I agree with you both...
I don't think its a bad idea to hold some ABL but you need to adjust your portfolio for risk and this company's outlook at the moment is uncertain.
You can't compare it to a Goldman Sachs which was far more solid at the time of Buffet's investment.
So yes, one could take a punt and it might come off spectacularly but you would be mad having 17% of your money in one company with this much uncertainty.
My advice would be to reduce your holding to max 5% and put the proceeds somewhere else.
Im sorry, I can't rationalize holding ABL over CML, ELI, SAB, PNC and BAT to name a few. Bad results and no indication of the results getting any better next time, I hardly think the odds are in his favour. If you honestly think holding ABL is a better option than swopping out for CML long term then I'm very confused. Being able to say that you made a mistake is an important part of investing, to hold ABL for a couple more years to hopefully get back what you lost is not worth it. Anyone else think that holding ABL is not a good idea??
Do not try and bend the market. That's impossible. Instead... only try to realize the truth. Then you'll see, that it is not the market that bends, it is only yourself.
