Ultra Short ETFs Benefit From Volatile Market

Are there any ultra-long bond ETFs?|

Ultrashort ETFs Can Work if You Trade Them Correctly

"from the data presented above is that a bearish investor, betting against a major market average like the S&P 500 or the NASDAQ 100, could indeed have held the corresponding UltraShort ETF and realized a quite reasonable gain over the course of the last 12 months."
This is absurd. His own stats disprove it. IYF was down 75.4%. By arbitraging with SKF, you would have needed + 150.8%; instead you got + 82.8%, i.e., SKF fell behind by 68 percentage points? Tracking error, anyone?

The Hidden Cost in Inverse ETFs

"short the SDS and long the IVV. While this is not a risk free arbitrage (unexpectedly low daily volatility could lead to the opposite effect), in the current market this doesn’t seem likely."
This is not arbitrage but doubling up: short SDS is effectively double long + long IVV is another long.
