Great thread, I'm going to throw in my 2c, its like group therapy????
Oleg must think about it, how could you not, and with the benefit of hindsight it was the wrong decision, but hard to say it was the wrong decision for him at the time, its personal. He saw a bigger pay day than he's ever seen before and youngish guy with a family, sometimes you have to cash it in.
Personally I've sold 3/4s of my holding, in four bites on the way up, Every time I've sold DRO has reached a size where its my largest holding and I ask myself.....
1.would I buy into this stock with this much weight, at this price. definitely not, so holding this much weight is irrational. Cut it back to something more defensible.
2. What would I tell my new to investing mate if he/she said they'd just put 15-20% of his portfolio into DroneShield at these prices?
I also have some history being terrible at selling once a stock like this is on the way down. I've seen 10+ baggers in Pointerra, Appen, Nearmap and Dubber all collapse to a point I've made nowhere near as much money as I should have, and when I look back I can't believe I held so much in some of those businesses at those prices.
For me (still short on housing, grateful i have one, but 4x kids in a 3Br), it's now the sort of money I can't justify holding at risk. By selling DroneShield on the way up, I've probably turned an 11x bagger into a 6x bagger at present, which definitely engenders some reflection. Ultimately I'm ok with it, I know because of this I'll never be roaring kitty, but I'm intent on getting rich slow instead!
