I believe they track identical
That is why I would have thought you to trade TNA with the higher percentage of return.
For me when I am watching a chart/quote and a projected target it is much easier to identify with 44, 45, 46 than 73.50, 74.25, 74.75.
One of these days I might get to the point where I just trade the chart and ignore the pricing but not yet.
Also the lower priced TNA is easier for me to track the number of shares to target a profit, say 400 shares each $1 uptick is $400 rather than 200 shares and a 1.50 uptick is $300.
My mind doesn't like to work math.
Again, I probably should start focusing on the chart/price action rather than looking for targeted 'even' price/profit targets, as the Index support/resistance doesn't always offer up a nice round $ sign on the tracking stocks, but that is how I try to target most of my trades.
And, Yes, why not use the stock with the higher % of return since they track nearly identically?
Have a wonderful weekend
Good Luck to All! :^)
PLAN the TRADE and TRADE the PLAN!
