Is there a hard threshold? Do high risk investments such as penny stocks qualify as gambling? Do low risk investments? Annuities? Bonds? CDs?
This comment got me wondering.
Is it more to do with the venue? Stock markets and real estate vs casinos and the lottery?
Were the MIT Blackjack Team gambling or investing?
Is this just another semantic hotdogs are sandwiches discussion or is there an agreed threshold?
The key phrase is ‘over the long run’ and ‘holding them for years’. That 90yo wants to have long-ago moved their investments into bonds because, as you point out, a stock market downturn may not come back up before they die. Waiting out a downturn takes years and they are drawing down on their investments regularly.
