When I use Google Finance, there is a link to the stock screener to
the right of the 'search finance' button. Text is "Stock Screener
New!"
It may be in limited beta or something (if so, lucky for them!)
I should note that the screener now helpfully informs me that the
range of market caps tops out at $454 billion, and the lowest market
cap is "-9223372036.85B". I find this hard to imagine, unless the US
Government went public without telling me. The screener's default
settings now yield the following results:
Company Name Symbol
PowerShares Lux Nanotech (ETF) PXN
Calamos Global Dynamic Income Fund CHW
SPDR S&P Homebuilders (ETF) XHB
SPDR S&P Biotech (ETF) XBI
SPDR S&P Semiconductor (ETF) XSD
First Trust NASDAQ Clean Edge US (ETF) QCLN
So maybe they're still improving it.
