So Much for the Experts

[marko]

Back in January when the market was on fire, I saved the following CNBC article and set my calendar to check back on it today.

In short it says that: "...When January is higher, the final 11 months rise by an average of 12 percent, according to Detrick's calculations. When the S&P 500's gains are 5 percent or more, as it is tracking this year, the final 11 months surged an average 16 percent...."

With 6 weeks left in the year, I think I can safely say 'that ain't gonna happen'.

So, another 'expert' who's calculations and charts didn't mean a thing.

FWIW

There are so many market gimmicks. Wish the talking heads presented them as such. The best use of “historical” observation is how FireCalc does it.

Yeah it’s like rattling off sports statistics. Mostly a time filler, but announcers love to look smart and sound important.......

That is interesting everyone has their prediction and that is all they are is a guess. Thanks

 

[MarieIG]

Watched it. Made me think of the caveat, past performance is no guarantee of future returns.

So we can expect a huuuge rally, right?

And as with sports, someone will add a qualifying statistic to prove the theory, like “except in years where the dollar fell and the first snowfall north of the Mason-Dixon line happened on November 1...”

I wonder if the positive prediction and negative prediction accuracy %'s are similar?

Fun to look back, thanks.

And yet, a poster on this forum is giving great weight to some statistic about gains in the market after a midterm election (1st term midterm?). Or was that "1st term midterm in years where the dollar fell and the first snowfall north of the Mason-Dixon line happened on November 1...”"? <credit to BWE in previous post>

The big deadly fire in California jinxed everything. All that historical statistics thrown out the door.

Sell, sell, sell...

Unfortunately home builder business has been dropping due to higher rates. Not sure if California can counteract.

There is a recent pop up, but small compare to the larger drop.

The thing about averages is that they don't tell you very much about the underlying data. How many data points does he have, and what is the shape of the curve and how thick are the tails? What if this has happened four times before and the two outcomes were increases of 1%, 2%, 22%, 23% ... it's completely true that the average increase in this made up scenario is 12%, but I'll bet you don't think that's the most likely outcome.

Not sure why, but whenever I see a question / answer about a stock market forecast, this clip always comes to mind

Maybe you missed the word "average"?

I'll bet adding this year's data to the mix doesn't move the average much, if at all.

That one bothered me because it was very specific about the span of time in those specific few years...the measurement was 6 or so months after the election. What about 4 or 8 months? I wonder. If you have 18 data points selected from a possible 1000, you're bound to find a pattern if you check them all. And it holds true until it doesn't.
