It Turns Out That They Loved Warsh

It Turns Out That They Loved Warsh

I feel remiss that I could not comment in real time on yesterday’s stunning rally, but I was privileged to be invited to participate in the SEC’s Roundtable on Preparations for 24-Hour Trading and thus fully committed to that event.  There was indeed a stunning turnaround after the lukewarm response to Chair Warsh’s press conference, though the magnitude may have had more to do with traders’ continuing propensity to chase rallies than a sober reassessment of the fundamentals.  And this morning’s very modest profit-taking amid sharply higher yields is another sign of the “ratchet effect”.

It was interesting to piece together yesterday’s action with limited access to market data (I had my phone off through the sessions).  On Wednesday, I undoubtedly annoyed some of my fellow train passengers when I received numerous calls asking why stocks and bonds seemed to be reacting negatively to Warsh’s comments.  At one point, the S&P 500 (SPX) was off by more than 1%, which would have made it the third straight decline of that magnitude after a Warsh FOMC presser.  But we dutifully bounced off the lows, and it was more than simply dip-buyers’ catnip.  Warsh switched from talking tough about inflation to actually doing something about it, restoring a key dose of credibility to the central bank. 

Remember, traders react but investors consider.  I had dinner on Wednesday with a friend, a (happily) retired hedge fund manager who expressed a dose of relief about the FOMC’s rate action and Warsh’s messaging.  I agreed, acknowledging that 25 or 50 basis points should not be sufficient to upend a healthy economy if modest hikes help suppress inflation.  The markets seemed to concur as well, certainly by the next morning when stock futures recovered their losses and bond yields fell.  Stocks continued to rally as 10-year yields dropped, with SPX closing 1.1% higher and 10-year yields dropping by 9 basis points from 5.02% to 4.93%. 

The relationship between stocks and bonds was quite solid yesterday but has largely unraveled today.  As I type this, 2-year and 10-year yields are about 7 bp higher, with the latter once again flirting with the key (psychological) 5% level.  At the same time, SPX is down by less than 0.2% while the Nasdaq 100 (NDX) is essentially unchanged.  This is why I referred to the “ratchet effect.”  Stock traders used the positive developments as a reason to rally but didn’t seem to care when those developments turned unfriendly.  Indeed, today we see NYSE decliners outpacing advancers by about 2.5:1 and SPX net decliners leading by about 250.  The selling is a bit more broad-based than it looks.

Two breaking news items have hit markets while I was typing this.  First, we had a big rally in cryptocurrencies on reports that the CFTC will be writing a set of new crypto regulations.  That caused bitcoin to recoup the $80,000 level that it lost when the legislative efforts failed earlier this week.  Second, the yen was in the midst of a steep decline this morning, despite a 25 bp hike from the Bank of Japan.  Most of those losses reversed when the BOJ was said to be doing a “rate check”, a move that can precede an intervention.

Bottom line: the bullish sentiment remains ingrained in the equity markets, even if other key influences are quite a bit more tenuous.

Futures are not suitable for all investors. The amount you may lose may be greater than your initial investment. Before trading futures, please read the CFTC Risk Disclosure. A copy and additional information are available at ibkr.com.

Disclosure: Bitcoin (BTC) Trading

Trading Bitcoin involves significant risk. Bitcoin prices can be highly volatile and may fluctuate rapidly, potentially resulting in substantial losses. Because Bitcoin operates on a decentralized blockchain, network congestion or technical issues may occasionally delay transaction settlement. Regulatory frameworks for digital assets are still evolving and could impact availability, liquidity, or pricing. When trading through Interactive Brokers, execution and custody are facilitated by regulated partners such as Paxos or Zero Hash; however, these arrangements do not eliminate the possibility of operational or counterparty risk.

Disclosure: Digital Assets

Trading in digital assets, including cryptocurrencies, is especially risky and is only for individuals with a high risk tolerance and the financial ability to sustain losses. Eligibility to trade in digital asset products may vary based on jurisdiction.

Disclosure: Forex

There is a substantial risk of loss in foreign exchange trading. The settlement date of foreign exchange trades can vary due to time zone differences and bank holidays. When trading across foreign exchange markets, this may necessitate borrowing funds to settle foreign exchange trades. The interest rate on borrowed funds must be considered when computing the cost of trades across multiple markets.
