How this data is sourced

Headline figures (revenue, profit, EPS) are scraped from the PSX company page; full income, balance-sheet & cash-flow detail from stockanalysis.com; and equity, asset & dividend lines from PSX Analysis Reports. It refreshes on a rolling schedule: PSX figures hourly, full statements nightly (the whole market is cycled about every 2 weeks) and Analysis Reports weekly. When a company files a new annual/quarterly report, its headline numbers appear within hours and the full statement within ~2 weeks, after which every derived ratio recomputes automatically each night. The TTM column sums the last four quarters for income & cash-flow items and uses the latest quarter for balance-sheet items (shown as Latest Q).

How these ratios are calculated

Every ratio is computed by FinVision, not scraped. Profitability, liquidity, leverage & growth ratios are derived from each year's reported financial statements (same source as the Statements tab: PSX + stockanalysis.com). Valuation ratios (P/E, P/B, P/S, EV/EBITDA, Dividend Yield) need a share price: the latest year uses the live/TTM price (updates ~8 min), while earlier years use each fiscal-year-end price from stockanalysis.com. All statement-based ratios recompute automatically each night (04:30) as new figures arrive, so a newly filed report shows up within hours (headline) to ~2 weeks (full detail), then flows straight into these ratios. The TTM column uses trailing-twelve-month income (last 4 quarters) with the latest-quarter balance sheet, and live prices for valuation.
