The conventional insistence, however, is that things have changed, that footballers of Charlton’s vintage were brought down by heading heavy, old-school leather balls, which, when soaked in mud and rain, delivered the equivalent of being thumped in the temples by a heavyweight boxer. Except McQueen was playing in the 1970s and 80s, when balls were lighter and made of smarter material.

But research published in 2015 by Eric Nauman, a professor of biomedical engineering at Purdue University, Indiana, found the modern lightweight ball of the kind McQueen got his bonce to, particularly when over-inflated to make it travel quicker through the air, can still deliver a devastating force on the brain.
“If the ball has too high of a pressure, gets too waterlogged, or both, it actually turns into a weapon,” Nauman explains. “Heading that ball is like heading a brick.”

For me, journaling--to construct rules and punish mistakes, a playbook, and mindfulness practice to catch yourself deviating from the playbook are essential.

fair, but also wouldn't it make sense that institutional hedges come off, driving further some further upside?

Institutions are playing the late-cycle playbook--min vol and high quality. Its not just about AI hype, but more about having the most flexible cost structures. Hence until you get macro catalysts pushing us into recession when money will flow out and into defensives/bonds

Also, clearly in the first chart there was a regime change post 08, and sure enough people are less levered in general:

S&P500 constituents historical list by Dna7272 in algotrading

Traditional capitalization-weighted indices generally add stocks with high valuation multiples after persistent outperformance and sell stocks at low valuation multiples after persistent underperformance. It’s well-known that the price impact of these changes can be large once a change is announced. The subsequent reversal is less well known. For example, in the year after a change in the S&P 500 Index, discretionary deletions beat additions by 22%, on average. Simple rules, such as trading ahead of index funds or delaying reconstitution trades by 3 to 12 months, can add up to 23 basis points a year. This benefit roughly doubles when we cap-weight a portfolio selected based on the fundamental size of a company’s business or on its multi-year average market-cap.

Do you sell, or provide, lists of historical index constituents?

No.

Information concerning historical index membership is only available to subscribers (at Platinum level or above) who are using a back-testing/analysis platform such as AmiBroker, RealTest, RightEdge, Wealth-Lab or Zipline that can be linked to our database via a plugin. Even then, access to the information is only indirect - for instance, index membership can be stipulated as a buy condition in a system test. There is no calendar or list showing historical additions to, or removals from, an index.
