As the saying goes..."Buy Low and Sell High." We are at all-time highs in the market so basic common sense would tell you to sell. You. of course, want to look at the context of the market but all things being equal it would make basic sense to be on the sell side of the market at this point.
The best way to get in at this point for traders would be to sell calls and/or buy puts. I wouldn't use iron condors at this point because of the potential of the market to go down quickly.
For longer term investors who are in a dollar-cost averaging strategy, I would hold off buying anymore shares until the market dips some more. If you just have to buy and can't stop yourself, only buy small lots but make sure they are dividend paying stocks.
