Market Making
Activity where a firm’s trader stands ready to buy and sell a particular stock on a regular and continuous basis at a publicly quoted price on a listed exchange
High Frequency Trading (HFT)
Type of trading using computer algorithms to rapidly trade securitites
High speeds, high turnover rates, and high order-to-trade ratios
Making profits on very fast trades, with gains even being cents
HFT firms perform “Market Making” activities using a set of high-frequency trading strategies that involve:
placing a limit order to sell (or offer) or a buy limit order (or bid) in order to earn the bid-ask spread
During periods of extreme volatility, firms…
are under no obligation to maintain this activity
Impacts of HFT
Liquidity
Volatility
Price Discovery
Market Confidence
Impact of HFT on Liquidity
Reduction in bid-ask spreads and an increase in trading volume
However, trading volume and narrower bid-ask spreads may not be a reliable indicator of liquidity during times of significant market volatility
Impact of HFT on Volatility
More aggressive HFT strategies may increase stock volatility
HFT Liquidity detection strategies “front run” ahead of large institutional orders amplifies price swings
Front Running is the illegal practice of having knowledge of your client’s orders and executing your own orders first
Front Running
Illegal practice of having knowledge of your client’s orders and executing your own orders first
Impact of HFT on Price Discovery
Although HFT strategies are very rapid to help prices be more efficient to reflect new information in the short term, their effect on long term price discovery is less clear
HFT strategies are agnostic to a company’s fate and intrinstic value
Impact of HFT on Market Confidence
Sophisticated “Algo” strategies and access to Dark Pools used by HFT firms give them an advantage over regular investors
Benefits of HFT
HFT has made markets more liquid and decreased transaction costs
Harmful effects of HFT
Traders who post standing limit orders that cannot reflect changes in value due to news changes fast enough and lose to HFT
Very Harmful effects of HFT
HFT Traders are front run traders who are working large orders, making their trades more expensive. Quote matchers profit from standing limit orders by trading ahead such orders by improving prices slightly
Systematic risks posted by algorithmic trading
Flash crashes
Algos out of control
Market terrorism in the wrong hands
Markets need to be slowed because:
fast HFT will make slower HFT go out of business, which decreases competition, making the few firms in the business increase spreads and thus transaction costs will rise
Dark Pools
Private exchanges not accessible to the public, usually owned by a broker-dealer named as such due to their lack of transparency
Objective of Cycle Analysis
Attempts to find recurring major and minor peaks and troughs in price movement for better trade timing
Cycle
Defined as price movement of a market from a local bottom to a local top and back again
2 arguments against the Cycle Concept
If prices behaved in pure cycles, like radio waves or tuning forks, the numbers would easily fit into mathematical formulas that would give us precise predictions similar to what we know about ocean tides and sunrises
We have been unable to identify causes of specific cycles that many agree do exist in prices
3 qualities of cycle
Amplitude
Period
Phase
Amplitude
Measures the height of a wave from peak to trough, signifying the strength of a cycle
Cycles are measured from ____ to _____ as the tops tend to take more time to develop
Trough to trough
Period
Length of a wave is the time spent between troughs
Phase
Measure of time location of a wave trought, the difference between troughs of different waves
4 principles to cycles
Summation
Harmonicity
Synchronicity
Proportionality
Summation
All price movement is a simple addition of all active cycles. By combining each cycle & projecting forward, future price targets can be forecast.
Harmonicity
There are waves within waves and that they are usually related. Adjacent cycles are often related by small whole numbers, there is a constant ratio applied to cycles
Synchronicity
Refers to the tendency for waves of differing lengths to bottom at the same time
Proportionality
Relationship between the cycle period and amplitude. Longer-term cycles should also have greater amplitude. There should be a proportional relationship between cycles of differing periods.
For example, if a cycle’s period is 40 days, it should have proportional amplitude that is 2x the amplitude that has a 20-day period.
Variation
States that the 4 principles are just strong tendencies and that they are not hard and fast rules
Nominality
States that there tends to be a nominal set of harmonically related cycles that affect all markets
Translation
The reason we study lows in cycle analysis is because longer and shorter cycles tend to synchronize at their lows. Peaks almost never synchronize
Peaks should occur at the halfway of the cycle
Their location away frmo the center point is translation
Kondratieff Waves
Economic phenomena that are not necessarily obseravable in commodity and stock prices.
Winter: a period of concern, fear, panic, depression
Spring: a period of fear of depression, fragile confidence
Summer: a period of growing confidence
Autumn: a period of increasing confidence, that turns into extreme confidence and euphoria
4 year/Presidential/Kitchin Cycle
The US suffers a recession every 4 years
Most widely and easily recognized stock cycle
Weak during post-election & mid-year (years 1 & 2)
Strong during mid-year 3 and pre election
Seasonal Patterns
Sell in May and Go away
August and September being bad bonds for the stock market
October, November and January being the best months
January Barometer
Old stock market adage that states “as the S&P goes in January, so goes the year”, implying that January will foreshadow a year of positive equity returns
January Effect
Theory that states that small cap equities tend to outperform the broader market in the first few days of the new trading year, due to investors buying back stocks that were sold for tax loss reasons at the end of the previous fiscal year
No longer works well in recent years as arbitrageurs have solved this
Inversion
When a peak occurs where a cycle low is expected
