Trade Strategy and Execution Flashcards
trade motivation
(1) Profit seeking
(2) Risk management and hedging needs
(3) Cash Flow needs
(4) Corporate actions, margin calls, and index reconstitution
2 considerations of Profit seeking trading motivation
(1) Rate of alpha decay (higher rate -> shorter time frame -> trade urgency
(2) Minimize information leakage (alert the market to the security
mispricing through their trading activity)
kind of rate of alpha decay
(1) trade on daily news flow
–> higher alpha decay rate
–> higher trade urgency
(2) trade on long-term fundamentals
–> lower alpha decay rate
–> lower trade urgency
the aim of Risk management and hedging needs
(1) To maintain target risk exposure
(2) Rebalance after change in market conditions (targeted duration)
(3) Remove risk factor from a portfolio (hedge FX exposure)

TWAP
+ Time-weighted average price
+ TWAP ignores volume
+ appropriate for managers who wish to remove the impact of outliers
VWAP
+ Volume-weighted average price
+ average price of all trades, weighted by volume
+ use when they want to participate with volume patterns over a day
+ achieve the objective of using the cash received from sell orders to fund buy orders of the rebalancing
Arrival price
price of the security when the order is sent to the market for execution
Scheduled algorithms
execute trades using rules driven by historical volumes or specified time period
Charateristics:
+ High liquidity
+ Small order
+ low urgency
Include:
+ Percentage of volume algorithms
+ Time slicing algorithms
Liquidity-seeking algorithms
take advantage of favorable liquidity conditions when offered by the market
Charateristics:
+ low liquidity
+ High urgency
+ High size order
+ Infor leakage concern
Eg: wait large order appeared -> enter BUY
Arrival price algorithms
seek to trade close to market prices prevailing at the time the order is entered
Dark strategies/liquidity aggregators
+ execute trades in dark pools,
+ with aggregator algorithms attempting (aggregator algorithms: thuật toán tổng hợp)
+ optimize trading across multiple dark venues.
Smart order routers (SORs)
+ algorithms
+ determine the best destination (either lit or dark) to route an electronic order to lit/dark or both (the market must have both lit & dark)
+ get the best result
dark pool
+ is a privately exchange for trading securities.
+ allow institutional investors to trade without exposure until after the trade has been executed and reported
High-touch approach
+ involve high levels of human involvement
+ required for large trades (known as block trades)
+ Use in less liquid market
+ >< Electronic trading
+ 2 types of high-touch approach (base on who assumes the risk of trading the order):
* principal trades (broker take risks related exercute):
* agency trades (broker only lam trung gian)
direct market access (DMA)
+ allows buy-side portfolio managers/traders to access the order book of the exchange directly through a broker’s technology infrastructure.
+ used more for futures than for options
