from 3xetf.com:

Direxion S&P 500 Bull 3x ETF SPXL $107.75 (-1.06%) 1,132,270
Direxion S&P 500 Bear 3x ETF SPXS $10.80 (+1.03%)

4,116,600

 

ProShares UltraPro S&P500 Bull 3x ETF UPRO $81.78 (-1.03%) 2,626,530
ProShares UltraPro S&P500 Bear 3x ETF SPXU $20.41 (+0.94%) 4,436,000

 

Any reason you trade SPXL/SPXU pair (different company etfs), not SPXL/SPXS or UPRO/SPXU pair?
