It's a great quarter guys

My colleague Don shared this.   Apparently, more often than not, equity analysts will tell CEOs "it's a great quarter guys".

It is pretty common for "great quarter" stocks to tank shortly thereafter.

The fact that the analysts are so cosy with the CEOs of the companies that they cover says it all.   As I used to say to my students in my equity analysis course - you don't work for the company and you don't owe the company anything.  Your analysis must be at arms length, otherwise you risk suffering from Stockholm syndrome.

Spoofing and and herd behavior

John Cochrane (of U. Chicago) has an enlightening post about the practice of spoofing (creating fake orders to lure other traders to do stupid things).   Suffice to say, Cochrane isn't a big fan of regulation that prevents traders from being dumb.   He's probably right.

NC Pension Fund Fees Approach $500 Million

Andy Silton does the math and reports that fees for the pension fund are approaching $500 Million.

Just so we are clear here, that's $500,000,000.

So what are we getting for all these fees?   Apparently not a whole lot of extra performance - which is no surprise to anyone who believes that markets are pretty efficient (they are).

Silton points out that otherwise the fund is in good health - which is good, but that doesn't make wasting hundreds of millions of dollars a year any less bad.


The question we should ask then is "how much should these fees be?"

I'd answer that for such a huge portfolio, 0.1% of assets is a good start, as I can pay only 0.18% for $3000 with Vanguard and it seems reasonable to assume that $90 billion would get some sort of discount.

So assuming $90 billion in the fund, 0.1% fee would yield $90 million in fees.  But even if you go with the Vanguard fee of 0.18%, we're still only looking at $162 million.   That's $338 million less that what we are paying.

Do CEOs time option grants relative to stock splits?

This post is based on a paper coauthored with Erik Devos of UTEP and Bill Elliott of John Carroll University.



To answer this question, we need a quick recap of options and splits.

Stock option grants frequently make up a significant portion of CEOs' compensation packages.  Typically an option is granted to the CEO "at the money" meaning that the strike price is set close to trading price of the stock.  If the stock price increases after the option grant, the value of the option will increase.  This is a standard property of call options and is the prima facie reason for granting them in the first place.

Stock splits are, by and large, cosmetic changes to the stock.  A 2 for 1 stock split results in each share of stock being replaced with 2 shares.   In such a split, the stock price should fall in half, so a $100 stock will split to two $50 stocks.   In reality, the $100 stock splits (on average) into two $51.50 stocks.   In effect a $3 or 3% gain in value occurs on the announcement day of the split.  The key thing to note here is that this is "on average".  Why this occurs is a bit of a mystery and beyond our discussion today.

So given these two factoids - options are granted at the money and stock splits result in a price increase (split adjusted) - when would a CEO most likely want to get an option grant?  
A. Before the split announcement.
B. After the split announcement.
C. The CEO shouldn't care.


If you answered A, then you'd be right - and this is supported by the data.


This figure shows the number of grants made relative to the split announcement.  Clearly, there is clustering before the announcement on day 0.  So what's going on?

Because a grant is granted "at the money", the 3% price bump that occurs on the split announcement results in an immediate increase in value for the holder of the option.  Therefore a CEO would prefer to get his/her options before the split rather than after it. 

But the story is more tricky - as this result holds for scheduled grants (grants which occur at a pre-determined time each year).  This means that in some cases the split announcement is being timed relative to the grant.

OK but so what?

On average, by granting before the split, a CEO will see his/her wealth increase by more than $450,000!   This is based on the size of the grant and the effect that a 3% stock price increase has on the value of the option.

In case you are wondering, CEOs also appear to time their stock trades relative to split announcements.



These findings are forthcoming in the Journal of Accounting and Economics in the following paper:

“CEO Opportunism?: Option Grants and Stock Trades around Stock Splits”

Flash Boys - my review

I finally got around to reading "Flash Boys" by Michael Lewis.   Bottom line, like a lot of non-fiction books, it is pretty good, but probably could be half as long.

The basic story, in case you haven't read it is as follows {SPOILER ALERT}

  • RBC Equity trader suspects that his trades are being front run  - someone is anticipating his moves and then picking off his juicy trades by jacking the price very slightly.
  • After much research (using LinkedIn and experts in fibre optic cables) he figures out the problem.
    • The fragmented nature of equity markets - there are more than 30 equity trading venues - coupled with the speed at which information flows from one market to another - allows high frequency traders to lure trades to one market then pull back depth and pick off the trade at the next market.
    • The solution is to slow down trades
  • RBC Equity trader quits his day job and creates a new exchange which works on the idea that by slowing down trading, you remove the advantage to the HFT guys.
  • After a slow start, the new exchange does really well, because people hate getting ripped off the by the HFT guys.   
  • The exchange is still going:  http://www.iextrading.com/
There are a couple of side stories.  Apparently someone is laying fibre from New York to Chicago.   Also a coder goes to jail for apparently stealing open source code from Goldman.  But really he wasn't a bad guy.

Overall, worth a read if you are interested in HFT, but if you are not, then it's a pretty geeky book and probably not worth the effort.

The broader takeaway from the book is that a huge amount of money is being made from HFT.   Because HFT isn't a value creating enterprise, and the stock market is basically a zero-sum game, this means that this money is coming from investors.  Investors who have money in pension funds and mutual funds etc.  People like me.

Bottom line.  To quote Josh Brown: "The way to defeat high frequency traders is to be a low frequency trader"

Buffett's bet against a Hedge Fund manager

We're in year 6 of Warren Buffett's million dollar bet against Hedgie Ted Seides.   Buffett bet that the S&P 500 index would crush a portfolio of hedge funds hand picked by Seides.

So far, Buffett is correct.  The index is stomping on the hedge funds.

Of course, there's no surprise here.  If you are interested in long term capital appreciation a portfolio of indexed stocks will virtually always outperform a fund that is charging 2/20 and is run by people who think that they are smarter than the market.

What's amusing is that Seides is now coming up with excuses for why it's not a fair competition.  You can read them here

Thanks to my accounting colleague, Don for the link.
