Too many alternatives......My initial purchases of GUD were in June of 2015 and I added to my position last year.
I'm a pretty patient guy, however with the recent declines in the market I see better opportunities and so I sold all my shares recently. FYI, my real annualized return on GUD has been 2.3% - disspointing is an understatement.
I do not sit on high levels of cash in my own accounts so why should I stay invested in a company that does?
IMO, they have just been way too slow at deploying the cash. I won't won't speculate on why as others on this board have already.
Best of luck to all.
