Model

A strategy for selecting stocks using screening criteria that have been found to work in the past.

Bid Size

The aggregate size in board lots of the most recent bid to buy a particular security.

Momentum Analysis

Usually involves looking for stocks in a strong uptrend (high relative strength), strong earnings growth, and increasing earnings forecasts. In today’s market, may include relative strength only.

Momentum Stocks

Companies currently in favor by investors (price/sales greater than 10, price/earnings greater than 35 or so).

Ask or Offer

The lowest price at which someone is willing to sell the security. When combined with the bid price information, it forms the basis of a stock quote.

Long Tail

A ‘long tail’ means the low for the day was well below the close. In other words, the market opened, sellers took over and pushed the index down, but then buyers came back in and ran the index back up to where it opened. The buyers had the last say on the day and showed a lot of strength moving up. That tends to show a reversal in the buying patterns and foretells a further rise from here for the short term.
