what stats are kept for each stock

For each stock, the most common stats kept are price, volume, market cap, valuation ratios, earnings, and dividend data.

Common stock stats

• Open, high, low, close.
• Volume and average volume.
• Market capitalization and shares outstanding.
• P/E ratio, P/B ratio, PEG ratio, and price-to-cash-flow.
• EPS, revenue, and profit-related figures.
• 52-week high and 52-week low.
• Dividend per share and dividend yield.
• Float and institutional ownership.
• Some platforms also track technical indicators and trading activity metrics.

Practical view

If you mean the stats most apps show on a stock page, the short list is usually open, volume, 52-week range, P/E, EPS, dividend, and market cap. If you mean deeper research data, analysts also keep revenue, net income, balance-sheet ratios, and cash-flow measures.

Example

For a stock like Apple, a typical summary might include:

1. Price and daily change.
2. Volume and average volume.
3. P/E ratio and EPS.
4. Market cap and shares outstanding.
5. Dividend yield and 52-week range.

The exact set varies by site, but those are the standard stats most investors and stock apps keep.
