"Because then you have 2 happy clients, not one"

I don't know how happy I would be with a broker that got me out of a stock that doubled or trippled after I sold it. Some may never look back after they sell a stock. My experience is that every one looks in the rear view mirror of life. I have an older (90) friend who owned 100 shares of Bershire Hathaway way back when (1960's). His broker got him to sell for a nice profit shortly after he bought it. My friend never stops talking about it. A better broker would IMO get both clients into a stock that was going to go up. Tell the first to buy more and get the second one in at a low price. Some brokers would get all their clients in on such a great stock. With profits from so many clients the broker and clients would have more money to work. I'm holding. I don't want to be telling "only if" stories when I'm 90 !!
