Statistics Up Days vs Down Days

[earth_imperator]

Can a kind soul please post statistics of up days vs down days for SPX, TSLA, and AMD for 2023 and 2022 ?
Does the ratio differ significantly from the statistical expectancy of about same value for both sides, ie. around 126 annually?

I can quickly compute this for you for the e-mini S&P 500 index if that should suffice. Come to think of it, I may have this data for SPX as well, but ES should be close enough and that's what I have set up currently.

To be clear, by Up/Down day you're referring to net positive/negative change? An Up Day to me is something different within my trading model, but I'd assume most people associate that with a positive net change.

YES;
that'$ the common meaning yesterday'$ close to today'$ close.
Some including me, also measure it from todays open to todays close.
