I chanced upon this piece of statistics when reading my daily CNBC email.
Inside, there is an excerpt regarding how the US stock market reacted towards bad news such as the potential Greece failure.
The link to the whole news is HERE
What this means is:
1) Should the market (Indexes like S&P500 or Nasdaq) fall 2.4% or more
2) Within 1 trading day - especially after a market-shocking-event
3) It will recover over an average of 14days
Possible Action to Take:
1) Should the market during an intra-day trading period fall more than 2.4%,
2) A possible may be taken where you buy the index and hold it for 14days
3) Upside includes the 2.4% (or more if you bought at a lower point) in 14days .......
