Sharp vs. Square Divergence
Spotting value where experts and public disagree.
Overview
This pillar identifies crucial differences between sophisticated 'sharp' traders and the general public or 'square' money. By tracking this divergence, it helps uncover markets where popular opinion is wrong, presenting unique trading opportunities.
What It Does
It aggregates sentiment data from two distinct cohorts: verified expert traders with high accuracy ratings and the broader retail market. The pillar then calculates a 'divergence score' that measures the magnitude and direction of disagreement between these groups. This score highlights assets that are either overvalued by the public or undervalued by the masses but favored by experts.
Why It Matters
Markets are often moved by popular sentiment, but long-term value is typically identified by informed experts. A significant divergence signals a potential mispricing, offering a powerful edge by indicating when to bet against the crowd and avoid hype-driven bubbles.
How It Works
First, we classify traders into 'sharp' and 'square' categories based on their historical accuracy, portfolio size, and trading frequency. Second, we calculate a weighted sentiment score for each group on a given market. Finally, the pillar subtracts the square sentiment from the sharp sentiment to produce a single divergence score, indicating where smart money is placing its bets relative to the public.
Methodology
The Sharp Sentiment Score (SSS) is a weighted average of predictions from traders with >70% historical accuracy and a portfolio value in the top 10th percentile. The Square Sentiment Score (QSS) is a simple average of all other traders. The Divergence Index (DI) is calculated as DI = SSS - QSS, normalized on a scale from -100 to +100. Analysis is typically run on a 7-day rolling window to capture recent shifts.
Edge & Advantage
This pillar provides a clear, data-backed signal to fade public hype or identify contrarian bets, moving beyond simple sentiment analysis.
