A cross of the 50SMA on the weekly time frame has always been a clear signal of the beginning of an uptrend! DO NOT get shaken out by short term volatility. Log scale and the 50sma show a clear up trend, despite what short term price action may signal in the weeks to come. Now is the time to accumulate and buy every dip.
My take on when I believe the next market crash might ACTUALLY happen based on simple trend following indicators on the monthly time frame. I am NOT a bear in this market... not yet at least. But there is nothing wrong with being defensive and on the lookout!
Bottom in OSTK could be in. Showing Positive divergence on RSI, rising volume and Finding support of monthly and Yearly pivots. OSTK is approaching very depressed levels however, so I would place stops below recent lows.
