Missing values are empty cells. Companies with no XBRL report carry no fundamentals, and P/E is empty when earnings are not positive. Trailing figures are empty across an IAS 29 inflation restatement, so the dollar growth columns are the comparable ones. Market segment is empty before late 2019, when the exchange grouped shares into lists A to D. Eight ex-dates without an exchange notice stay unadjusted. Two companies state no line of business, so they carry no labels.

• Screens mixing momentum, valuation, profitability and balance sheet strength
• Returns and risk measured in dollars as well as lira
• Finding companies by sector, index, owner, export reach or what they disclosed
