Not enough constituents to compute concentration.
Insufficient bar history to compute breadth for this industry.
As of May 21, 2026, the business services industry is ranked #5 of 49by 3-month relative strength versus the S&P 500. It is currently outperforming the market, with an excess return of +14.27% over the past 63 trading days.
The 1-month rank is #7, the 6-month rank is #31, and the 1-year rank is #0. Compare these to spot a rotation: a falling 6M rank with a rising 1M rank tells you the industry is turning — money is starting to come back.
The 244 constituents are ranked by relative strength above. See the full constituents table for per-name RS.
How many stocks are in this industry?
244 core-list common stocks and ADRs. We include only names with enough trading history to compute relative strength.
What GICS sector is this in?
Industrials. FF49 and GICS are different taxonomies; the mapping is a rough one-to-many — see the siblings card for other FF49 industries in the same GICS sector.
How is the RS number computed?
We take the constituent log-returns over the lookback window, subtract SPY's log-return over the same window, and aggregate on a market-cap-weighted basis. The result is “excess return vs the market.”
Business Services is one of 49 industries in the Fama-French taxonomy. SIC code-based classification published monthly by Ken French at Dartmouth. The FF49 groupings are intentionally coarser than GICS or SIC alone — useful for market-rotation reads, less useful for fine-grained screening.
