This data item is calculated as the sum of strong buy/buy recommendations divided by the total number of recommendations for the stock.
Stock brokers regularly put out their recommendations about particular stocks. These recommendations could be either strong buy, buy, hold, sell, or strong sell. Each broker covering the stock will usually have one of these recommendations for that stock.
Suppose 10 brokers are covering Maruti Suzuki; 3 have strong buy recommendations, 2 have a buy recommendation, 1 has hold, and the rest have sell recommendations. Percentage buy recommendation is calculated as (3+2) / 10 = 50% .
The number above 50% is good because more brokers have strong buy/buy recommendations for the stock compared to hold or sell. The closer the number is to 100%, the better, indicating higher confidence in the stock prospects.
