One look at the markets today, with the S&P making a new all time high and Europe enjoying a 10 consecutive day stretch of records - the longest since 1999, and it is abundantly clear that complacency reigns and nobody has a concern in the world. After all, why worry - the Fed will never again allow even a 5% drop in "markets."
But not everyone is convinced that they should put their entire retirement account in deep out of the money S&P call options. One is Goldman, which last weekend warned that "the ante will be upped when taper begins", leading to an adverse market outcome. Another is Bank of America whose chief equity strategist Savita Subramanian today published a note warning that the duration risk heading into Jackson Hole, where the taper announcement is likely to be made, is at an all time high.
So while there is good news - with forward S&P 500 EPS tracking +27% YTD , and the 10-yr yield dropping 40bps since March’s peak, pushing the ratio of S&P dividend yield vs. the 10-yr yield back up to 0.95x, its highest level since February and back in-line with the post-GFC average - risks loom ahead: for one, earnings growth is sharply moderating in 2H amid inflation and a slowing economy, plus "record equity duration pointing to painful downside if rates move even modestly higher." In fact, as Subramanian admits, "the market today is statistically expensive on almost every measure of the 20 metrics we track, except on growth and relative to bonds."
So back to the Taper: how does BofA quantify the risk from the upcoming Fed slowdown in TSY and RMBS purchases?
As Subramanian notes, more Fed officials are urging tapering, and implied volatility picked up after Friday’s strong jobs report as investors await commentary from the Jackson Hole conference (Aug. 26-28) and FOMC meeting (Sept. 22).
In this context, the bank's Fair Value stress test suggests that every 1bp change in real risk-free rate or ERP would translate to a 20-30bp move in the S&P 500.
So unlike other banks who have rushed to hike their S&P forecasts as the market has ground higher, BofA remains a lone bear, and its house view of 1.9% on the 10-yr yield by year-end (up +55bps from today) would translate into a ~15% price drop in the S&P 500. While that may not sound huge, considering the amount of margin leverage and negative gamma in the system, a 15% drop would likely certainly feel like a major crash to most margined market participants.
