core position just means I will hold onto it

not trading it. Since I could not predict up and down of market, but I know some stocks are very undervalued, so I would buy those undervalued stocks and wait patiently for it to go up, like abk, the lowest lot I bought is 1.24, one time it is up almost 10 times for me, now it is back to 3 times. I never touched my core position, but I buy and sell other position because of big volatility.

So basically, I divide my position into two parts: core position and trading position.
