RE:RE:RE:RE:RE:RE:Tìme to take profits Eeeesh, I can summarize how I do it, but I am no trading Guru so take my comments with a BIG grain of salt...
First off, I consider where we are in the current cycle (in my mind I think we are just at the very tip of the iceberg of this cycle). Based on this view, my Stop Loss would not be very tight (ie. not too close to current price it is trading at). After that, it's pretty simple (I like to keep things simple)...I move the Stop Loss up as the price of the stock goes up (depending where it's currently trading at). In the case of USA, it's trading at $4.77. So, I would wait for it to move up say $0.50 and once it has, I then move my Stop Loss up $0.50.
The biggest trick is figuring out where to put the Stop Loss in the first place. So, I consider all of the following levels; RSI (82.15 "Overbought"), Trading Volume (for level of conviction), 20 day / 50 day / 200 day SMA, Upper/Lower Bollinger Bands, where the 20 day is to the 50 day to the 200 day. And then where the obvious "Support" and "Resistance" levels are on the Chart.
"Conventional Wisdom" says the 200 day is generally the strongest support level. If it goes through that all of the stock's price momentum is essentially gone. Not to mention, as a Stock falls out of "Overbought" it's momentum is quickly evaporating to begin with.
So, having said all of this (and keeping in mind that none of the above is an exact science, nor is it always correct)...
I would put a Stop Loss in at just under $4.00 and another in at just under $3.50. This is for my "Trading portion".
Like you, I trade around a core holding. I have no intention of selling my core at this point in time. My Core Holding has a Stop in just under the current 50 day / 200 day level (and that is where it will stay, for now).
It's a simple strategy, but it has worked well for me over the years.
