Algorithmic Trading - Why Indian Stock Markets are Endangered


A few months ago, I had blogged about tight coupling in financial markets. In that entry,I had explained at a micro-level the impact of algorithmic trading. Given below is a "macro" story about how high-frequency trading in securities using computer programs played a big role in (though I would stop short of saying that they caused) a violent fluctuation in shares' and securities' prices on Wall Street last year. In less than 15 minutes, the Dow Jones Industrial Average Index plummetted and lost almost 6% of the opening value - and then recovered almost all of it in the next 15 minutes.

What happened on May 6, 2010 on Wall Street?


Major equity indices in futures as well as securities markets, already down 4% from the earlier day's close, suddenly plummetted a further 5-6% before recovering equally quickly, all in minutes. This affected almost all the 8,000 securities and ETFs in similar manner. Over 20,000 trades were reported to have been transacted at prices 60% from their prices just a few moments earlier.

Why did this happen?

At 2:32 pm, on an already volatile day, Waddell and Reed Financial Inc (not named by the joint CTFC-SEC report dated Sept 30, 2010, but named by many news reports) started a computer program to sell 75,000 E-Mini futures contracts worth close to $4.1 Bn. This was programmed to sell at any price and time, so instead of an orderly sale over a few hours, it sold this huge quantity of contracts within the space of 20 minutes, accelerating the sales as prices fell.

What actually happened during the crash?

The contagion spread to the equities market when arbitrageurs noticed the growing gap between the equities and futures prices. A significant finding is that 6 HFT (High Frequency Trading) firms (i.e., firms that extensively used algorithmic trading) remained active in the market even during the crash period of a few minutes. A blow-by-blow account follows:
  • Five minutes into the crash, at 2:37 pm, data feeds from computers groaning under the huge numbers of contracts, started slowing down, leaving both, exchanges and investors uncertain about where share prices stood.
  • The NASDAQ went into “self-help mode” at 2:37 pm where the transactions were not routed through NYSE's Arca electronic trading platform. CBoT and BATS exchanges (BATS at 2:49 pm) followed and also went into “self-help mode” which means that trades on NASDAQ, CBoT and BATS did not need to honour an Arca quote from NYSE.
  • By 2:40, some trading and market-making firms started pulling out, due to algorithms that pause when they sense large price movements that could be due to questionable data feed. This left the market short of ready buyers and sellers. Apple, for example fell by $23 in 2 minutes, with the buy-sell spread going up to $5 instead of a few cents.
  • Volumes of E-Mini contracts that normally mimic the S&P 500 surged but liquidity dried up. As a result, at 2:45:17 pm, E-Mini prices plunged 12.75 cents in half a second. This set off a circuit breaker that halted trading for 5 seconds.
  • As individual stocks declined as much as 10%, ETF traders started withdrawing from the market.
  • Then, at 2:46, even more strange things started happening because of the sheer speed difference between trades being put through and displayed – P&G shares were offered for purchase at prices higher than offered for sale! This is never supposed to happen in an electronic exchange.
  • At 2:47, Dow reaches its nadir for the day, down 998 points or 9.2% from the opening level. Accenture, trading minutes earlier at $40, was offered at 1 cent.
  • Then, at 2:49, the Dow rebounded by 300 points in 1 minute.
  • There were no takers for ETF shares – iShares S&P500 Value Index Fund traded for 11 cents. But the broad recovery continued. By 2:58, indices reached the level they were at 2:30 pm.
  • At 3:01, almost a half-hour to the minute since the crisis began, NASDAQ snapped out of its self-help mode and resumed routing orders to the Arca trading platform.
  • At 4 pm, the DJIA closed 340 points below its previous close.

The Joint CFTC-SEC investigating committee reported that several HFT firms they interviewed had algorithms that took trading decisions based on direct proprietary data feed from the exchange directly rather than on consolidated market data, to reduce “latency” or delays measured in milliseconds. These algorithms went awry when the data feed from the exchange slowed down. Those HFT firms that did not depend on direct feeds for trading decisions got contradictory feeds that led to unease in taking decisions. Yet others that were not concerned with data latency in milliseconds simply withdrew from the markets.

The HFT firms that depended on their algorithms for trading decisions were not affected by the “self-help” declarations of NASDAQ, CBoT and BATS, and continued to rout orders to these exchanges. Therefore, the “self-help” declarations were ruled out as a cause of the volatility.

While no clear single cause was pointed out, HFTs using algorithms to trade rapidly (in one documented case, 200 trades exchanged hands 27,000 times in 14 seconds) were commonly thought of as the villains. It must be said, though, that there have been spirited defences by algorithmic trading experts, who point (among other factors) to volatility when markets are closed (ie difference between closing prices and opening prices on next day) as the real villain of the piece – on the logic that overnight differences can only be caused by humans, who are prone to panic unlike computers.

Even so, the SEC has since instituted a system of circuit breakers to arrest rollercoaster falls like the one experienced on Wall Street on May 6, 2010. This is another lesson that they have learnt by experience – instead of simply looking eastwards and learning from Indian bourses.

What can we learn from this?

But now, the stage has come to re-learn from our own wisdom. Algorithmic trading is now allowed on Indian bourses. Reports have suggested that over 40% of all trades are done by computers on NSE and BSE. Add to it the other dangerous fact - that FIIs that invest "hot money" that can fly out of the country in seconds account for over 70% of all floating stock (ie, stock that gets traded on the bourses).  See this in juxtaposition with the often displayed behaviour of FII fund managers who, like a herd of sheep, make a beeline for the two exits (NSE and BSE) for their investments at the merest sniff of danger anywhere in the world (even if it does not endanger their holdings in India), and it becomes clear that we have set up our bourses for spectacular volatility where securities' prices falling off a cliff in minutes will become sickeningly regular occurrences.

Putting the Bank of America situation in perspective

What would you think of the state of the Indian economy, if what I said of BofA and Citibank was said of State Bank of India and ICICI Bank in India by some economist of repute? 
The situation is that serious for the US and for many countries in Europe, where the nation's top banks have dug themselves into deep holes that not even the EU or their respective Governments can afford. All these economies have their underbellies exposed.
On both continents, banks are hiding behind accounting gobbledygook called Impairment and Fair Value Accounting. But the understanding is filtering through. Tonight (in India) brought news of a blood bath on bourses in the US and Europe. So tomorrow (19th August) will almost certainly see a bloodbath on Indian stock exchanges - as FII Fund Managers make a beeline to the nearest exit. Expect a fall of at least 400 points in the Sensex on 19th August, 2011 before short covering enables a partial recovery.
I believe that this is the beginning of the unravelling of several economies in Europe and of the US economy as well, with them slipping into R-2, needing QE-3 and possibly QE-4.
I shall write again tomorrow to report whether what I said about the bloodbath on Indian stock markets was accurate. I feel comfortable making these gloomy predictions because I currently am sitting on cash, having (fortunately) believed in my own predictions and taken my own advice!

BofA: The vultures are gathering ...

Barely 3 days after I blogged on the death spiral Bank of America seems to be sliding into, the signs of death throes have become clearer. Already, its share price represents only 32% of its book value, showing that the market agrees with my assessment that its assets are massively overstated. I had pointed out only one asset, Goodwill, that called for significant impairment.  
Wall Street Journal now reports that Bank of America has entered into deals to sell the following:
  • its Canadian Credit Card portfolio to TD Bank
  • its Spanish Credit Card unit 
  • its small-business cards in the UK to Barclays
WSJ also reports that BofA intends to sell other card units in Europe. It further speculates that BofA may also sell its stake in China Construction Bank Corp. Another report states that Bank of America has also sold off portions of its credit card business within the United States to Sovereign Bank and to Regions Financial Corporation. In April this year, BofA sold its stake in Black Rock Inc.. 
All these sales are obviously intended to shrink its way into a viable situation by raising money without a share issue, and also thus raising "tangible net worth per share" of Bank of America.
If you think BofA was the only bank in trouble, look at this list of 64 FDIC-insured banks that have failed and closed down in the first 7 months of 2011. This is in addition to 157 banks that failed in 2010, and 138 in 2009. It is obvious that things aren't getting better. But that they have company is cold comfort for BofA, around whom vultures are gathering. 

  • In early 2011, it settled charges of mortgage-backed securities fraud charges with BlackRock, PIMCO, Freddie Mac, Fannie Mae, insurer Assured Guaranty and a few others, agreeing to pay $8.5 Bn. These settlements have run into some trouble, and are now facing opposition.
  • Already, AIG has claimed $10 Bn damages for securities fraud in sale of mortgage-backed securities by BofA, Merrill and Countrywide. 
  • In addition, over 90 similar suits have been filed demanding damages of $197Bn, says the above article, quoting LawyerLinks, a legal consulting firm.
  • Now, it  is being reported that the National Credit Union Administration has declared that it is suing several banks for damages of up to $50Bn for misrepresenting safety of securities it sold to several credit unions that collapsed as a result of the investments. Among those likely to be sued is Merrill, now part of BofA. 
  • Credit Default Swaps on BofA have risen to their highest level since May 2009, showing nervousness of investors.
  • BofA has begun writing down principal on Californian "underwater" home loan mortgages of troubled borrowers. BofA is reported to be seeking immunity from prosecution in return for paying fines and writing down principal outstandings of underwater mortgages.
  • Elsewhere, BofA is facing energetic protests from locals fed up of the number of foreclosed properties that are ill-maintained, sending property values in entire localities tumbling. 
  • The richest Hedge Fund Manager in the world according to Forbes' 2011 List of Billionaires, John Paulson, and who is known for sticking to his bets for longer than most fund managers, has sold half his stake in BofA and Citigroup.

There is speculation that it could spin off Merrill Lynch Wealth Management and Investment Banking operations. There is also some speculation that BofA could put Countrywide, acquisition of which is by consensus considered as a big corporate blunder, into bankruptcy. However, moves taken to consolidate Countrywide and BofA have clouded BofA's ability to ringfence Countrywide-related liabilities. 
Watch this space!

The Death Spiral beckons ...



Bloomberg reported that as of August 10, 2011, 186 US-based financial services companies traded for less than 60 percent of their book value, or common shareholder equity, including Bank of America, Citigroup Inc., Morgan Stanley, AIG and SunTrust Banks Inc. Together, they had a market capitalization of $300.5 billion, compared with $686.4 billion of book value. This means that a fall in their share prices to this extent (40%) is well nigh inevitable. 
How likely? These banks are very, very vulnerable. For example, earlier this week, AIG filed a suit accusing Bank of America of securities fraud; demanding damages of $10Bn. This sent the BofA stock down 20%, in addition to the bloodbath that the Dow Jones has experienced in the week after August 2, and the S&P downgrade. Its market cap stood reduced to $68.6Bn. Compare this with just one year-end intangible item on its 2010 Balance Sheet: Goodwill is shown at $73.8Bn (see p.130, Table XIII. See also Footnote 1 below)  – forget the rest of its balance sheet, BofA would have the world believe that this intangible item alone, built up from excess over book value paid for its past acquisitions, is worth more than the entire BofA is worth on Wall Street. How many will believe this, and for how long? There will always be the small boy who shouts, “The Emperor is not wearing any clothes!”. After reading Page 114-115 of its 2010 Annual Report, any accountant will understand that BofA will have to write down goodwill significantly (it wrote down $12.4Bn in 2010) - and to keep the shareholders' equity intact after this write-down, it would need to raise more equity. The dilution this would almost certainly drag the share price lower. Which will require them to raise more equity at even lower prices ... leading to a death spiral.
What about the demand for financial sector shares? All but non-existent. Retail interest was never very visible in the US in equities; now it has disappeared. Institutional investors are worried about what write-down of such intangibles would do to the Balance Sheet – and will stay away from any further issues in sufficient number as to make a public issue a very big gamble that could very easily fail. So the only solution – a government bailout wherein the financial institutions that still bear the TBTF tag (Too Big To Fail) are partly nationalized. Expect this to happen in the not too distant future, when the pressure of reporting numbers that have no relation to stock market prices forces them to look for ways of raising their net worth to blunt the edge of the writedowns that are inevitable already. 
What if the US Government finds it politically unpalatable or impossible to rescue these firms with a QE3? Refer to the title of this post! 




Footnote 1 referred to above
Table XIII on p.130, and Table XII and Table XIV before and after it, were the result of BofA's attempt to dress up their Income Statement and Balance Sheet, and the justifications for using these were on page 40. If they had followed GAAP alone, the Tables and the explanation on p.40 would be unnecessary. They used "non-GAAP measures" - euphemism for accounting legerdemain to make accounts smell sweeter, euphemism for which is "additional clarity". The footnote to Table XIII reads: Presents reconciliations of non-GAAP measures to GAAP financial measures. We believe the use of these non-GAAP measures provides additional clarity in assessing the results of the Corporation. Other companies may define or calculate non-GAAP measures differently.

Not a good time for any stock market

.
Airline and automobile industry have always been GDP multipliers. That is because of the huge direct and indirect employment they generate, both upstream (component and ancillaries manufacture, assembly, services) and downstream (sales, service/ maintenance, spares, travel and tourism) besides the airline manufacturers and operators themselves. When any of these industries get hit, the economy gets multiple hits.

Of the two, the airline industry is more vulnerable to random hits, because of the global nature of their operations. Not only are they buffeted by almost every risk there is, including terrorism, hijacking, fuel price and availability risk, currency fluctuation/market volatility risks, political and taxation-related risks, etc., but they are also vulnerable to Mother Nature – sudden “clear air turbulence”, volcanic ash, storms, lightning and bird strikes, storms, besides risks arising out of mechanical, electrical, hydraulic and electronic failures, Air Traffic Controllers' errors, pilot error, irate governments who impound planes to score political points, militant cabin crew and pilot unions, irate customers demanding refunds and free accommodation, careless loaders, .... the list is endless. There is no other industry I can think of, that has such a profusion of risks to contend with every single day. Of course, the insurance industry is a close second.

The automobile industry is already doing very badly in all countries save China and India, thanks to the 2008-9 meltdown and recession, and these two markets are becoming hyper-competitive, thinning the margins and making the business environment even more difficult for all players.

When both these industries are doing badly, it is well nigh impossible for any economy to grow, especially in developed countries where markets are already very developed, saturated and competitive. Add to this fiscal profligacy of successive governments and you have a great recipe for financial disaster. This is what Europe and the Euro area is facing today.

With growth rates of all these economies being in the low single digits where positive, and negative in most places, it does not take much to knock an economy, and by extension, due to globalization, an entire region, off-balance. The recent volcanic ash episodes have paralyzed much of Europe, especially the UK for upto a week. Given that a week is almost 2% of a year, loss of such a level of business more than once in a year is a luxury that any European country can ill-afford. We are already into the second bout of airport and airspace closures, and Katla, the bigger next-door volcano, has yet to erupt! Add to it the cost and turmoil of elections (in the UK), fiscal profligacy (Greece, Spain and Portugal) and strikes and unrest (Greece) and it would be a very credulous person who would bet on the European economy growing over the next two years.

Because of the very interconnected nature of markets, it takes seconds, not years, for any contagion, whether of optimism or pessimism, to travel across the globe. So brace yourself for stock market failures. This contagion will definitely travel to India, for no mistake of it own, except Indian markets' connectedness with world markets and contagiousness of investor sentiment.

More on the Iceland Volcano

.
This updates my blog entry on Saturday, 17 April.

From the initial announcement of airport closures for 2 days, now the closure has been extended to 21 April -- a full 7 days after the volcano erupted for the second time since March. The real point no one dare ask aloud is, how do they know? The last time the volcano erupted, it continuously erupted for 14 months.  Besides, the neighbouring Katla volcano, being bigger, remains a big threat. It has erupted shortly after the current volcano in both its earlier eruptions in the past 1100 years. The odds are, that it could explode too. Understandably, nobody wants to talk much about this possibility, because the impact is too mind-boggling to consider seriously.

Now, after 5 days of ash spewing, the New York Times is tentatively speculating about how the economic fallout could hurt Greece really bad if the disruption extends into the holiday season, which could affect tourism there. A full three days after I said something similar on my blog, and four days after I actually acted on by apprehensions.

Now people have begun talking about other secondary effects -- on airline profitability, on overnight parcel delivery firms, on floriculture and horticulture product exporters to Europe, on overall productivity because people cannot get to work, and on overall health because of possible rise in respiratory illnesses. People profiting are rail, road, taxi businesses, and the hotel and hospitality industry. However, this is still being seen as a regional issue (Euro region) but it will not be long before analysts and journalists start considering it a global issue, not just because of the global warming potential with so much more CO2 in the atmosphere, but also because of the secondary and tertiary economic fallout that can be felt all over the globe, and in unlikely places. Like the fallout of 9/11 on someone living peacefully in Kirkuk in Northern Iraq.

In one of my earlier posts, I had said that I am an incorrigible optimist, but talking like this could make me sound like a perennial pessimist. This is a risk I am glad to run, for taking a long hard look at what could happen, and taking the only fail-safe option open today to a small investor with limited risk appetite.

The Icelandic Volcano and its possible fallout

.
The unpronounceable and unspellable volcano in Iceland has been spewing ash for 3 days, from 5 different plumes, straight into the stratosphere.  The wind is blowing the ash, containing microscopic shards of glass, into the cruising height of all jetliners -- upto 30,000 feet. The airline schedules all over the world have been disrupted already. What are the likely secondary effects?


The closure of airports for 4 days post 9/11 offers a precedent. It created a downward spiral, catalysed US's entry into two wars in two faraway countries, knocking the economy on steroids that the US was, and still is, into a recession that lasted 2 years, and is arguably still in it.


While there are no more wars likely in a world already tired of wars, there are dangers, real ones, for economies on the brink of bankruptcy. Economies like Greece, Spain, the UK -- they are all very fragile today. The UK is going into an election with uncertainty about political outcomes.


If the airline industry reel for over 2 weeks, we might just see a couple of economies in Europe slipping back into a recession that will probably last quite a bit longer than the ash plume from the volcano.  If that happens, count on Europe as a whole being dragged into a recession, with knock-on effects on the currency rates, that will filter across all stock markets in the world.


I am very worried -- if the perception as above is shared by enough persons operating in capital markets worldwide, rcession and stock market crashes will become a self-fulfilling prophecy. I have covered myself -- yesterday I sold all the shares I held. Will wait for a month for the downward spiral to happen -- if it does not, I will re-enter the markets.
