Through President of the United States, Bloomberg News and Statistical significance
Bloomberg News observed Volfefe was created due to the statistical significance of Trump tweets on bond prices. ABC News Online posited Volfefe could help analyze interest rate risk in the face of "unpredictable" activity on social media by Trump.
Etymology
The name "Volfefe" is a portmanteau of the words volatility and covfefe, the latter being a word (widely presumed to be a typographical error) posted in a 2017 tweet by Trump.

Creation
Volfefe was launched by JPMorgan Chase on September 9, 2019.
Methods
In forming the basis of the methodology behind Volfefe, JPMorgan Chase used software to analyse the corpus of Trump's tweets. 14,000 tweets were used in the analysis to form the initial projections for their software. Their analysts determined that there were direct correlations between tweets and subsequent market movements. These market movements were most notably evidenced when the tweet specifically references financial matters including the US Federal Reserve. The tweets issued during the working day of the New York Stock Exchange were more likely to cause a change in market sentiment; however, it was noted that the tweets can come at any time of day and thus have an effect on markets around the world. Key words in tweets include "China", "billion", "products", "Democrats", "great", "dollars", "tariffs" and "trade".
Analysis
Bloomberg News noted, "JPMorgan’s 'Volfefe Index,' named after Trump’s mysterious covfefe tweet from May 2017, suggests that the president’s electronic musings are having a statistically significant impact on Treasury yields."
ABC News Online commented JP Morgan created Volfefe, "to measure how much impact Mr Trump's unpredictable tweets have on US interest rates".
