US stock market rebounds ahead of election day?? I was not expecting this, anyone care to share their thoughts on what led to an increase in investor confidence during this volatile period?

Its not always about investor's confidence that drives the market and sometimes it can be greed as well. The only thing we can agree on is that there is increased volatility and potentially higher trade volume during this period. Not to mention that swing traders will also push the market in either direction as well. So in short, the rebound does not necessarily mean a state of recovery.

The strong distrust in banks and us governance which might result in citizens deciding that that putting their money in the market is the best way to safe guard their wealth.

The stock market is not reflective of current economy. The stock market being bullish reflects confidence after the election which might be because there is a historical correlation between the party in congress and index funds performance. Regardless of the party in congress, president, senate, index funds still performed after the election in the last few decades
