The Cost of Free Data: Why Use Premium Stock Prices?

Quandl has always prided itself on making financial and economic data accessible to all investors. This is why a number of our datasets are free resources, like the Federal Reserve Economic Data (FRED) and US Energy Information Administration Data (EIA).

Analyst expectations were much milder at a loss of 36 cents per share on $314.06 million in revenue. GoPro cited production issues as the cause for both the third quarter miss and the guidance for Q4. Prior to the earnings announcement, most pundits were bullish – or at least neutral –  on GoPro: see MarketWatch coverage, AmigoBulls, and this note from Raymond James. This is...
