Forex

is an advance or decline line of the
15 most active stocks on the New York Stock Exchange. They are listed
daily in many newspapers. Several large capitalization stocks, such as IBM,
frequently appear on this list. Other stocks make the list only when they
catch the publics eye due to an extremely positive or negative piece of
news. MAS is a big money indicator - it shows whether big money is bullish
or bearish.
MAS for each day equals the number of the most active stocks that
advanced minus the number of the most active stocks that declined. For
example, if 9 of the most active stocks went up, 4 fell, and 2 were
unchanged, then MAS for that day is 5 (9 - 4). Each day's MAS is added to
the previous day's total, creating a cumulative MAS line.
When MAS moves in the same direction as the broad stock market, it
shows that big money supports the trend and it is likely to continue. When
the market goes one way and MAS goes the other way, it shows that big
money is betting on a reversal. When the trend of MAS diverges from the
price trend, the market is especially likely to reverse.
