The sell-off did pick up quite a bit of momentum once it broke below 80.25 but the psychological level at 80.00 was enough to attract some buyers back into the market. Plenty of month-end turnover going through but buying any big dips in line with the very strong recent uptrend still makes sense to me. The 38.2% retracement of 76.05/81.60 comes in at 79.51.
