Quote from canslim: Is it correct to conclude that technical analysis of individual securities is a completely different science than for ETFs?
The simple answer is "no". Data is data and the maths you apply to it don't notice if it is an ETF or an individual stock. But, like any analysis, there are some conclusions, as you note in your next comment, that don't necessarily follow.
For example, if an ETF is going sideways, it could mean that half of the holdings are skyrocketing and half are tanking, thus creating a sideways average.
This would have nothing in common with theanalytical conclusions one might draw from an individual stock moving sideways. I haven't seen a distinction between technical analysis of individuals vs ETFs but it seems very unlikely that they would behave graphically the same way for the same reasons beyond overall market trends.
You've answered your own question. That the underlying stocks don't necessary track the ETF is the most important thing to remember if you trade stocks based on indices or ETFs. People get people into trouble when they conclude that "the market" (or in this case, an ETF) is strong, so I'll buy a particular individual stock in anticipation that it will rise with the tide. The TA you did on the ETF applies only to that ETF, not the underlying issues.
Being that your handle is CANSLIM, you understand relative strength. Study the RS of a stock relative to the ETF and trade the issues that are most correlated but that show a desireable beta. But even then, if you are using TA, you'd want to then apply your tech criteria to that individual stock.
Anyone know of a resource that expands on this idea?
Stockcharts.com has a few resources to evaluate groups of stocks. For instance, here is a <a href="http://stockcharts.com/charts/candleglance.php?AA,AIG,AXP,BA,CAT,C,KO,DIS,DD,XOM,GE,GM,HPQ,HD,HON,IBM,INTC,JNJ,MCD,MRK,MSFT,MMM,PFE,JPM,MO,PG,T,UTX,VZ,WMT" target="_blank">Dow "candleglance" group</a> of the 30 stocks in the INDU. Even as the INDU made new all time highs, the individual issues were all over the place. You can also make "market carpets" with stocks you select.
best, amg
