Trading and Performance Evaluation Flashcards
Motivations/Rationals
- Profit Seeking
- Risk Management Hedging Needs
- Cash Flows Needs
- Corporate Actions, Margin Calls, and Index Reconstitutions
Profit Seeking
- Active portfolio managers are trying to outperform a benchmark by generating Alpha.
- Done by trading securities that they believe are under/over-priced
- Management needs to act on their insights before the rest of the market does
- Key part is Alpha decay
Alpha Decay
- Deterioration of Alpha once an investment decision has been made.
- Management trades on the flow of daily news, and has a high urgency of trading
Dark Pools
- Trading systems with low pre-trade transparency; trades cannot be seen until the trading occurs (post trade)
- Disadvantages: Traders cannot see orders on the other side they don’t have any of the pre-traded likelihood that a trade will be executed
Lit Venue
High pre-trade transparency, you can see both sides of a trade when an order is entered “stock exchange”
Cash Flows Needs
- Trades are primary caused by subscriptions in the fund or redemptions out of the fund
- If a fund has a lot of illiquid holdings it will be difficult to invest new client funds in a short-term period
Cash Drag
- Cash doesn’t earn a return which will reduce a portfolios return
- To avoid cash drag a portfolio can use a cash equitization strategy (ETFs or derivatives)
Index Reconstitution
Overtime a index adds and remove securities
Factors that Dictated the Appropriate Trading Strategy
- Order Characteristics
- Security Characteristics
- Market Conditions
- Individual Risk Aversion
Order Characteristics
- Side of the Trade: The direction of the order (buy, sell, short sell)
- Absolute Size: The number of the securities being trade
- Relative Size: Orders that make up a higher percentage of the ADV will have a significant impact
Market Impact
- Impact on the price of the shares by a large order “buying liquidity”
- Market Impact costs and timing cost are inverse in nature
- Upward pressure: act of buying a lot
- Downward pressure: act of selling a lot
- Large block order: Tries to trade overtime with less urgency to reduce the impact.
Security Characteristics
- Security Type: Different types, trade in different markets, and have different costs
- Short-Term Alpha:
- Price Volatility: If prices are fluctuating widely implies high execution risk.
- Security Liquidity: More liquidity the narrower the bid-ask spread.
Short-term Alpha
A high urgency trade due to capturing mispricing there will be a high rate of alpha decay for an active management
Impact and Execution Risk
These are Inverse if one goes up, the other goes down
* Market Impact costs: Trading to quickly information leakage
* Execution Risk: Trading too slowly; adverse price movement
Implicit Costs
Hidden, largest part to a trade’s costs
* Market (Price) Impact Cost: (Cost of buying liquidity) Actual execution price less the price when the order is presented to the broker (M - B)
* Opportunity Cost: (Cost of the investment idea) The difference in price when the order was cancelled and when the order was placed “missed trade”
* Execution Risks: (Timing, Delay, or Slippage Cost) The price when the broker presents the order to the market less the price when the original order was presented to the trader (B- T)
* Bid-Ask Spread
Explicated Costs
The tangible visible cost you can see:
* Commissions,
* Fees
* Stamp duties
* Taxes
Reference Price
Are a key impact for the actual costs of trading for post trade evaluation
* Pre-Trade
* Intra-Trade
* Post-Trade
* Price-Target
Pre-Trade Benchmarks
Know before the start of the trading there are 4-types
* Decisions “Benchmark” Price
* Previous Close: Closing price on the previous day
* Open Price: Opening price of the day
* Arrival Price
Decisions “Benchmark” Price
“Original/Initial” The original price when the investment was order initiation “conceive”.
A lot of orders are initiated when the market is closed to the previous day’s closing price is used.
Arrival Price
“Revised Benchmark Price”
* Market price when it was sent to the market for execution if the order was fulfilled
* If an order wasn’t fulfilled at a limit order price, then the limit price needs to change or the price of close of previous day.
Intraday Benchmarks
Based during the trading period
Normally used by the portfolio manager who trades passively over a day the ones included are:
* VWAP
* TWAP
Post-Trade Benchmarks
Determine after trading has been completed (most common is the closing price)
Disadvantages: The closing price is not known until after the trade has been completed; cannot access performance during the trading horizon
Price Target Benchmark
- High urgency for with high alpha decay
- For profit seeking portfolio managers trying to earn a short-term alphas
- Is quick strategy that would purchase a security below a predetermined price
High-Touch Approach
High level of human interaction, for large block trades, and/or less liquid markets
1. Principal Trade: Agency
2. Agency Trade: Broker
