Eric Krull's Back To School Sale Data

Wanted to share an interesting discussion on IBD Live on Friday. They always have a guest on Friday and this last week was Eric Krull of The Lifecycle Trade. He discussed his evaluation of stock market rallies. He looked at rallies using IBD Rally Day, FTD, DD, etc to determine (although didn’t outline exact start/stop criteria but assumably was percent gain and loss. Grouped Indexes in categories: Whipsaws, Small Losses Or Gains (SLOGs), Money Makers and Life Changers.

He has looked at the current rally and how it compares to the averages for each of his groupings.

He’s not a doom-sayer, but is advocating being cautious given the gain and duration of the current market. Certainly can go on much further, but could also be reaching some exhaustion. We are at day 56 of the rally and that puts us at greater than about 80% of previous rallies. We hit 90% of previous rally durations at 90 days. Plus, we are headed into earnings again soon. Again, he advocates for caution and making sure your plays are well founded.

Here’s one thing I found particularly interesting. He, like many others and IBD, pay attention to the “distance” the index has moved about moving averages such as 21 or 50 sma’s. He has come up with using the 50 daily MA plus (ATR x 5.5) as a calculated line that tends to serve as a ceiling for indexes, at least the NASDAQ as in the noted graph below. Note: I did not catch the ATR duration but assumed 14 days as typical.

He extended the duration out some and gave further examples:

He stressed this is not an absolute, but when it “hits this guardrail” he is more inclined to consider hedging or taking profits. Likewise, if it pulls back from the “rail” and he’s watching a stock that is showing signs of a rally, he is more likely to be more aggressive.

Finally, he makes reference to a seasonality study he has done and refers to this time as the “Back to School Sale” time.

Short summation is that the market is often in or goes into a rally after June 1, but virtually always has corrected below the 50 DMA by September 1st. At least 26 of the last 27 years. I have not personally verified these numbers, yet. But find it interesting. His theory is that with the new batch of kids going to college, a lot of folks are tapping their investments to pay for such and that stimulates the dip. Hence teh name. We’re currently roughly 6.5% above the 50 dma, for the record.

The only thing absolute about this data is that I have not looked at the numbers specifically myself, so I am not confirming this data as absolute, just putting it out there for discussion and interest. Nor is he advocating to sell everything and hunker down. He’s urging caution and look critically at your positions as things move, and he only wants “perfect” plays for any new positions at this time. He leans towards hedging or taking profits if a position gets shaky.

IBD has segmented several of these type of discussions from IBD Live and stuck them out there as individual YouTube clips, maybe they’ll do that with this one. I just find it interesting and I appreciate playing with the data that helps provide perspective. But, as always, you do you.

Haven’t had time to check out his website, but plan to. Sure he wouldn’t mind the traffic.

So he is calculating the ATR on a yearly basis with how far it is from the 50dma?

No.

As you know, ATR is a moving average of the true range. Typically it is the average of the most recent 14 days true range. I don’t have verification of if he is using 14 or 21 or 200 or ???. Regardless, the value of the ATR is used in the formula of the current 50 dma PLUS (the ATR times 5.5).

So, making up numbers for an example, an index with the 50 dma at 100 and ATR 5 works out as:

100 + (5*5.5) = 100 + 27.5 = 127.5

I guess he could use the ATR(252) but it’s more likely he is using ATR(14) which is standard Technical Analysis value. Regardless, it is summed with the 50 value, not the difference or distance from it.

If you have further info, I’m all ears. Should I get time, thought I’d run a few trials and see. Should be a real easy thinkscript indicator to make. Everything is easy if you have time.

Ok Lake thanks. I am looking at the SPY 21 day ATR and it is sitting at .87. The 30 day ATR is at .88 The 50 day ATR is at 1.04. So doesn’t it seem strange that it would be at 5.5 for the 14?

That would line up nicely with the final, final, final tariff deadline of Aug 1. Everyone at the beach, Trump actually sticks to it and people want to lock in quickly. Hello 50dma.

Excellent post, thank you very much for the info.

The numbers he presented are NASDAQ. Regardless, 5.5 is NOT the value of ATR on any date. The 5.5 is the coefficient/factor/whatever you want to call it that he calculated that times the real ATR number plus the 50 dma value, gives the best fit line. The 14 is the number of days of True range averaged in most cases. It can be any number. It’s an X for now. ATR(X).

If you look at June 30th, the price high of the day seems to intersect his blue line. At least grossly given the level of detail. Using that to do some back-of-the-napkin calculations means:

Value of blue line = price high = 20420 = 50 dma -(ATR x 5.5)
50 dma was 18739 so solving for ATR value is (20420-18739)/5.5 = 305

Values for different ATRs on 6/30/25
ATR(14) = 260
ATR(21) = 294

Close enough for me, he seems to be using a 21 ATR value. IBD likes that number for ATR also.

Quick rough check, on 7/3 the high of the day pierces the blue line, the high was 20625 and using an ATR 21, the blue line value calculates as 20567 so that fits.

“Guard Rail” blue line = 50 DMA + (ATR(21) * 5.5)

Refreshing this good thread again, as it looks like we might be confirming it once again.

In reviewing this, it occurred to me that it does not matter what the precursor is, 26 of the last 27 years saw the markets close below the 50dma on or before 9/1.

That is not saying much this year as the S&P is only 1.8% above the 50dma and the Naz is only 2.8% above (but was 5.3% above on Thursday’s close).

14 times, or just over 50%, the table shows there was a mild correction involved, where 8.9% is the biggest decline they consider mild and 3.0% was the smallest decline in that list. Using just my eyeballs, I don’t seem to find a strong correlation between the correction staring before or after 7/15 and the resulting depth of the correction.

Does this help us? It is “Certain” that we will be below the 50dma by Sept 1, but that could mean a 2.8% decline from here, or 27% decline from here. Having a little more cash than usual might be the course to take.

Just a followup of the actual line:

Back of the napkin math suggested the ATR was a 21 line, but further eval shows he’s using the 50 to match his moving average. Chart above shows the line calculated using the 50 sma and ATR(50).

For those with TOS, this is the indicator as added to the above graph. I put in inputs to make it easy to play with variations, should you so desire.

Straight listing is: tos.mx/!xvwknKai

Use at your own enjoyment and risk. Works for me but never guaranteed.
