PickStock (copyright 2003, Bell Software and Services,
Inc.) uses principal components analysis to search out
potentially underpriced stocks by analyzing a user-
supplied database of historical stock prices. The
program postulates that a given vector of prices (for
example, today's price for a set of stocks) can be
explained by a linear combination of underlying
economic components. Who can best make use of this
application:
It is hoped that any user who can download stock price
data into MetaStock text format will find PickStock
sufficiently easy to use. Facility in handling text
files and importing them into spreadsheets is also a
plus. Economists and stock analysts may be able to
utilize the program along with a more traditional
analysis of economic fundamentals. Scientists,
engineers, and students may even be able to tap into
the powerful principal components analysis engine that
PickStock incorporates by replacing closing prices
with arbitrary data (ie. a given 'date' can be
associated with one experiment having outputs for each
of the 'tickers' with the output values corresponding
to the ticker being in the 'close' field).
