How news affects markets

Tyler Cowen linked to a new NBER study by Scott R. Baker, Nicholas Bloom, Steven J. Davis, and Marco C. Sammon, which looks at the response of asset prices to various types of news. Here I’ll discuss the paper’s abstract:

We examine next-day newspaper accounts of large daily jumps in 16 national stock markets to assess their proximate cause, clarity as to cause, and the geographic source of the market-moving news. Our sample of 6,200 market jumps yields several findings. First, policy news – mainly associated with monetary policy and government spending – triggers a greater share of upward than downward jumps in all countries.

I’m not surprised that monetary policy is important, or that the effects are asymmetric. While one can find occasional examples of markets falling sharply on monetary policy announcements, as in December 2007, major changes are usually in the upward direction. This is because bad monetary policy generally involves errors of omission—the central bank fails to adjust its policy rate when the natural rate of interest is falling (as in mid-2008.) When the central bank does make a major move, it generally helps the situation. The problem, of course, is that central banks are too passive; too unwilling to move when economic conditions change.

Second, the policy share of upward jumps is inversely related to stock market performance in the preceding three months. This pattern strengthens in the postwar period.

Beneficial policy adjustments are less likely to occur if the economy (and the markets) has previously been doing well.

Third, market volatility is much lower after jumps triggered by monetary policy news than after other jumps, unconditionally and conditional on past volatility and other controls. Fourth, greater clarity as to jump reason also foreshadows lower volatility.

A monetary policy announcement often helps to clarify the situation. Other shocks, such as the failure of Lehman Brothers, make the situation even more confusing.

Clarity in this sense has trended upwards over the past century.

When I studied monetary policy in the 1930s monetary policy, I noticed that the policy environment was far more unstable than today, and also that the stock market was far more volatile than today. The average daily move in the DJIA was around 2%.

Finally, and excluding U.S. jumps, leading newspapers attribute one-third of jumps in their own national stock markets to developments that originate in or relate to the United States. The U.S. role in this regard dwarfs that of Europe and China.

This fits in with David Beckworth’s claim that the Fed is a monetary superpower due to the dollar’s role in the global economy. (Eurozone GDP is similar in size to the US GDP, but the ECB is far less influential.)

PS. There are schools of thought on both the left and the right that claim monetary policy doesn’t matter, that it’s just swapping base money for T-bills. They have no explanation for these empirical facts, and presumably either deny them or ignore them.

    Why does an increase in stock prices mean that the situation has improved? It seems to me to be just as likely that central banks tend to reduce interest rates, leading to higher present values of future cash flows. It’s not obvious to me that this is good (or bad) without more context.

    The problem I have with this and other papers of the ilk is that it is pretty much useless for portfolio management. Perhaps high frequency traders build some of this into their algorithms but I tend to ignore all of this as just chatter. I would like to some of these folks run a real-life portfolio with their own money on the line.

    PG, It doesn’t guarantee the situation has improved, but that’s generally the case. Monetary stimulus doesn’t always reduce long term rates. But stocks often rise even if long term rates don’t fall.

    Alan, I fail to see how that’s a “problem”, given that these papers are not trying to predict asset prices.

    The drop in interest rates during the 4th qtr. of 2008 had nothing to do with monetary flows, AD, volume times transactions’ velocity. In fact, the establishment of the IOeR remuneration rate, 2008-10-09 0.75, 2008-10-23 1.15, 2008-10-29 0.65, 2008-11-06 1.00, 2008-12-16 0.25, destroyed velocity.

    Economists are in fact, running the economic engine, the savings->investment process, in reverse. Banks are “black holes”. It is an allusion that banks loan out existing deposits.

    As Dr. Philip George states: “The velocity of money is a function of interest rates.”

    So, AD is being funded by money products, not savings’ products. So, we need an infrastructure stimulus just to keep things moving.
    Otherwise short-term money flows, volume times transactions’ velocity (proxy for real output), peaks in May and long-term money flows (proxy for inflation), peak next January.

    I can’t think of a major media outlet besides the Economist that has even mentioned AIT in the past year. Granted, I don’t watch TV and my memory isn’t trustworthy, but I feel like the “market” has responded to the Powell Fed by maintaining a certain degree of mostly upward trending stability (a permanently high plateau?).

    Most current news stories are about asset price volatility–Gamestop,etc.. or that 2×4’s cost 3 times what they cost last year. The Fed seems to be more aware of its power, and generally indifferent to market froth. There will be media hysteria through this year about specific price points for some types of labor and commodities but I hope that the governors ignore that.

    The announcement of QE2 ($600 billion of Treasury bills, bonds, and notes), was one of the most powerful examples of the FED’s communication’s impact (the failure of QE1 to stimulate the economy).

    The economy continued to falter (the nsa CPI fell in Nov and Dec), yet stocks surged higher (the Nasdaq 100 rose from 1818.8 on 8/13 to 2225.72 on 12/30) due to a rise in inflation expectations. 10yr breakevens rose from 1.49 on 8/24/2010 to 2.64 on 4/8/2010

    I’ll make a heavily qualified defense of Cochrane’s position—after all, this is the Bad Blog.

    Cochrane wants everyone to stay on their toes and raise a ruckus if CPI, unemployment rate, bond spreads, and wages are all pointing towards significant* inflation. My guess, and I’m happy for a Sumner Smackdown, is that the Fed won’t move even if we have 3 quarters of inflation that look like this: 2.2, 2.4, 2.7
    But, after the quarter with 2.7 Powell will start talking about tightening–and they’ll vote for a 25 basis point move.

    And if we have 3 quarters of 1.9, 2.0, 1.9 we should expect no action, no matter what’s happening in all the FRED charts.

    *And what is significant? A few years of inflation that matches 1988 to 1991 maybe? Or 98 to 2000?

    Given that money is nearly neutral, a better way to interpret this study, which confuses causation and correlation, is to say the Fed during boom times makes policy decisions that affect day traders (more than half of the time the stock market is trending up anyway). That’s all. How long does the Fed effect last? A few hours. That’s how long money is not neutral. Sumner is impressed by this? He’s probably impressed by PR releases that cause a temporary jump in stock prices too.

    Monetary policy is a scam.

    The banks borrow from American tax payers at zero percent to cover their 10% obligations, which reduces their risk to essentially zero. If the loans fail, and threats to sue are ignored, they simply write it off and borrow more. Only the idiots actually file bankruptcy. Smart money knows that if you ignore them they won’t do anything, unless you owe them millions. Why would they, when they can simply go back to the well.

    And low and behold, access to this ponzi club is exclusive. You and I cannot create a bank and borrow from the American tax payer at zero percent.

    The only thing holding up the U.S. economy is the reserve currency factor. Without that, the currency would be nearly worthless.

    It is interesting how few economists study the relationship between the economy and the stock market. There are some who claim that there is little if any relationship, when the reality is quite the opposite. The vast majority of changes in stock prices are due to changes in economic growth expectations.

    Also, it has surprised people so far, and even surprised me, how high the correlation is between 1 year Treasury yields and the S&P 500 earnings yield. It is 0.745, which is the second highest correlation I’ve seen in macroeconomic data. Of course, the 1 year Treasury rate tracks the Fed Funds rate extremely closely.

    The only macro correlation I’ve seen that’s higher is that between the Fed Funds rate, and core PCE inflation, which is about 0.80.

    re: “The vast majority of changes in stock prices are due to changes in economic growth expectations”

    Economists are arrogant. They’ve learned their catechisms.

    Take the NYT: “News of the tax provisions appeared to unnerve investors on Thursday, with stock markets giving up gains as investors absorbed details of Mr. Biden’s capital gains tax plans. The S&P 500 closed down 0.92 percent.”

    That was just a news trigger. The rates of change in the economy and inflation have already peaked and are headed lower.

    @Michael Sandifer: It’s interesting to note that 1yr Treasury yields represents the “money market” yield, The money market is differentiated by its position on the yield curve (i.e., short-term borrowing & lending with original maturities from one year or less).

    As George Selgin told us: Paying interest on reserves is illegal at these rates of remuneration (rates higher on the front-end segment of the money market retail and wholesale funding yield curve, or the FRB-NY trading desk’s synthetically inverted yield curve, viz, a credit control device anchored on the front-end). This Romulan Cloaking Device exceeds the level of short-term interest rates which was explicitly illegal per the FSRRA of 2006.

    @Ray Lopez re: “A few hours. That’s how long money is not neutral.”

    You’ll say anything to get attention. The neutrality of money is a function of the distributed lag effect of monetary flows, volume times transactions’ velocity. It is demonstrably a function of (the gap between) short-term money flows (proxy for real output), vs. long-term money flows (proxy for inflation).

    Note: “Neutrality of money is the idea that a change in the stock of money affects only nominal variables in the economy such as prices, wages, and exchange rates, with no effect on real variables, like employment, real GDP, and real consumption.” Wikipedia

    @Michael Sandifer says “The vast majority of changes in stock prices are due to changes in economic growth expectations” – Wrong. (internet): Dimson, Marsh and Staunton (DMS) studied the relationship between long-term stock market returns and long-term GDP growth.1 Their sample included a cross-section of 21 countries with equity return and GDP growth data from 1900 to 2013. Fifteen of the 21 countries were in Europe, so the sample largely represented a similar economic history. The DMS researchers found a modest negative correlation between real (inflation-adjusted) equity returns and per capita GDP growth, and they found a modest positive correlation between real equity returns and aggregate GDP growth. The results were mixed and the evidence linking equity returns to GDP growth was weak, surprising many investors and economists.

    @Spencer Bradley Hall – wrong. The QTOM is an accounting identity. Since velocity is not constant, it explains nothing. Try harder next time.

    @SS–you’re in form, as obscure as always. And misunderstood.

    @Michael Sandifer – an amplification to my previous post. If you’re saying that PE expansion can occur due to investors anticipating higher growth, and this pushes up stock prices, then you’re kind of right, but PE expansion can occur from any ‘enthusiasm’ by investors. They can anticipate higher growth or simply anticipate more people will like stocks. Growth is a red herring in this analysis, and explains nothing.

    Does this reveal an EMH problem? You know that the Fed tends to act too slowly. Presumably others know that too and that knowledge will be reflected in prices. In other words, since the Fed’s tardiness is predictable, why wouldn’t its tardy action already be reflected in prices?

    Powell doesn’t know money from mud pie.

    ““This change means that savings deposits have had a similar regulatory definition and the same liquidity characteristics as the “TRANSACTION ACCOUNTS” reported as “Other checkable deposits” on the H.6 statistical release since the change to Regulation D.”

    But the turnover ratio of the sub-component: “total checkable deposits” to “other checkable deposits” is 95:1.

    No money stock figure standing alone is adequate as a guide-post for monetary policy.

    WSJ 6/28/1983: “The experimental measures are designed to resolve some of the confusion by isolating money intended for spending, from the money held as savings. The distinction is important because only money that is spent-so-called “true money” – influences prices and inflation”

    He echoed the same thing Greenspan did:

    “In July 1993, Chairman Greenspan informed Congress that the monetary aggregate, M2, had been “downgraded as a reliable indicator of financial conditions in the economy, ” reflecting the fact that “the historical relationships between money and income and between money and the price level [had] largely broken down.”
    Federal Reserve Bank of San Francisco | Is It Time to Look at M2 Again? (frbsf.org)

    Jerome Powell should be fired. He failed to solicit comments and obtain consensus in the Federal Register. “Powell: “the correlation between different aggregates [like] M2 and inflation is just very, very low”.

    Powell is vacuous. So is William Barnett of Divisia Monetary Aggregates. Divisia Inside Money Aggregates – The Center for Financial Stability

    Neither applies the distributed lag effect of monetary flows, volume times transactions’ velocity, to AD. Contrary to Nobel Prize–winning economist Milton Friedman and Anna J. Schwartz’s “ A Monetary History of the United States, 1867–1960 “ monetary lags are not “long and variable”. The distributed lag effects for both real output and inflation have been mathematical constants for over 100 years.

    Powell: “there was a time when monetary policy aggregates were important determinants of inflation and that has not been the case for a long time”

    Not so. Over longer periods, the U.S. $ indices reflect FOMC ease or tightness.

    As an example, the price of oil troughed in Jan 2016 as long-term money flows fell by 80 percent from 1/2013 to 1/2016. Oil fell by 70 percent during the same period. The Trade Weighted U.S. Dollar Index: Broad, Goods and Services rose from 1/2/13 to 1/4/16 from 90.6941 to 114.1596. Gold fell by 57 percent from 1681.50 to 1072.70. And the real rate of interest rose dramatically off 2012’s lows (from -0.87 on 12/10/2012 to 0.86 on 9/10/2013).

    The increase in non-M1 components destroys the velocity of circulation. There’s no way M2 is accurate. See Dr. Philip George’s: “The Riddle of Money Finally Solved”.

    And as Dr. Philip George says; ““When interest rates go up, flows into savings and time deposits increase” ( the ratio of M1 to the sum of 12 months savings ).

    That destroys the velocity of circulation as banks don’t loan out deposits. It is a wholly unrecognized fact. Deposits are the result of lending/investing. All bank-held savings are lost to both consumption and investment, indeed to any type of payment or expenditure.

    Stocks typically follow short-term money flows. The U.S. $ follows long-term money flows.
