Does High Frequency Trading add value to the market?

Reading Mark Cuban’s post about High Frequency Trading (HFT), indeed, I agree with him that it provides little value to the marketplace.

The incentives are completely geared toward having it, however – the stock exchanges make money on volume and have no incentive to stop it. The traders themselves are able to do it profitably and have no incentive to stop.

The easy solution to fix this problem is to simply transform the stock market into one second auction windows – i.e. every second that the stock market is open (6.5 hours, which translates into 23,400 seconds) bids and asks are aggregated and transactions are appropriately processed.

This would also undermine the value of sub-penny quotations and seriously reduce the value of phantom quotations that try to “probe” what hidden support there is in the order book.

There would be a decrease in volume, but most of the volume you see today is “phantom liquidity” – it is liquidity that would never be truly accessible for somebody wanting to accumulate or distribute shares at a certain price level.

This change is unlikely to be enacted, however, since it does nothing politically for those that control the securities commissions – the regulators’ incentive structure is favoured toward higher complexity, and thus more requirements for regulation.

More specifically, securities regulations has little to do with “investor protection” – rather, it is about entrenchment of established interests.

Generating synethic performance – catering to yield chasers

Finance is a very funny industry. The primary way of keeping score, change in cash, is not really used as a performance measure. Instead, the performance measure is return on investment, which is a proxy for change in cash, but not the same. Return on investment is a flawed metric because it does not take into account risk.

A clever formula to weighing historical risk and performance is the Sharpe Ratio, but I will leave that mathematical dissection (and the weakness of the Sharpe Ratio) for another post.

If I told you that I made 2% this year, an observer in an “up” market environment would say that is a horrible return on investment and bad performance. If I then said that my portfolio was 100% cash, then the performance would be fantastic. You might chide the decision to be all-cash in an up market environment (missing the wave) but at least the performance in the constraints of a 100% cash portfolio was great (given that the most you can do these days is less).

However, if you wanted to juice your performance, the drug of choice in the finance industry is leverage. And in today’s interest rate environment, the rate on leverage is cheap. Even retail investors can get into the action by loaning money from Interactive Brokers (depending on how much money you actually borrow – the first US$100,000 is at 1.65%, the next US$900,000 is at 1.15% and the next US$2,000,000 is at 0.65% and everything above that is at 0.5%).

Assume you get a 1% borrowing rate, which makes the arithmetic easy. So if you manage to earn a 2% average on cash, why not borrow cash at 1% to invest it at 2%? So I will set up a mutual fund. All I will do is invest at a risk-free rate of 2%, and apply some leverage. I invest $100 in my own fund, but borrow $900 at 1%. What happens financially?

Interest income: $20
Interest expense: $9
Net income: $11
Return on investment: ($11 net income / $100 equity investment) = 11%!

So I have magically transformed what was a 2% return into a 11% return with the magic of leverage. Using this technique, and unlimited borrowing power, I can generate any return on investment you desire. Want 101%? Easy – borrow $10,000 instead.

This concept is introduced in introductory level finance courses across the world, but most people fail to appreciate how the rate of return figure that is being advertised in a lot of cases is simply a synthetic return. The use of leverage creates this return. Parenthetically, a similar way of generating “synthetic yield” was used in the mid-2000’s when income trusts were raising equity capital and just giving back cash to unitholders as a return of capital to generate false yield when they weren’t really making any money to justify their distributions.

Where do you see synthetic performance currently occurring? Mostly in the US financial REIT markets like Annaly (NYSE: NLY) and others. They borrow money for cheap, invest them in mortgage-backed securities, and then skim the spread. They goose their performance with leverage.

While this is a valid way of making money, the danger is on the reliability of returns – even if the asset you are investing in inevitably gives out the desired return (both of interest and principal), if the asset value itself has severe variations, funds will be forced to liquidate such securities for losses because they will have lost borrowing power. If you have enough capital being driven into these financial structures and they keep leveraging the capital to generate high returns, there will be some blowups along the way simply because the asset pool they are investing in will be well above true vale. One blowup will likely cause others to blowup since they are essentially invested in correlated products.

Yield-chasers are going to get crushed. I am not sure when this will occur, but the current trend toward yield chasing is crystal clear. I’m not going to be shorting such securities presently since I think the momentum still has quite some way to go, but when this insatiable risk reaches some sort of crescendo, that would probably be a good time to sell everything and wait for a 2008-style crash in asset values. Maybe in 2013 or 2014?

Sometimes, doing nothing is best

Letting your winners run is an art. When you do this, capital compounds on capital – if you bought something and it goes up 10%, suddenly you have 110% of your original investment in play, and a 10% gain on top of that will not result in a 120% investment, but rather at 121% of the original investment. In a more extreme case, when something you own doubles, it only requires a 50% gain from that point to amount to another double on the original investment.

This must be balanced off with knowing when to take gains. That time is not now. Everything in my portfolio at present I have a reasonable price target of above the current market value. If anything, I should be adding to the positions.

So the best action I can take is to twiddle my thumbs. People feel fearful of the equity market at present, which is good.

Summer doldrums

I have not been doing much equity research over the last little bit as recreational matters have generally dominated the landscape. One chart I have been curiously watching, however, is the 10-year note yields, which has dipped from its 1.4% minimum:

Which way are the yield winds blowing, up or down?

The Canadian 10-year note equivalents have a similar yield curve and are trading about 15-20 bps above US treasuries in yield. One would think that you could do better than 1.8% over 10 years by taking a little bit of risk…

Filtering Yahoo Finance News

Over the past couple years, the news portion of the Yahoo Finance portal has been increasingly filling with useless computer-generated articles, such as Forbes articles on every stock that is going ex-div, or paying out their dividend:

Is there any way to filter this type of stuff (or anything from Forbes, the Motley Fool and Seeking Alpha)? I’m finding going through my email spam box to be a slightly more productive use of time than sifting through these types of “news” headlines.
