With prices at their current, stagnant highs, it takes a very wide perspective to see the possible outcomes, so we take a look at the monthly chart for the S&P 500 with the Euro and Dollar ( DX1! ) overlayed in white and green, respectively.
The current number of interest is, of course, 2100.00. Below that is 1800.00, which has served as the base of current price since late 2014. While it is to be expected that buyers will engage if such prices are reached, the monthly chart sells us that we've been there, done that- once in 2014 and twice this year already. Because we've already seen significant buying around 1800.00, that price can be considered "exhausted;" buyers have seen it work too many times and will be expecting a cheaper entry to reduce risk.
That leaves us with two more numbers below:
-1685.75, the last notable price that caused significant selling
-1468.00, a price that has been sold and bought en masse in every market cycle thus far going back to 1998.
1468.00 would be the ultimate destination for a large correction the S&P , as it would satisfy the new monthly trend that began in 2009 following 2008's massive correction.
The timing of this potential correction is, at this stage, pure speculation as the geo-economic/political factors that catalyze these events are far too many. Nonetheless, any major correction can either save you a small fortune or make you a large one with proper planning and execution- Just as George Soros planned to "break" the Bank of England after his analysis.
