Sorry I know this is slightly off topic:
Is it a steal to purchase them now or should I give it more time? I can buy most stocks at around a 10% discount

I was thinking of using the Robinhood app since they dont' charge fees and do like $100 a month for long term retirement investment. Dollar cost averaging.
Or is it a gigantic bubble about to burst again? I got burned bad in late nineties when bubble burst!
