both short the market 3X, but SPXU
shorts the S&P 500
shorts the Russel 200 Small Cap Index. Keep that in mind on day when the market tries to rally a little in the morning while this correction is going on due to the China-US trade war. The S&P 500
has more staying power due to the sheer size and monetary strength of some of the better known and longer standing large cap companies that keep the numbers from falling too much when they have a good day in spite of market conditions. While the small caps just take a beating; so, if your going to short the market (one of the few ways to make money right now) may as well short it for all it's worth. Just look at the difference in how much the small cap inverse ETF
is climbing....and it's made a good days profit every day but 1 since the 21st!
