SPY is definitely in an uptrend. It will continue moving higher to 290 once it's breaks out of 280.
A lot of traders think 280 is where the market will correct and head lower, so they are taking short positions. Markets are never that obvious and will do the opposite of what everyone is thinking.
The current on-going trade war has pushed the Chinese market down. The GXC (China ETF), is still in a down-trend and may find support at 82. If it can hold 82, then it's a good long term buy at this level.
Still bullish on Apple. It's stretched away from the 50-day moving average. Most likely head lower in the short-term to 210, before heading back up.
Manage your risk: Use a stop limit or a protective put.
