Pre Earning Games

The name "Pre" mean to play before the earning announce... most of the time share price drop after earning announce eventhough profit reported, the market is uncertain, so mostly people are playing pre-earning games, some sold 1 day before , some take money off the table before the announcement and put tight stop. Good example is MU ( micron ) shown below, pretty volatile and a bearish engulfing candle wipe out previous few days profit, rest nicely at 20 days moving average, need to monitor will it get technical rebound on Monday. Nice retracement we have here
