Basis matters in both an IRA and taxable account, particularly in a subsequent buyout or LTCG sale. I sold those AMRN shares in chunks; the first chunk of 2700 sold at $0.63. That first chunk of 2700 shares had original bases ranging from $18 to $21 per share. The remaining chunks of 2070 and 15,990 shares were sold at $0.64/share; those chunks each had varying bases, all greater than $3/share. I now have ~ $1610 cash in the IRA; I started with a little over $2 cash.
Some years ago I had accumulated 1,000,000 shares of OCAT. Management proposed a reverse split of 1 share for every 100 shares; shareholders approved. Astellas bought my 10k shares at a substantial $$$ LTCG. OCAT’s CSO had invented, and patented, a way of making/growing a variety of human cells and human organs.
