Just to further Chipleigh's elegant response, gambling has a time frame when to call, show, throw in whatever game you have that will have results in usually 20 minutes maximum.

Sorry to digress, but in microeconomics you would consider the amount of choice, time, risk and limitations that would be needed to meet the definition of 'gambling', backed up by lots of data.

With investing, you only lose if you sell at a loss. You can sell in many points in time, but to compare it to gambling, investing is like playing a hand of poker that is never ending until you decide to fold. It is extremely rare that the house (company) folds before you, unless in the rare case it does go bankrupt (delisted) and that assumes you haven't cared or followed news of it for you to sell until it gets delisted or bankrupt.

I am a FA guy cause I don't want my investments to die. I like underdogs and there is risk involved, but it ain't gambling mate, because if it was, I would lose every time (I have zero luck in any form of gambling), but I do consider myself as a competent investor.
