The thread was basically saying that you couldve had a better return putting your money into High-yield savings accounts, Series I savings bonds, Short-term certificates of deposit than nphc. But that was wrong as i will show below.
The time frame was 4 years ago from someone else in the same conversation talking about not buying nphc which i clearly showed from this chart below that you wouldve made so much more money buying nphc at that time and selling when it went up on two different occasions. Even if you missed the first run, you couldve traded on the second higher run. Having your money in some small interest rate bank earning tiny amounts of interest calculating in inflation means you would have hardly earned anything.
Inflation does not devalue your money anywhere close to the rate of NPHC the last 2 years.
