Batch download for market cap?

[cheungcn]

Is there a way to batch download the market caps of a number of stock?

If I do it one by one, yahoo starts to limit my call to a snail pace.

Or anyone can suggest where can I find a list with market cap for US stocks?

yahooquery retrieves fundamentals much faster. Probably yfinance can be improved to match, but their codebase is complex, hard to figure out what they do.
