Example 16.5 (Right, and unprofitable)
A thesis worth a 25% fall has days at a fee of 40% and 112 days at 80%. Figure 16.3 follows a short of 100 000 shares at $40 over a simulated year in which utilisation climbs from 60% to 99%. The stock first rises to $53.52 on day 94, a loss of $1.36 million. On day 190 it is at $31.20 and the position is $789 000 ahead. By day 250 the stock has recovered to $38.36, still below the entry, and the borrow has cost $399 000, three quarters of it in the last sixty days: the trade has lost $235 000.
