Depends on where you start the line!
I bought an SSR contract in 2005 for $83 and sold it in 2010 for $64. Just at first glance, that looks down to me...roughly 23% down in five years.
And most of that decline happened in the last year I owned it. Just looking quickly at the ROFR thread, the most common SSR price I see clearing ROFR is $50 per point. Even if you figure $55 as an average, that's still down an additional 14% from where I sold...less than a year ago.
I think I misunderstood Bill's point. I thought is reference to "change of policy" meant the 3/20 changes; now that I reread, I think he is talking about their change of policy towards ROFR, which has caused the prices to drop. I was only pointing out that the small sampling since 3/20 has not shown a drop off, but to your point, since they stopped effectively practicing ROFR the prices have definitely fallen quite a bit.
