This study develops and tests hypotheses that individual characteristi
cs and institutional resources influence the information sources and c
ommunication channels that securities analysts use and also influence
the analysts' outcomes, and that use of these sources and channels inf
luences the outcomes of analysts' activities. The data for this study
were collected through a telephone survey administered to a random sam
ple of 100 securities analysts from 40 of the largest investment banki
ng firms in the United States and the United Kingdom. The results show
that individual characteristics have little influence on the informat
ion sources and communication channels used by analysts, but instituti
onal resources significantly influence the information sources and com
munication channels analysts use, and also directly influence outcomes
. The paper ends with implications for information science professiona
ls.
