And I would also encourage everyone to look at a year to year basis -- not a month to month, just because of how the strategy works. The hedges have to both kick in and be paid for.
The "worst" case for the strategy is about a 7% SPY drawdown right after opening a new year strategy. At that point you've not paid for the hedge at all, plus you've lost some on the diagonal, and as the hedge doesn't really start until a 5% drawdown, then you haven't gotten the advantage of having it.
On a 12 month rolling basis, it works great (except for one period due to an odd mix of market crash plus volatility dropping, but we did address that).
Anchor ideally outperforms in up markets (those up over 10%) and in crashes (over 15% to 20%). In flat markets (5% to -5%) we EXPECT to underperform. In small down markets (-5% to -10%) it's a tossup depending on a lot of factors if we outperform or over perform.
