Ridiculously easy way to get the spend $200 million trophy/achiev

Haven't seen it on here and people seem to believe if you've beat the game and missed out on waiting for the assassination missions you won't be able to rack up 200mil to get the achievement. It says spend 200million, not earn 200million. All you have to do is do the final heist(technically you can do it with any amount of money even 1 dollar but that'd be unheard of) go to the stock market, invest 20mil or so into any stock and then immediately sell it(you'll neither gain nor lose any money) then buy it again If you are spending 20mil at a time then doing it 10 times will get you the achievement and you'll still have your 20million.
