How much would you need to get in the future to pay $1 now?...

How much would you need to get in the future to pay $1 now? Let's assume 12 months, just for the heck of it

So one year from now, what return would be acceptable for you?
Would you be happy with $1.05 (5% interest)
How about $1.10 (10% interest)
How about $1.20 (20% interest)

What would you get from the bank? Or better yet, what is the current market risk-free rate?? Does it compare? I don't think it does

Or are you suggesting a year from now ISX won't be worth above $1.01 (the current basis of the market risk-free rate of 0.96%), because that is the argument you are trying to make

Don't assume all people on HC is an idiot, there are some that actually know what they are doing
