This year's inflows into ETFs worldwide crossed the $1 trillion mark for the first time at the end of November, surpassing last year's total of $735.7 billion, according to Morningstar data. That wave of money, along with rising markets, pushed global ETF assets to nearly $9.5 trillion, more than double where the industry stood at the end of 2018.
Most of that money has gone into low-cost U.S. funds that track indexes run by Vanguard Group, $Blackrock(BLK.US)$ and $State Street(STT.US)$ which together control more than three-quarters of all U.S. ETF assets.
Technically they're not the same concept, but the $1 trillion landmarks still remind me of $Tesla(TSLA.US)$ hitting a $1 trillion market cap on Oct.25. It showed how influential the company is. 
Are you part of the one trillion? Would you tell me about the reason that you buy or not buy ETF?
