If you are on the short and you are trying to calculate the exact buy in point--and it is a hundered thousand shares you are buying>>>>>count me out>>cause I don't gamble my money. On sector>>>if you have 1500 or so I'd keep (with an investment perspective) as the U.S. is expecting (from reports Ive read) a second half turnaround in advertising expenditure. In terms of charting>>>you should follow the usual indicators--look for a bottom being established--higher highs and higher lows---look for some stability>>>watch for signs it is beginnig to trend.
