Appreciate the research, Bill, but I need to point out that that doesn't really contradict my observations. I never intended to suggest any underhandedness on the part of ProShares. And I do agree that SRS, on a minute-by-minute basis, does a good job of mirroring and amplifying the moves of the IYR.
The problem is, there's a "slippage" factor in there somewhere that becomes quite obvious over time that is proving deleterious to SRS's performance over the long, and now increasingly short, term.
Yes, when IYR plunges, SRS will benefit. The problem is, you then have to be quick to take profits, for even a partial rebound may be enough to wipe out SRS's gains.
Just, as I often say at these moments, be careful. |
