People's situations are varied. I had a position in AZS that I was not going to sell to get into LYC in March so there was no point in looking but having held LYC previously, kept it on my watch list. That stock has now been taken over and it delisted today.
I'm entitled to consider what my exposure is and take other positions. I have biotechs, explorers, gold explorers, just bought an early Cu explorer.
It all depends on what stage of the development cycle you want to buy. I like to buy early, then increase my exposure as turning points are reached and the stock matures. Sometimes that really pays off.
There's a lot going on internationally and this is the most complex and potentially volatile time in investing history at least in my lifetime. Some are saying it has resemblances to 1929.
