Don't think that you'll see much bullish activity in the market until at least Q3 of next year, to be honest.
We're still unsure of whether or not we've hit bottom at the moment with sentiment in the market extremely negative still. As I've expected, the previous rally that some people took as the signal to a new bull market was in fact, a bull trap, with a sizable correction which happened yesterday.
Based off the most recent bear market of 2014, we've still got some time to go before markets will fully recover. I do think that right now is a great buying opportunity because of the cheap prices, but don't expect prices to be rising any time soon. In these circumstances, holding is always a better policy than panic dumping.
