Clarify on some Stocks Terminology
Volume is measured in the number of shares traded in a given day, week, month, etc. This means that it's not necessarily a directly-comparable measure between stocks, as there's a large difference between 1 million shares traded of a $1 stock ($1 million total) and 1 million shares traded of a $1000 stock ($1 billion total). Volume as a number on its own is lacking in context; it often makes more sense to look at it as an overall dollar amount (as in the parentheses above) or as a fraction of the total number of shares in the marketplace. When you see a price quoted for a particular ticker symbol, whether online, or on TV, or elsewhere, that price is typically the price of the last trade that executed for that security. A good proxy for the current fair price of an asset is what someone else paid for it in the recent past (as long as it wasn't too long ago!). So, when you see a quote labeled "15.5K @ $60.00", that means that the last trade on that security, which the service is using to quote the security's price, was for 15500 shares at a price of $60 per share. Your guess is correct. The term "institutional investor" often is meant to include many types of institutions that would control large sums of money. This includes large banks, insurance companies, pooled retirement funds, hedge funds, and so on.
