John Hussman tonight is particularly nervous about the stock market’s near-term prospects, and he has this to report after reading Fannie Mae’s 10Q:

With regard to Fannie Mae’s report, the most interesting figure wasn’t the reported $2.3 billion loss, but rather the much larger deterioration in the reported fair value of Fannie’s balance sheet. We can observe what’s going on by comparing Table 32 of Fannie Mae’s Q2 2008 10Q filing with the same table in Fannie Mae’s Q1 2008 10Q filing.

As of June 30, 2008, the fair value of Fannie Mae’s common equity (that is, the book value available to common shareholders) was -$5.39 billion, compared with a March 31 fair value of -$2.07 billion. What’s notable here is that this deterioration (-$3.32 billion) was even larger than the -$2.30 billion loss that Fannie reported to investors, which was itself about four times higher than the loss analysts had estimated. Note that balance sheet losses are excluded from earnings. Financial stocks tend to be reasonably valued when they trade at tangible book value, but simply put, Fannie Mae has no tangible book value. The common stock is now a call option.

Even if we include the fair value of preferred equity, we find that on a fair value basis, Fannie Mae is operating at a gross leverage multiple of 72.7 (total assets comprised primarily of mortgage loans, divided by shareholder equity). In other words, a slight 1.4% deterioration in the value of Fannie’s book of assets will wipe out all of the remaining shareholder equity. This makes Long Term Capital Management look like a conservative strategy.
