Daily variation in the total number of words in each issue of the Financial Times between 2 nd . We find significant differences in the length of the Financial Times on different days of the week (median of the number of total words for the given weekday: Monday, 134768.5; Tuesday, 112279; Wednesday, 112536; Thursday, 116690; Friday, 111663; Saturday, 195492; ? 2 = , df = 5, p < 0.001, Kruskal-Wallis rank sum test). Significantly longer issues are produced on Saturdays in comparison to the rest of the week (all Ws > 128,000, all ps < 0.001, pairwise Wilcoxon rank sum tests with Bonferroni corrected ? = 0.0033) and issues on Mondays are significantly longer than issues on Tuesday to Friday (all Ws > 111,000, all ps < 0.001, pairwise Wilcoxon rank sum tests with Bonferroni corrected ? = 0.0033). We find no evidence that the length of issues varies between Tuesday to Friday (all Ws < 100,000, all ps > 0.01, pairwise Wilcoxon rank sum tests with Bonferroni corrected ? = 0.0033).

As a greater number of trading is known to be synchronised that have higher motions about cost of a good organization’s stock, it might be practical can be expected the connection between reports and you may natural go back to end up being much like the relationship we discover anywhere between reports and you will transaction volume

I examine whether there is certainly an equivalent link between the brand new every single day level of says out-of a organization’s title and also the day-after-day natural get back of your associated organization’s holds. The absolute go back implies simply how much an inventory rate has evolved, irrespective of the guidelines.

We browse the new relationship ranging from every day says out-of a company’s term and you can deal amounts into associated businesses inventory within more date lags. We calculate correlations between the daily amount of mentions away from a beneficial company’s identity while the every single day transaction regularity for a company from three days beforehand (indicated because ?step 3 with the x-axis) to 3 weeks later on (shown as 3 towards the x-axis). We discover you to relationship coefficients getting every single day exchange frequency eventually till the development (?1) and on a similar date because information (0) are notably more than no (slowdown ?1: W = 373, p = 0.014; lag 0: W = 362, p = 0.026, Wilcoxon signed rank screening). Put another way, a greater number of states off a company throughout the Financial Moments resembles an increased transaction volume having an effective businesses brings on the same go out and on the previous date. We find no significant relationship involving the day-after-day level of says off a good organizations name regarding the Economic Times and you may deal volume https://www.datingranking.net/local-hookup/london any kind of time other slowdown (lag ?3: W = 270, p = 0.666; slowdown ?2: W = 301, p = 0.299; slowdown step one: W = 317, p = 0.176; lag 2: W = 307, p = 0.248; lag step three: W = 298, p = 0.327; Wilcoxon finalized score assessment).

To increase the level of news data available for our study, i influence popular different brand new names of the companies regarding the DJIA. We recovered the labels familiar with identify the firms toward Wikipedia page to the twenty-first . In which symbols particularly “?” take place in these types of quick names, we delete the brand new symbol and you may replace it which have a space, when we realize that which increases the quantity of moves having the name in the Economic Moments corpus. The final set of small names utilized is provided with in the Desk S1 throughout the Secondary Guidance .
