Mood and the Market: Can Press Reports of Investors’ Mood Predict Stock Prices?

We examined whether press reports on the collective mood of investors can predict changes in stock prices. We collected data on the use of emotion words in newspaper reports on traders’ affect, coded these emotion words according to their location on an affective circumplex in terms of pleasantness and activation level, and created indices of collective mood for each trading day. Then, by using time series analyses, we examined whether these mood indices, depicting investors’ emotion on a given trading day, could predict the next day’s opening price of the stock market. The strongest findings showed that activated pleasant mood predicted increases in NASDAQ prices, while activated unpleasant mood predicted decreases in NASDAQ prices. We conclude that both valence and activation levels of collective mood are important in predicting trend continuation in stock prices

Effect of ionizing irradiation on the physiological activity of cyclic adenosinemonophosphate on smooth muscle preparations.

The effect of ionizing irradiation on the physiological activity of cyclic adenosine monophosphate (cAMP) in smooth muscle preparations from frog lung was studied. cAMP, given as dibutyryl salt (dib-cAMP) inhibited the radiation induced contractions of the muscle in a manner similar to the action of theophylline. In vitro irradiation of dib-cAMP resulted in an alteration of the chemical structure of this substance, i.e., formation of monobutyryl-cAMP and further derivatives as well as a decomposition of the purine structure. There was also a loss of the relaxing activity of irradiated cAMP on the muscle tone of frog lung preparations. The physiologically measured inactivation of dib-cAMP was far more pronounced than the chemical alteration. An inhibitory effect of the reaction products is postulated
