I use a 1% (.5 under .5 over) envelope and don't mess with it too much. I adjust my fair value calc for each individual stock's beta.
Today was filled on axp, bac, and sbc, all short. Lost 6 cents on axp, it kept going up. Lost 15 cents on bac, was a little slow to get out, it kept going up. lost 3 cents on sbc- it rallied a bit after I got out, but collapsed after taking out yesterday's hi by 5 cents.
In the overall scheme, not bad, since I have been profitable for 7 consecutive days before today.
I had order in for kss, but cancelled it when it did not open after more than 5 minutes. It would have been filled short. Might of gotten stopped out, or could have held through initial bounce and made money- hard to tell without actually being in the position.
Unfortunate that I ended up overweighted short financials. Other stocks on my watchlist, but that I do not currently trade, were great performers today. I may add a name or two to my order list as I'm getting pretty comfortable with the technique.
Interesting today that although the s&p was down, not much filled on the long side.
I'd like to know what everyone's thoughts on risk management are. I'm thinking I'm willing to give up 1% or so in a worst case scenario, although in practice my losses have been much smaller.
Don occasionally gives examples of waiting signifigantly larger moves against his position (ie: aol, txn). Any thoughts?
