The sector momentum heatmap shows the recent performance of Borsa Istanbul’s 37+ sectors on a single visual. Each sector is colored by the 21-day average return of every stock it contains: shades of green represent rising sectors, shades of red represent falling ones. Sector tiles are sized in proportion to total market capitalization, so large sectors like banking take up more room on the map.
Academic research shows that assets with strong recent performance tend to continue outperforming in the short term. Narasimhan Jegadeesh and Sheridan Titman’s landmark 1993 paper documented that the momentum effect is statistically significant in equity markets. This effect holds not only for individual stocks but also at the sector level: a sector showing strong momentum is more likely to continue outperforming in the following period.
Sector rotation uses momentum signals to periodically steer a portfolio toward the strongest sectors. This strategy exploits lead-lag dynamics: once momentum builds in a sector, investors typically add to their positions gradually, sustaining the trend. Tracking the sector momentum heatmap monthly is therefore an effective way to catch rising trends early.
Focus on the green areas — these are the best-performing sectors over the last 21 days. Red areas represent weaker sectors. Click any sector to drill into its constituents: every stock is listed with its individual momentum score, so you can decide not only at the sector level but also pick the strongest names inside it.
