1. You purchase 100 shares of DUST @ 2.00 share. Prin investment of $200
2. Day 1, Dust drops 12% due to 4% drop in NYSE Arca Gold Miners Index (lets say drop from 100 to 96). Thereore your new principle balance is $176.00
3. Day 2, in order to recoup your 12% loss you need NYSE Arca Gold Miners Index to increase 4.55% or 4.368 points in one day to recoup your losses.
Hence, if you catch a falling knife in these 3x daily etfs, this decay will eat you alive....
