Depends on when you bought SIAF.
For the past 3 years (at least) I only invest in special cases.
I bought SIAF because of the stock dividend. It is quite exceptional for a company not to deliver when they clearly should have. And, they didn't pay the cash dividends either. That is bad luck.
As for HERB, I think they have a plan. But it hasn't materialized for some reason. Could be many reasons, usually legal hurdles. Just ask Solomon. Obviously, the pps just keeps dropping in the absence of news. But I don't consider that a bad investment either.
Do I need to go back further? These two have crushed me.
