Keep your long positions in stocks during the start of next week.
Major markets are at multi year highs. The sentiment is not euphoric at all. Scepticism prevails from underinvested traders who cannot justify the move of the last 3 months and missed the move.
Stock indices like the S&P and the DAX are very likely to test their own historical highs before any serious correction takes place.
If you are not in the market already, avoid short positions. Short positions are bad bets in this environment. You cannot pick the end of this move.
