One common feature of these months is sharp declines on the stock markets.
September 2000 marked the peak of the dot-com bubble, On February 27, 2007 Shanghai Stock Exchange tumbled 9% from unexpected selloffs, triggering major drops in worldwide stock markets, July 2007 and July 2008 were both before the onset of the global financial crisis, December 2015 was the start of a volatile year for stocks, October 2018 saw a steep drop in stock prices amid trade tensions and geopolitical uncertainties, and January 2022 was a mix of Omicron and Russia’s military presence near Ukraine’s border.
Summary
While the past is not an indication of future results, it is interesting to see how the market is reacting to the current situation, look at the similarities with the past, and observe how things will unfold.
