A single block trade is calculated as a trade that is greater than or equal to 10,000 shares. The block trades screener gauges institutional sentiment for stocks. The net cash flow is calculated as the composite dollar value of buy side block trades minus the dollar value of sell side block trades. The bought/sold ratio reflects the volume of block shares that were traded on the buy side relative to the volume of block shares that were traded on the sell side. Figures are updated every 5 minutes between 9:30AM and 4:00PM EST.
