Sheff - waiting for the bios or any sector to flush out and retrace/correct is painful for sure, but as most of us can attest it always happens to all sectors, its a death and taxes type thing- and it's never a question of: "if", but rather "when" it will occur.
The 10-20% haircut you mention is happening for sure on many stocks and in process on others; question is imho when do side liners become buyers and trying to get that when it starts vs when it has gone on for 10% in the reverse. lol
The greenies and <1% losers are imo are the most interesting, but finding them is tough right now.
Some measuring device is good, but which to choose: 52 week low or some small % over it? Very low debt, lots of COH, some very near by event 2-3 weeks hence etc., etc. Can't use PEGs or PEs on many of the under $10 stocks. Can't use strong dividends since hardly any offer that.
Perhaps those with topline growth Q over Q and declining loses. Not sure, it always seems like a dilemma each time I encounter like situations, for me anyway.
