At the B&N on Market Street in Philly
July 29, 2021 | Leave a Comment
at the B&N on Market Street in Philadelphia which i visited over the weekend, i explored the business section to augment my recap of chapter 6 of Quixote. i found all the finance books to be about panic or the decline of capitalism or the need for regulation to reign enterprise in, except for a book by ellis which, like all the other finance books, espoused the out-of-place-and-time methods of the Sage and his philandering mentor.
i bought a big selection of them but the fire department picked me up for unsteady walking. (i wasn't wearing shoes and had my sneakers in my book bag so i fell.) and i left my books on a bike and they were stolen within 5 minutes which made my story seem not valid.
thus i can't relate to all the titles that espoused the graham & dodd, sage line, or the hoped for destruction of capitalism.

Dr. Brett’s work
July 28, 2021 | Leave a Comment
i recommend Brett Steenbarger's book The Psychology of Trading. it contains all sorts of fixes for emotional trading and reads like a mystery novel.
Brett's book is like a Paul Harvey story. it starts with a life or death situation from his counseling. then it shows how he solved the problem by applying trading wisdom.
i like his technique of talking out all your trades — and moving away from the market when it's going in your favor. also, all the wise words about the function of markets

The state of analytics
July 28, 2021 | Leave a Comment
good article on what is ruining baseball and why the Yankees lose so much when ahead and turn to analytics. they don't take account of ever-changing cycles and rely on one metric rather than the panoply.

Hedging the inventory, from James Lackey
July 28, 2021 | Leave a Comment
Someone said there is no way to hedge this, and I said why not sell some used car companies stocks just in case and….
A reader writes:
Yes, the difficult question is to find the correlation between the used car inventory and hence their aggregate values with the used car sellers' stock prices. I don't know which publicly trade companies only sell used cars. Once one knows the equivalent delta value of the inventory, then one can hedge the delta risk using various strategies as you have suggested.
James Lackey writes:
After a day, I think of ways I could as a day trader blow this trade up. The risk is car prices crash as they should and the used car big box store's stock goes up big on a squeeze. Therefore the way to protect that is to buy call options. Buying options is not businesslike as the vigorish is unbusinesslike. I do believe others must be in this trade as I'm always the last to know. I'm sure I'm not the only guy that thought of this trade. Yet so far the dealers and the vampire squid isn't pitching this trade.
Someone said to me there is no way to hedge this book. I laughed and called bs and said there is.always a way. Problem is the cost.
Duncan Coker writes:
The only part of Dalio's book I found readable was the first section where he
talked about his early consulting work prior to Bridgewater. One of his first
major accounts, McDonalds, needed to hedge chickens. Dalio came up with an
elegant solution with ratios of feed, energy and land. Futures were not a
ubiquitous as they are today and his ideas were quite good.
A reader adds:
Jake Powell also commented on the recent high prices of used cars shall come to pass in his congressional testimony this morning. Similar to the Dalio methodology, then perhaps auto parts stores like ORLY an/or AAP could be affected then.

Charles E. Sorenson, from Jeffrey Rollert
July 28, 2021 | Leave a Comment
I’ve been reading up about Charles E. Sorenson as someone who I missed on his contribution to Ford. There’s a lot of lessons in/on his life. One is, the #2 defines the #1 man much more than is commonly assumed.
As you would expect, I discovered him through his boat.
Bud Conrad writes:
Fantastic photography, especially obviously surreptitiously boarding the Helene and the waterways around.
I have often been captured by the faded grandeur of some of Detroit, and this is magnificent. I am also shocked by the abject destruction of many areas and buildings that show an ugly turn for humanity.
I wonder how this happens in America, as I live in ever-changing Silicon Valley; where for example Robert Noyce's house (Inventor of integrated circuits and founder of Intel) with 4 acres, two lakes and vineyard sold for $11.4 million last month. My worry is that Detroit may be the model of future USA. San Fran ain't what it was to the flower children of the 60's.
Silicon Valley pioneer’s former home expected to sell for $14 million. Take a look

The Duckworth-Tukey test
July 25, 2021 | Leave a Comment
the duckworth-tukey test for differences between medians is useful and interesting and novel. i will give an example later. test 93 from 100 Statistical Tests by Gopal K. Kanji is unusual, useful for testing diffs between medians. consider the smallest observation from one distribution and the largest observation from the other. then take the overlaps
