Trading Glossary: ISM Manufacturing PMI, Insider Buying Clusters, and Fear & Greed Index

Published 1 July 2026 · Titan Foundry Desk

Three terms that appear constantly in market commentary but are rarely explained properly. This entry covers what each one measures, why it matters, and how experienced participants actually use the data.

1 of 3

ISM Manufacturing PMI

Full name: Institute for Supply Management Manufacturing Purchasing Managers’ Index

Release: First business day of each month · Source: ISM via survey of 400+ manufacturing firms

The ISM Manufacturing PMI is a diffusion index that measures whether the US manufacturing sector is expanding or contracting. It surveys purchasing managers at over 400 industrial companies and asks a simple question across several categories: is this improving, staying the same, or getting worse?

The magic number is 50. Above 50 signals expansion. Below 50 signals contraction. But experienced market participants know that the direction of travel matters as much as the absolute level. A reading of 48 that was 45 last month tells a very different story from a reading of 48 that was 52 last month.

Sub-components Worth Watching

The headline number gets the attention, but five sub-components carry the real information:

  • New Orders — the most forward-looking component; leads the headline by 1-2 months
  • Production — measures current output, confirms or contradicts new orders
  • Employment — feeds into NFP expectations; a PMI employment miss often precedes a weak jobs number
  • Supplier Deliveries — longer deliveries suggest supply constraints, which can signal inflationary pressure
  • Inventories — rising inventories with falling new orders is a recessionary combination

Why Traders Watch It

The ISM Manufacturing PMI lands on the first business day of each month, making it one of the earliest reads on economic activity. It often sets the tone for the entire week. A surprise miss can shift rate expectations within minutes. The July reading drops on Thursday 2 July this week, making this particularly timely.

Cross-reference ISM data with our session briefs to see how the release aligns with positioning and momentum across indices, commodities, and currencies.

Insider Buying Clusters

Source data: SEC Form 4 filings · Signal type: Behavioural · Lag: 2 business days (filing deadline)

When a company executive, director, or 10% shareholder buys or sells stock, they must disclose it within two business days via an SEC Form 4 filing. Individually, these filings tell you what one person did. In clusters, they tell you something far more interesting.

An insider buying cluster occurs when three or more insiders at the same company purchase shares within a short window, typically 30 to 90 days. The logic is straightforward: one insider buying might be routine diversification or option exercise. Three or more insiders buying with their own money, at roughly the same time, suggests they collectively believe the stock is undervalued.

Cluster vs Single: Why Clusters Carry More Weight

A single Form 4 filing is noisy data. CEOs buy stock for dozens of reasons: contractual obligations, signalling to shareholders, compensation plans. But when the CFO, two board members, and a divisional VP all buy within the same month, that noise drops significantly.

Academic research has consistently shown that clustered insider purchases outperform single-insider purchases over the subsequent 6 to 12 months. The signal is strongest when:

  • Purchases are made on the open market (not option exercises)
  • The dollar amounts are material relative to the insider’s compensation
  • The stock has been declining prior to the cluster (insiders buying weakness, not momentum)

Real-world Example: Nike

Nike has seen notable insider buying activity in recent quarters, with multiple board-level and executive purchases clustering during periods of share price weakness. When the people who see the order book, the pipeline, and the margin trajectory are buying the dip, that is qualitatively different from a retail investor doing the same thing.

Our ethical screener incorporates governance quality into its scoring. Insider buying clusters often correlate with higher governance scores because they indicate alignment between management interests and shareholder interests.

Fear & Greed Index

Publisher: CNN Business · Scale: 0 (Extreme Fear) to 100 (Extreme Greed) · Update: Daily

Current reading: 31.3 — Fear

CNN’s Fear and Greed Index aggregates seven market indicators into a single sentiment reading. It is not a trading signal. It is a temperature check on crowd psychology. At 31.3 today, the index sits in Fear territory despite NAS100 recently breaking 30,000. That divergence between price action and sentiment is, on its own, worth noting.

The Seven Components

Component What It Measures
Market Momentum S&P 500 vs its 125-day moving average
Stock Price Strength 52-week highs vs 52-week lows on NYSE
Stock Price Breadth Advancing vs declining volume (McClellan)
Put/Call Ratio Options activity skew towards puts or calls
Market Volatility VIX level relative to its 50-day average
Safe Haven Demand Stock returns vs Treasury bond returns
Junk Bond Demand Spread between junk bond yields and investment grade

The Contrarian Signal

The index is most useful at extremes. When it drops below 20 (Extreme Fear), it has historically corresponded with local bottoms. When it rises above 80 (Extreme Greed), corrections tend to follow within weeks. The middle ground, 30 to 70, is less actionable on its own.

The current 31.3 reading is notable because it sits just above the Extreme Fear threshold while equity indices trade near highs. This kind of divergence, price making new highs while sentiment stays cautious, can mean one of two things: either the rally has further to run because the crowd has not yet piled in, or the crowd is sensing something the price action has not yet reflected.

Neither interpretation is automatically correct. The value is in being aware of the divergence and watching what happens next.

Current Reading: 31.3 (Fear)

NAS100 above 30,000 with the Fear and Greed Index in Fear territory. Price and sentiment are telling different stories. Monitor whether they converge or one breaks first.

Our daily session briefs track sentiment readings alongside positioning data, volatility regimes, and macro context. The Fear and Greed Index is one input among many. Explore how these factors interact through our convergence screener, which identifies instruments where multiple quantitative layers align simultaneously.
