Analysts Sprenger and Welpe looks at the effects of microblogging on stock prices:
“They compared the “sentiment, message volume, and level of agreement” of tweets with various market indicators. ”Users who provide above-average investment advice are retweeted (i.e., quoted) more often, have more followers and are thus given a greater share of voice in microblogging forums,” the authors write.”
