I saw an ad on youtube for a stock trading course that gives you stocks on certain days that have a 10 year history of going up on that day or over the course of a week or whatever. It struck me as curious because they actually gave some examples on the ad. I visited the website (super salesy), and watched a video of theirs where they gave more (the same?) examples. Apparently certain stocks go up every point on the same day each year, and if this has happened for the last 10 years, they get included on their list. Some of the examples they gave: Adobe on december 20th Intuit on february 8th thermofisher on november 13 Is this just market almanac stuff? Seems they use options because the percentage values were in the hundreds, and when I checked one of these stocks, it did not go up 300% in december. This is run by Tom Bubsy and Roger Scott who say they were hedge fund managers and did some bragging in the video. Was very sales. If you have a winning system you use it, you don't sell it. Or it was just a bull market for the last 10 years so of course they go up. Thoughts on this kind of trading system?
Another variation on the tired old seasonal almanac imo. But, prove me wrong. IMO you'd find much richer fishing grounds with inter market correlations.
Probably just over fitted. They’ll show ones that have gone up for past 10 years, go back last year, check the ones that have gone up every time in 9 years then see how they perform the next.
Bernstein's seasonal dates were at least based on sound fundamentals (planting, harvesting, etc...), not mindless data mining.
There is nothing new to that. Each industry has its business cycle where it earns a lot of monies and where business is slow. So, what these guys do is look back at the history of say XYZ. Now, XYZ sells say tires and around October and November of most years, it is busy and earnings go thru the roof. So, they recommend buying XYZ say October 1 and holding till November 30. Then, sell it and get out of the stock after. Now, nothing is 100% so, if that earnings pattern for this stock has happened say 8 out of the last 10 years then, that would be a very good reason to use the pattern and trade it.
This was a really long time ago, in the early '90's when Bernstein had late night infomercials all over TV about Moms and Truck Drivers placing futures orders according to Bernstein's Seasonals and then going about their daily lives. He quit with the infomercials after the WSJ article.
