Lecture 8: Technical Analysis - Moving averages Flashcards
A ?? is the average price of a security over a set amount of time.
A moving average is the average price of a security over a set amount of time.
? Moving Averages (SMA):
- the most common method used to calculate the moving average of prices.
- It simply takes the ? of all of the past ? prices over the time period and divides the result by the number of prices used in the calculation.
Simple Moving Averages (SMA):
- the most common method used to calculate the moving average of prices.
- It simply takes the sum of all of the past closing prices over the time period and divides the result by the number of prices used in the calculation.
The shorter the period used to calculate SMA, the ? variation and the ? it fits with the actual price movement.
The shorter the period used to calculate SMA, the greater variation and the better it fits with the actual price movement.
If actual price data cuts and moves below SMA, it’s a signal to ?.
If actual price cuts from below and move up SMA, it’s a signal to ?.
However, because price has already fallen/risen, this is a ‘?’ signal.
If actual price data cuts and moves below MA, it’s a signal to sell.
If actual price cuts from below and move up MA, it’s a signal to buy.
However, because price has already fallen/risen, this is a ‘lagged’ signal.
The longer the period used to calculate SMA, the ? the lag between actual and SMA.
The longer the period used to calculate MA, the bigger the lag between actual and MA.
‘Crossover’:
If the short-run MA cuts the long-run MA from below => ? signal.
If the short-run MA cuts the long-run MA from above => ? signal.
‘Crossover’:
If the short-run MA cuts the long-run MA from below => buying signal.
If the short-run MA cuts the long-run MA from above => selling signal.
’?’: when short-run MA cuts long-run MA and quickly reverse after a short period of time
=> if we follow the buy/sell signal of whipsaw, => ?transaction costs.
‘Whipsaw’: when short-run MA cuts long-run MA and quickly reverse after a short period of time
=> if we follow the buy/sell signal of whipsaw, => high transaction costs.
Empirical evidence suggests that Technical analysis is usually used in the ?-run to generate buy/sell signal.
Empirical evidence suggests that Technical analysis is usually used in the short-run to generate buy/sell signal.
