Never heard of the guy. Perhaps he has a track record, and he's made some good predictions. Saying that "sudden declines" will take place without giving at least a trajectory of the supposed percentage of decline is meaningless.
If an investor has held significant gains and shifts to increase the percentage of their investments in CASH, then there's always an opportunity to buy the market lower. It appears (as of today) that the S&P is on track to complete an 8 bar Fibonacci sequence on the
yearly chart at the end of 2016.
Since 2009, the market has been in a directional UP move from the bear market lows with many bull market corrections averaging 10%. That entire cycle will end with SOME type of bigger corrective pattern (i.e. a bear market correction, generally one that exceeds 20%). Those who BUY the correction and hold index funds through standard market ETFs and/or mutual funds that mirror the S&P will do quite well. Or if you're a stock picker, then just buy the stocks that have historically recovered during prior corrections by growing its earnings and paying its dividend.
"Past performance is not indicative of future results" is the slogan everyone sees on every brochure or advertisement. However, using the historical past as a guide, the U.S. stock market has eventually recovered after EVERY draw,
regardless of the reason for the draw.
So it really doesn't matter what Jajeda or anyone else says or what causes the drop, as long as you are willing to buy the dip and HOLD for the eventual recovery, even if your timing isn't perfect.
Personally, I think the S&P drops to 1,600 or thereabouts, as prior resistance will most likely serve as new support, on the bigger time frame. If the market cannot exceed and break over the 2,134 top, then it's likely that the S&P sees a 20%+ bear market correction. Even if it DOES break and hit the 2,300 level as many pundits predict, it's likely to see even a bigger correction. When that happens is anyone's guess.
Just in case, I printed out Jadeja's predictive dates so we'll see if what he says holds true.
Here's a recent graphical analysis posted by Yardeni research that shows the S&P bull and bear market corrections going back to the 1929 crash.
