I have more examples on limitation of screeners adding to what I shared in sg mart thread
In december 2025, promoter had pledged roughly 5% of shares with mcx for hedging purpose. Exchanges wrongly reported this as stake sale. Out of the blue all screener tools started reporting 96% of shares as pledged. Even today screener shows 6% shares as plegded and stake sale of 5%. Both of these claims are denied by the promoter. While some small portion was sold in March for personal use, it is nowhere near the 5% being reported. I have already shared my views on book value being severly depressed. Imagine owning ~14 acres of land near Hyderabad and accounting it at 29 cr only. I am pointing these things out because I used to blindly apply pledged percentage = 0 query condition while filtering stocks in screener. And unless some analyst clarifies this in concall, AI would miss it as well.
While BIL themselves are at fault for above misunderstandings, bottomline remains that screeners are not reliable way to filter stocks.
