < 1.
  • Optimal risky share y* = [E(r) − r_f] / (A·σ²), holding MU alone against T-bills (σ = 67.9%):
Risk aversion A y* with CAPM E(r) y* with E(r) + Street α
2 13% 18%
3 9% 12%
4 7% 9%
6 4% 6%

Even a risk-tolerant investor would put only a modest share in a single stock this volatile. Ch.7–8 say the efficient choice is the market portfolio plus a Treynor-Black tilt (section 9), not a concentrated position.

Fundamentals

  • DuPont, TTM: ROE 74.9% = net margin 55.9% × asset turnover 0.93 × leverage 1.43. Relative to typical levels (10% margin, 0.8 turnover, 2.0 leverage) the biggest driver is net margin.
  • Cash conversion: TTM operating cash flow 51.4bn vs net income 50.5bn. The accruals ratio of -1.0% of assets is negative (cash earnings exceed accounting earnings), a sign of high-quality earnings.
  • Stock-based compensation of 1.2bn TTM (1.3% of revenue) is a real cost to shareholders. The valuation below uses FCF after SBC (owner FCF margin 27.7%). Buybacks were n/a; share count changed +0.9% over the year.
  • Operating leverage (ch.17): degree of operating leverage 13.34 (last two fiscal years): each 1% change in sales moved EBIT by about 13.3%.

Growth embedded in the price (PVGO). With FY2028E EPS of USD 206.68 and k = 14.0%, the no-growth value E₁/k is USD 1,473.84. PVGO = USD -409.88, which is -39% of the price: the price is below the no-growth value, so the market expects earnings to shrink or doubts their durability. No-growth P/E = 1/k = 7.1x vs the actual 5.1x.

Constant-growth check. On TTM owner FCF, P = FCF₁/(k − g) implies a perpetual growth rate of 11.8%, above the 4% long-run nominal-GDP ceiling the book recommends for g.

Scenario DCF (owner FCF, k = 14.0%, terminal g = 4%). The revenue path is FY2027 (274.9bn), then the FY2028 low/avg/high estimate, then growth that fades linearly to 4% over 8 years. Owner-FCF margin ramps from today's 27.7% to the scenario margin over 3 years. Scenario assumptions are generic (derived from consensus growth and today's owner-FCF margin).

Scenario FY2028 revenue Growth after Owner-FCF margin FY2036 revenue Terminal value share Value / share vs price
Bear 127.4bn 5% 21% 184bn 43% USD 261 -76%
Base 314.4bn 11% 28% 569bn 47% USD 898 -16%
Bull 396.6bn 16% 35% 891bn 49% USD 1,628 +53%

Reverse DCF: what today's price assumes. On the base revenue path the price requires a steady-state owner-FCF margin of 33%. At the base 28% margin it requires 16% growth after FY2028, or a discount rate of 12.6% (vs the model's 14.0%).

Sensitivity: base revenue path, value per share by discount rate (rows) and steady-state owner-FCF margin (columns).

Earnings-multiple cross-check: FY2028E EPS USD 206.68 × 20x = 4,134, 25x = 5,167, 30x = 6,200, 35x = 7,234, 40x = 8,267, 45x = 9,300. The price implies 5x. The FY2028 EPS range across analysts is 161.00–335.50.

2024-09-25 2024-09-26 1.18 vs 1.11 5.9% +14.0% +14.6% -1.7%
2024-06-26 2024-06-27 0.62 vs 0.53 17.3% -7.5% -7.1% -20.8%
2024-03-20 2024-03-21 0.42 vs -0.24 273.8% +13.6% +15.1% +3.0%
2023-12-20 2023-12-21 -0.95 vs -1.01 5.8% +7.3% +5.7% -2.6%
2023-09-27 2023-09-28 -1.07 vs -1.18 9.3% -5.2% -0.4% -1.8%
  • Average absolute day-0 abnormal move: 8.6%. The sign of the EPS surprise matched the sign of the reaction 42% of the time, which is close to a coin flip: guidance and commentary matter more than the headline EPS beat.
  • Post-announcement drift: the correlation between the initial reaction and the next-20-day drift is 0.11. There is no reliable post-earnings drift, consistent with semi-strong efficiency.

9. Treynor-Black: should an active manager overweight it? (ch.27)

Step Value
Analyst-implied 12m return (mean target / price − 1) +44.3%
CAPM 1-year required return (raw β) 16.3%
Raw alpha +28.0%
Minus average analyst optimism bias (Top-30 cross-section) -9.9%
Shrunk alpha (× 0.25, for forecast imprecision) +4.5%
Residual variance σ²(e) 34.0%
Initial active weight w₀ = [α/σ²(e)] / [E(R_M)/σ²_M] +6.0%
Beta-adjusted weight w* = w₀ / [1 + (1 − β)w₀] +6.4%

A positive weight means an active manager would hold more than its index weight. The weekly Top-30 pipeline, which uses the same method, gives +3.8% in the combined 30-stock active portfolio.

  • Earnings-implied move: the jump in variance from the 2026-12-18 expiry (IV 48%) to 2027-01-15 (IV 49%) prices an earnings-day move of ±6.4% (1σ), or about ±5.1% in absolute terms (≈ ±54). Compare the historical average absolute reaction of 8.6% in section 7.
  • Implied vs realized: the ~1-month ATM IV is 47% vs realized 47% (20d) / 75% (60d) / 80% (1y). Options are cheap relative to recent realized volatility, so buying protection is relatively inexpensive.
  • Put-call parity (ch.20): at the ATM strike for 2026-11-06, C − P − (S − PV(K)) = -0.02 per share. Close to zero, as parity requires.
  • Quotes were unavailable when the data was pulled (outside market hours), so implied vols use each contract's last trade price. Treat them as approximate; illiquid strikes can be stale.

Qualitative notes reviewed 2026-10-06

These notes are written by hand, unlike the auto-refreshed numbers above. Events up to late 2025 come from company announcements. Later developments are inferred from the data (consensus estimates, price reactions) and should be checked against MU's 10-Q/10-K filings and earnings calls.

Business in one paragraph

Micron is a memory manufacturer focused on DRAM, NAND and high-bandwidth memory used in PCs, phones, data centers, automotive and industrial devices. Memory is cyclical, but AI servers have shifted investor focus toward HBM, advanced DRAM and enterprise SSDs. Micron competes mainly with Samsung and SK hynix, and its returns depend on industry supply discipline, technology transitions and pricing. The investment case hinges on whether AI memory demand can keep DRAM tight enough to offset normal consumer-device cycles and the heavy capital spending required for leading-edge fabs.

Key developments

When Event Why it matters
Feb 2024 Began volume production of HBM3E for AI accelerators Put Micron into the fastest-growing memory category tied to NVIDIA-class AI systems.
2024 Management said HBM supply for 2024 was sold out and 2025 mostly allocated Indicated that AI demand was tightening industry supply earlier than a normal memory upcycle.
Dec 2024 US Commerce finalized CHIPS Act support for Micron's Idaho and New York projects Strengthened the domestic manufacturing story and helped offset the cost of US fabs.
Jun 2025 Micron shipped HBM4 samples to key customers (reported) Showed progress toward the next AI-memory generation and potential share gains.
Jun 2025 Micron announced expanded US investments in DRAM manufacturing and research (reported) Reinforced long-term capacity ambitions, while raising the importance of supply discipline.

PEST analysis

Factor Tailwinds Headwinds Net
Political US policy favors domestic memory capacity for AI and defense. CHIPS incentives support Idaho and New York expansion. China restrictions, export controls and geopolitical concentration in Asian memory supply chains can disrupt demand and equipment access. ⚖️
Economic AI servers use far more DRAM and HBM than traditional servers. Industry supply discipline can produce powerful margin recovery. Memory remains cyclical, commodity pricing can fall quickly, and fab capex is large before cash returns arrive. ⚖️
Social AI services, smartphones, PCs and autos all need more memory over time. Micron benefits from being the US-based memory champion. End-market weakness in phones or PCs can still swamp AI strength. Local opposition or labor shortages can slow fab projects. ⚖️
Technological HBM3E, HBM4, advanced packaging and process-node transitions create differentiation. AI accelerators require close memory supplier partnerships. SK hynix leads parts of HBM, Samsung can add capacity, and customer qualification cycles are demanding. NAND remains competitive. ✅

Bull case vs bear case

  • Bull: HBM demand stays supply-constrained, Micron gains share at leading AI customers, and broader DRAM pricing remains disciplined. The cycle becomes less volatile as AI servers absorb a larger share of bits.
  • Bear: Competitors add HBM and DRAM capacity faster than demand, consumer devices soften, or Micron misses qualification windows. The market could then revert to the familiar memory pattern of falling prices and margin compression.

Catalysts to watch (next 6–12 months)

  1. Late December 2026 or early January 2027 fiscal Q1 results and HBM revenue mix.
  2. Customer qualifications for HBM4 and next-generation AI platforms.
  3. DRAM and NAND pricing trends through PC, smartphone and server channels.
  4. Capital-spending guidance and supply-discipline commentary from all major memory makers.
  5. Idaho and New York fab construction milestones and CHIPS funding updates.
