How come some indexes have no volume? For example, $BKX Bank Index - Philadelphia, $BTK Biotech Index and $INX Internet Index. Can you trade these indexes?
Second question, how can you tell what stock is related to a particular index. Is there a database that lists stocks and the indexes they are most closely aligned with?
Generally prefer indexes with volume, bid /ask spread;
$XAU is an exception. Hard to trade wihout bid-ask & volume.
BBH index some trade;
HHH may be a bit low volume to trade,and both have stock options.
yahoo.com has some index info.
Think Merril Lynch nicknamed them ''holders'' , like RKH,BBH,HHH.
