BullRunner, thankfully I sold some on R-I results as well. Had kept the whole thing from my wife until R-I results and had intentions to sell all remaining shares when sp hit $20. Unfortunately once my wife got involved in watching, she urged me not to sell. Don't blame her since there were some here at the time clamoring that this should be valued at over $100.
But looking back at it, selling at least a portion, as I did on R-I results, helped me diversify my accounts to where now Amarin (although I have kept buying more from time to time) is less than 8% of my taxable portfolio and less than 15% in my IRA. The other stupid thing I did (it turned out to be stupid but thought it was great at the time) was when the sp dropped to 13 (day before DuDisaster decision) and then again when sp dropped to 4 (after DuDisaster) I converted some Amarin shares from my retirement account to a Roth. Needless to say that Roth account is hard to look at.
Glad that I will be dead when my beneficiary sees it!
