PMI / ISM
EN: PMI / ISM Manufacturing / ISM Services PT: PMI / Índice de Gerentes de Compras
Los índices PMI/ISM son los leading indicators más confiables — encuestas a managers de purchasing sobre orders, production, employment, prices, y inventories. El threshold 50 separa expansión de contracción. ISM Manufacturing < 50 por 6+ meses históricamente = recession. Release rápido (1er día hábil del mes) = adelanta al NFP.
Qué son PMI e ISM
Los PMI (Purchasing Managers' Index) son encuestas mensuales a purchasing managers en companies acerca de business conditions. Existen dos proveedores principales en USA: (1) ISM (Institute for Supply Management): US-only. Largest, most watched. Publishes ISM Manufacturing (1st business day of month) y ISM Services (3rd business day). (2) S&P Global PMI (formerly Markit): international scope. Publishes flash PMI (mid-month preview) y final PMI (early next month). More comparable across countries. Methodology: both surveys ask purchasing managers about 5 key components: (1) New Orders: customer demand, leading indicator for production. (2) Production: current output levels. (3) Employment: hiring/firing. (4) Supplier Deliveries: speed of deliveries (slower = more demand usually). (5) Inventories: inventory changes. Respondents indicate if each metric is higher, same, or lower than previous month. Diffusion index calculation: % higher + 0.5 × % same = diffusion index. Result ranges 0-100. The magic number 50: Above 50: expansion (more respondents reporting growth than contraction). Below 50: contraction. Equal to 50: no change. Higher = stronger, lower = weaker. Manufacturing PMI: surveys ~300 manufacturing companies. Dominant sector history pero now only ~10% of US economy. Nonetheless important because: (a) leading indicator for broader economy, (b) sensitive to inventories/capex, (c) global trade proxy. Services PMI: surveys ~300 non-manufacturing companies. Dominant sector now (~90% of US economy). Healthcare, financial services, retail, technology, hospitality all represented. Composite PMI: weighted average de Manufacturing + Services. Most comprehensive single number. Release cycle: S&P Global Flash PMI: approximately 23rd of month, preview. ISM Manufacturing: 1st business day of month, 10am ET. ISM Services: 3rd business day of month, 10am ET. Final S&P Global PMI: early next month, confirmation. Market-moving: ISM Manufacturing, ISM Services most important USA.
Por Qué PMI es Leading Indicator
El PMI es considerado uno de los mejores leading indicators por varios razones. (1) Rapidity: released al inicio del mes siguiente. Manufacturing PMI on 1st business day = typically before NFP (1st Friday). Earliest major macro data point for the new period. (2) Direct business input: purchasing managers have visibility into forward pipeline. Incoming orders indicate future production, future employment, future revenue. Leading 1-3 months ahead. (3) Broad economic coverage: captures cross-sector dynamics. Services PMI covers 90% de US economy. Manufacturing PMI acts as international trade proxy. (4) Simplicity: single number (50 threshold) makes directional interpretation easy. No nuances like unemployment rate or GDP components. (5) Historical track record: ISM Manufacturing below 50 for 6+ consecutive months historically = recession most times. Exceptions: 2015-2016 (manufacturing recession without economy-wide recession), 2022-2023 (sustained below 50 without recession yet). Specific leading characteristics: New Orders sub-index: most leading. 3-6 months before actual production reflects economic direction. Reliable recession predictor. Employment sub-index: leading indicator for NFP (even though both released same month). Prices sub-index: leading inflation indicator. Rising prices in ISM = inflation building. Fed watches. Tradable relationships: Manufacturing PMI moves equities: rising PMI = rising stocks historically. Correlation strong 2010s. Weakened 2022-2024 (services-driven economy). Services PMI moves stocks more now: since 90% economy services. PMI surprises move bonds: hot PMI = hawkish = bond selling. Cool PMI = dovish = bond buying. Currency impact: strong USA PMI = USD strength vs. weaker international. Comparison across regions: Chinese PMI: official NBS (government) + Caixin (private). Both watched closely. China PMI leads global manufacturing. Eurozone PMI: S&P Global. Germany, France most important. Below 50 often due to energy (2022) o demand (2024). Japan PMI: au Jibun (formerly Jibun). Less market-moving but relevant. Historical breakdowns: 2020 COVID: Manufacturing PMI crashed from 49 (Feb) to 41 (April). Recovery to 59+ by year-end (V-shaped). 2022-2023 tightening: Manufacturing PMI fell below 50 by September 2022, stayed below through 2024. Deepest was 46. Signaled ongoing recession risk. 2024 divergence: Manufacturing below 50 (contracting) while Services 53+ (expanding). Services-led economy resilience.
Componentes y Interpretación
Analyzing individual PMI components provides deeper economic insight. (1) New Orders Index: most forward-looking component. Above 55: strong demand, production acceleration coming. Below 45: collapsing demand, contraction imminent. 50: neutral. Currently 2024: ~50-52 ISM Manufacturing (mixed). Historically the single best leading indicator of US economic activity. (2) Production Index: current output. Lags new orders by 1-2 months. Above 55: strong output. Below 45: production declining. Reflects current economic conditions. (3) Employment Index: hiring/firing by manufacturers. Above 50: hiring. Below 50: layoffs. Leading indicator for NFP Manufacturing sector specifically. (4) Supplier Deliveries Index: counterintuitive metric. Above 50 (slower deliveries) = MORE demand (suppliers backed up). Below 50 (faster deliveries) = LESS demand (suppliers have capacity). 2021 peak: 78 (extreme supply chain stress). 2024: ~50 (normalized). (5) Inventories Index: Above 50: rising inventories. Could indicate building to meet demand (bullish) o over-production (bearish depending on demand). Below 50: inventory reduction. Similarly ambiguous. Key interpretation: Customer Inventories (separate question) — low = customers will re-order (bullish). (6) Prices Paid Index: costs manufacturers pay for inputs. Above 50: rising prices. Leading indicator for inflation. 2021-2022 peaked 90+ (massive inflation pressure). 2024: ~55 (moderate). Fed watches closely. Overall interpretation: Healthy expansion: Composite PMI 54-58, New Orders leading, Employment positive, Prices stable. Transitional/cooling: PMI 50-54, New Orders flat, Prices moderating. Contraction: PMI 45-50, New Orders falling, Employment negative, Prices deflating. Deep recession: PMI below 45. Rare historically (2008, 2020). Sub-indices for sector rotation: Prices rising fast: commodity bullish, XLE/XLB outperform. Employment declining: defensive rotation, XLP/XLU. New Orders surging: cyclicals bullish, XLI/XLY. Supplier deliveries slowing: inflation coming, hedge strategies. Comparing Manufacturing vs Services: Both strong: broad expansion, long cyclicals. Manufacturing weak, Services strong: 2022-2024 scenario. Services-driven economy. Favor financial services, hospitality, healthcare over industrials. Both weak: broad recession warning. Defensive positioning. Rare configuration. Manufacturing strong, Services weak: unusual. Might indicate goods recovery, spending shift.
Impacto en Mercados
El PMI/ISM releases son consistentemente market-moving events. ISM Manufacturing (1er día hábil del mes, 10am ET): Surprise hot (above consensus): bullish stocks initially (strong economy), bearish bonds (rates up), USD strong. But nuanced — si above 55+ with strong prices = Fed hawkish concern. Surprise cool (below consensus): bearish stocks initially (economic weakness), bullish bonds (rates down), USD weak. But below 45-46 = recession fear, all risk assets down. In-line: muted reaction. Specific market reactions historically: 50-52 range (typical 2024): SPY moves 0.2-0.5%, TLT 0.3-0.5%, DXY 20-30 bps. Big surprises (1+ pts above/below): moves double. Recession threshold cross (below 45): VIX spike, risk-off. ISM Services (3rd business day): more recently more market-moving than Manufacturing (reflects US economy composition). Similar reactions. Sector rotation implications: Rising PMI: cyclicals outperform (industrials XLI, materials XLB, small caps IWM). Falling PMI: defensives outperform (staples XLP, utilities XLU, healthcare XLV). Prices Paid rising: commodity producers benefit (XLE energy, XME mining). Prices Paid falling: consumers benefit, downstream stocks. Pre-PMI positioning: typically difficult to predict surprises. Traders use: (1) S&P Global Flash PMI from previous week as preview. (2) Regional Fed surveys (Philly Fed, Empire State) released mid-month as preview. (3) Incoming data (PPI, imports, production) as consistency check. Correlation with stocks: historically strong. Manufacturing PMI y S&P 500 YoY change correlation ~0.6-0.7. Weakened in 2022-2024 (services-led). Currency impact: strong USA PMI + weak European PMI = bullish USD vs. EUR. DXY moves 20-50 bps typical on major PMI divergences. Crypto: risk-on asset. Strong PMI = bullish crypto (economy healthy, risk-on). Weak PMI = bearish crypto. Correlation increased 2022-2024 as crypto became more macro-driven. Credit implications: weak PMI = credit spreads widen (default risk rising). Strong PMI = spreads narrow. High-yield credit especially sensitive. HYG (HY ETF) moves with PMI direction. International PMI: Chinese PMI: leading indicator for global manufacturing, commodity demand. China PMI improving = bullish commodities, materials. Eurozone PMI: affects European stocks, EUR. 2022-2023 persistent weakness = bearish EU stocks. Japan PMI: less impactful but relevant for Japanese equities, Yen.
Trading PMI/ISM Events
El trading PMI/ISM requires different approach than NFP o CPI. Release day dynamics: 10am ET: release. First 2-3 minutes often chaotic. 10:00-10:15am: initial reaction forming. 10:15-11:00am: broader position adjustment. Volatility higher than average mid-morning. Rest of day: normal trading pero PMI-informed positioning. Strategies: (1) Directional views: si confident en PMI direction (based on flash PMI, regional Fed data, PPI, etc.), take directional stance. Easier than NFP since single-factor data. (2) Sector rotation plays: most common. Strong PMI: long XLI/XLB/XLF. Weak PMI: long XLP/XLU/XLV. Adjust weekly based on incoming PMI. (3) Bond/stock relative plays: hot PMI = long stocks/short bonds (via TLT puts). Cool PMI = reverse. (4) Volatility plays: straddles/strangles pre-release. Expected move for SPY on ISM Manufacturing day ~0.3-0.5% (smaller than NFP). Straddle strategies work if surprise significant (>1.5 point deviation). (5) Pair trades: Manufacturing vs Services divergence. 2022-2024: long XLV (healthcare) vs short XLI (industrials) during manufacturing weakness. Worked well. Specific PMI trading setups: Setup 1: 50 crossing: when PMI crosses above/below 50, often signals regime change. Long equities on crosses above 50, reduce on crosses below. Setup 2: Deep contraction recovery: PMI below 45 followed by rise above 45 = strong recovery signal. 2009, 2020 examples. Massive rallies follow. Setup 3: Sustained weakness: PMI below 50 for 6+ months = recession warning historically. Defensive positioning. Setup 4: Prices Paid surge: Prices Paid jumping 10+ points in 2-3 months = inflation building. Bullish commodities, hawkish Fed concern. International PMI combinations: US + Europe + China all weakening: global recession signal. Full defensive. US strong, others weak: USA outperformance trade. Long SPY vs. short ACWI ex-US (EFA). Europe/China recovering, USA flat: rotation to international. Manufacturing PMI globally strong: bullish copper (Dr. Copper), commodities, emerging markets. Risks y caveats: (1) Survey-based data: sentiment can disconnect from hard data. PMI can lead by too much, triggering false signals. 2022-2024 Manufacturing below 50 didn't cause recession. (2) Sector mix evolution: Manufacturing declining importance in modern economy (~10%). Services matters more now. (3) Less reliable below 50: historically clearer at extremes. Mid-50s ambiguous often. (4) Revisions: PMI rarely revised but methodology changes periodically. Using PMI with other indicators: best practice is combine PMI with NFP, CPI, GDP data for comprehensive macro view. No single indicator perfect. PMI's strength: speed (released early). Weakness: sentiment-based, not hard data.
