My broker failed to maintain adequate inventory of ITB shares today, so I was forced to cover my ITB short position by 200 shares, at $13.84.  I replenished this position by purchasing three ITB 17.50 Jul10 Put options at $3.90; these are options that I have purchased before.  Even though I am down somewhat significantly on this trade, I remain steadfast that housing is overvalued, as evidenced by my continued financial backing.
