Is the bull run over? I know before a bear market supposedly all the spec shares rise for no good reason which has happened - and the Dow seems to have had its biggest drop ever in one day now two days so far.. that was a huge drop, surely it’s not just a blip on the radar and everything will continue as normal? It’s not exactly just a minor drop.. I feel like things might recover and then drop more or go sideways but I’d have no idea I’ve never traded during a bear market before so I don’t know what to expect? Whats going on with the market
