REUTERS/Brendan McDermid/File Photo (Reuters) - While the pace of the global equity rally has waned in recent weeks, world shares have a better chance of climbing again if history repeats itself. MSCI’s gauge of stocks across the globe has delivered an average gain of 2.6% in the month of April in the last 19 years, the highest compared with other months of the year. It was followed by November’s 1.7% gain and July’s 1.1%, according to the data.
