A small thread on the importance of using log charts:

Rs 100 of 1990 is not comparable with Rs 100 of 2021 in absolute terms

Similarly, price of a stock some years back may not be comparable with today's price in absolute terms.
For EG, SBI quoting at Rs 10 in 2002 is not comparable with SBI quoting at Rs 400 now

For a 100% jump in 2002, stock would have to reach 20 (which is just Rs 10 in absolute terms)

While today, Rs 10 in absolute terms is a meagre 2-3% move
We shall always calculate moves in % terms

For this reason it's preferred to use log charts, especially long term charts

Log charts calculate moves in % terms
Also, if a stock goes from 20 to 200 in one year, even then it's preferred to use log charts.

Great article from @AsheSchow. I lived thru the 'Satanic Panic' of the 1980's/early 1990's asking myself "Has eveyrbody lost their GODDAMN MINDS?!"


The 3 big things that made the 1980's/early 1990's surreal for me.

1) Satanic Panic - satanism in the day cares ahhhh!

2) "Repressed memory" syndrome

3) Facilitated Communication [FC]

All 3 led to massive abuse.

"Therapists" -and I use the term to describe these quacks loosely - would hypnotize people & convince they they were 'reliving' past memories of Mom & Dad killing babies in Satanic rituals in the basement while they were growing up.

Other 'therapists' would badger kids until they invented stories about watching alligators eat babies dropped into a lake from a hot air balloon. Kids would deny anything happened for hours until the therapist 'broke through' and 'found' the 'truth'.

FC was a movement that started with the claim severely handicapped individuals were able to 'type' legible sentences & communicate if a 'helper' guided their hands over a keyboard.
