@KYHBKO:my investing muse - 3 days rule for "buy the dip"in the market, there is a "3 days rule" that advises the following:If a stock suffered a big drop in a single day (high single digit or more in percentage %), it is usually advised to consider buying after 3 days. I have recently recommended a BAD (buy AFTER dip) trading strategy over buy the dip (BTD). this may help us to avoid catching a falling knife instead.with $Facebook(FB)$dropping 22% post trading hours, the impact has spreaded to other social media businesses like $Twitter(TWTR)$, $Pinterest, Inc.(PINS)$& $Snap Inc(SNAP)$which
